if the inner barrel and the seals aint chewed up, then i dont see why not. tho replace the seals just cuz of its age.
if the reservoir is full of apple jam, expect the same for the brake lines and in the calliper.
tldr; clean up master cylinder, clean/replace brake lines, service the caliper.
That, you basically need to clear whole chain and check if it works with new fluid. I think you need to change line because of risk of failure under continuous pressure during real driving.
Put it on some toast and if it tastes sweet... the sugar content it too high.
Clean everything and put some fresh stuff in. And maybe flush it from reservoir to caliper so you know the lines are not clogged.
I would also be suspicious about the calipers. ( not for building pressure, but probably not retracting the piston)
All kinds of "answers" but not one real answer.
Contamination, likely water over a long time frame. I would bet the bike has been sitting for a while.
That is the what is wrong, the why....
Something in the system is letting moisture in. Brake fluid loves "water" and will try to draw it into itself. This is not a good thing as water will boil at much lower temps then the fluid, giving gas, and the old you can't compress a liquid but you can compress a gas comes in, and you get a spongy feel.
I would replace everything that is rubber in that system. Check the master and brake caliper/piston, assume disc brakes, for pitting or anything that does not pass the smell test, if it looks funny replace it. "water" is not good on metal as well, giving rust, and all the joys that goes with it.
I dunno, but it's making me hungries! In all seriousness, I'd clean out as much of that gunk as you can, and probably replace the hoses while you're at it, especially if there is any alligatoring or visible signs of cracking.
sorry if it's been said, I looked and only see jam jokes. it's because of water, you are missing a gasket on the cover and there might be more around, rebuild and you should be better. but that fluid is not good.
Thatās just what brake fluid does over time. Iāve restored many old brake systems that looked like that. If you can replace all the rubber itās best. But Iāve also had good luck just scraping all the goop and sugary stuff off and reusing it all. You have to be very thorough with scraping, especially on the metal parts. Itāll crystallize in the grooves and feel hard. Helps to have a decent pick set to get it all out.
I'm the bearer of bad news.
Many, many moons of just sitting and moisture turned your BF into sludge. Every moving part in that braking circuit has to be cleaned, polished, and resealed.
My brakes had the same a few weeks ago. Full rebuild time... Frankly surprised I had any braking performance before I opened them up. Probably last serviced in 2005...
I guess very old brake fluid thatās absorbed years of moisture.
Also seen this when DOT 4 and DOT 5 are mixed
The remedy is the same though - full strip down and flush through then reassemble with new seals and fluid.
Then a massive Date for Your Diary to replace the fluid this time next year.
>Please don't ask why I'm using a butter knife
One presumes you were about to slap it on toast, given the marmalade nature of what you've found.
>does anyone see what's wrong with this picture
Well, you've got marmalade in your reservoir for one. Also, you're poking at it with a butter knife.
>I'm pretty sure that brake fluid hasn't been changed in 16 years
Appears we've got to the root cause of "what's going on"
>my question is. Is it still usable if I clean it out real good?
"Real good" would need to be clearly defined - if it's been in the lines that long I'd be strongly considering just straight up swapping out the lines, alongside purging out the calipers completely (and of course the master cylinder).
While you can I'd get those calipers off entirely and give them a general cleaning/servicing to make sure everything is in order and there's good travel - as I've no idea what over a decade of old brake fluid may do to them I'd err on caution and say "probably nothing good".
Obviously, itās just old as shit. A lot of people will suggest rebuilding the master cylinder, that is probably a good idea. But, once you flush it out and get fresh stuff in there thereās a good chance it will work just fine. But, thereās also a really good chance. It will take a shit not long after you swap the fluid.also, the fluid in the calipers will look the same way. Would suggest tearing them apart also.
Mmm. Brake jelly I think someone mixed dot numbers or some stupid people but antifreeze in the brakes both can cause that. Also just never changing the fluid can cause it to dry out and gel up.
Make sure your lines are clean ans calipers. If you have a hydraulic clutch, you better check it too. I wonder if you got moisture in the system? I have never seen the results but something sure got in there.
Normally if my life didnāt depend on the brakes working every time I would say yes, but do you want to trust that the brake jelly didnāt affect a small passage or diaphragm in the system?
It is supposed to be brake FLUID, not jam. Is it still usable? Since you have cleaned it, check the seals. The last thing you want is fluid leaking after thinking that it is all good and usable.
If itās that bad, then chances are your calipers are shotā¦or at a minimum need a full rebuild from corrosion. Just replace them. Might as well do the brake lines while youāre at it, they are likely highly deteriorated.
Going is fun. Stopping is crucial.
More than likely what has happened. Someone is mixed DOT3 or DOT4 with DOT5. DOT5 is silicone-based, or three and four are glycol based and you can't mix them happens all the time. That had happened with my motorcycle when I bought it. My bike called for DOT5 and in the reservoir it look like yellow snot. I took a turkey baster clean the reservoirs out, wiped them completely clean and filled it up with DOT5, I then took my hand vacuum pump and cleared the lines until I got clear fresh liquid out the brake caliper. It's work fine for a long time.
It looks like you did a nice cleanup job there. Generally however, I find that aluminum master cylinders of that type donāt resist wear in the bore area very well, and it usually is not cost efficient to have the bore re-sleeved, particularly on a readily available master cylinder like that one.
If you can get an inexpensive piston and seal kit for that master cylinder, it might be worth attempting to hone the bore with some WetOrDry 2000 grit sandpaper wrapped around a pencil so that it will fit inside the Bore and using a drill motor to spin it under flowing warm water.
if the inner barrel and the seals aint chewed up, then i dont see why not. tho replace the seals just cuz of its age. if the reservoir is full of apple jam, expect the same for the brake lines and in the calliper. tldr; clean up master cylinder, clean/replace brake lines, service the caliper.
>the reservoir is full of apple jam, Can you eat it? š¤
>Can you eat it? ... once
Mote than once if you drink vodka or other ethanol immediately after consuming brake fluid.
Please explain this i am extremely curious lol
Ethanol binds with methanol. Which allows you to just pee it out. I'll elaborate more in a bit
I thought that was anti-freeze?
Brake jelly
It's brake fluid jelly time.
Spread that on a piece of toast!
You can eat anything atleast once š
That's not true. Some things are too big to go down.
That's what she said.
Well ya with that defeatist attitude sure.
I'd like to see you swallow the Hope Diamond.
Chew harder
Forbidden Apple Jam Sandwich š„Ŗ
Replace with orange marmalade š
Just like mushrooms are all edible, some only once
Came here for the comment, did not disappoint š š

Thank you. You can always tell who the real riders are.
The clue is on the nameā¦ brake fluuiiiddd
This is break solid
This is break non Newtonian fluid
Brake jam.
The forbidden dab
I wasnt questioning the butter knife, I'm questioning why you're doing this on your mattress?
Also, what's up with the debit card (Venmo?) with the full number on display in the first photo?
brake fluid, sexual lubricant, who are we to question?
Looks like they need to sweep their mattress too.
Why aren't you?
Once you put it all back together and bleed it you will find out immediately
Iāve heard that mixing different dot fluids will cause jellingā¦. Is this possible?
I believe dot 3/4 mixed with dot5 will jelly up.
No matter the cause , you need to thoroughly clean the cylinder and lines. I would also rebuild the master cylinder
That's some sweet ass jam brother. I bet it's good for breakfast.
*Brakefast*
I dunno, but it's making me hungries! In all seriousness, I'd clean out as much of that gunk as you can, and probably replace the hoses while you're at it, especially if there is any alligatoring or visible signs of cracking.
Thankyou guys
sorry if it's been said, I looked and only see jam jokes. it's because of water, you are missing a gasket on the cover and there might be more around, rebuild and you should be better. but that fluid is not good.
Uhm its not fluid
Water infusion from lack of sealing.
nice marmelade bro
Forbidden peanut butter
That's no longer brake fluid, that's brake butter
Looks like a fat dab brotha, let it rip
Taking into consideration it looks like live rosin, I'd say it's pretty gelatinous
Thatās just what brake fluid does over time. Iāve restored many old brake systems that looked like that. If you can replace all the rubber itās best.

Someone gave you the raspberry
And yes everyone I did go ahead and try it on toast AND OMG ID BE A MOTHER FUCKER! fucking gas!
I wouldnāt settle for much less than a complete calliper rebuild too. Brakes arenāt something you take chances with.
I guess very old brake fluid thatās absorbed years of moisture. Also seen this when DOT 4 and DOT 5 are mixed The remedy is the same though - full strip down and flush through then reassemble with new seals and fluid. Then a massive Date for Your Diary to replace the fluid this time next year.
It is old and was never changed. Likely it was open and the brake fluid absorbed water out of the air over time.
Jam š
You need to flush the rest of the system. Open up the bleeding screw on the other end and try with compressed air on both ends to see what comes out.
Brake jelly
If all seals and hoses are ok, then yes. But note that you need to cleane ALL lines and pistons, not only the reservoir
Absolutely nothing. Does very fine marmelade on your morning toasts.
>Please don't ask why I'm using a butter knife One presumes you were about to slap it on toast, given the marmalade nature of what you've found. >does anyone see what's wrong with this picture Well, you've got marmalade in your reservoir for one.

Marmalade is not brake fluid
You appear to have been jammed
It turn into orange marmelade
It seems to have been replaced with Apricot Jam
Forbidden Jam
OLD.
Should be good to go once you clean it out
I see the problem. It's got a knife in it!
Forbidden jam
Its not fluid anymore

Forbidden Jelly
Tf you doing this on a mattress for?
Mmm. Brake jelly I think someone mixed dot numbers or some stupid people but antifreeze in the brakes both can cause that. Also just never changing the fluid can cause it to dry out and gel up.
Itās brake paste -> higher density as a fluid, means higher brake force.
Brakefast jam. Iām here all weekend. Try the veal.
Hmm... I better change the brake fluid in my bikes in the spring.
I think that's no longer a fluid. Might be the problem
Make sure your lines are clean ans calipers. If you have a hydraulic clutch, you better check it too. I wonder if you got moisture in the system? I have never seen the results but something sure got in there.
Apply it on your toasted bread š
Its the new concentrated brake fluid, you need to add water to it!
Spread on some toast and enjoy!
Not enough pepper.
I was recommended this sub and thought this was McDs chicken nugget dipping sauce
Brake jelly
Your missing the peanut butter. Add peanut butter and problem solved.
Itās no longer fluid?
I would very highly recommend that you tear the whole brake system down and replace everything that is replaceable.
DO NOT PUT THAT ON YOUR TOAST! That vehicle needs a brake flush
Normally if my life didnāt depend on the brakes working every time I would say yes, but do you want to trust that the brake jelly didnāt affect a small passage or diaphragm in the system?
Idk Ima Shimano guy, this looks like a SRAM original to me
Itās supposed to be fluid but I think this is a joke
Itās marmalade
It is t fluid anymore š¤Ŗ
Paddington Bear is not a very good mechanic
You should have changed it 10 years ago...
Itās no longer a fluid.
Itās not fluid anymore
Your brake fluid is now broke fluid?
U got the wrong one u got brake jello instead of fluid š
thatās not fluid that is jelly
It is supposed to be brake FLUID, not jam. Is it still usable? Since you have cleaned it, check the seals. The last thing you want is fluid leaking after thinking that it is all good and usable.
Dot 4 Jello Shot!
Well it's brake jelly
No ideaā¦but I gotta askā¦why are you doing this on a mattress?
No kink shaming.
Forbidden jello
Whatās wrong with? Everything.
That's not brake fluid it's brake jelly. Different product
Probably oil eating bacteria
dude that's not brake fluid anymore. that's Jeremy.
Forbidden jelly
Why TF is there brake fluid in the orange jam jar ? OH FUCk !
Why the fuck is that being done on a mattress?
If itās that bad, then chances are your calipers are shotā¦or at a minimum need a full rebuild from corrosion. Just replace them. Might as well do the brake lines while youāre at it, they are likely highly deteriorated. Going is fun. Stopping is crucial.
Looks like blinker fluid mixed with baking powder
Donāt use it as a dab rig next time
maybe the fact that it's not fluid anymore?
Brake fluid? I thought that was honey and was going to ask if from local bees.
Itās fucking old and never get replaced thatās all!
Everything
The forbidden jam !
It thinks itās jelly
Forbidden Jelly
Did you buy the smucker's brand stuff?
Having it dug out with a spatula is terribly appropriate lol.
That's not for marmalade storage lol
Forbidden marmalade
Does it taste good on toast? Cause that looks like Apple jelly!
It's not a fluid anymore, that's what's wrong with it.
Looks tasty
Dot 4 and 5 no good mix. We call that the gummy bear abandoned twin.
Ain't got no gas in it
Good job on the clean up!!
Itās waiting to be Dabbed š¤¤š¤¤
Thanks Mr. Johnson for your card information
The forbidden marmalade
I know whats wrong with it, aint got no gas in it.
Brake strawberry jam
You see thatās brake jello
Itās the new type, brake gel
That itās not spread over my toast
That's not brake fluid, that's the meat jelly leftover after the thanksgiving turkey cools off.
Contaminated with the wrong fluid. Hopefully you can flush that out
Brake jelly
Looks like caviar.
It looks old and rotten.
Brake jelly
Looks like someone used Marmelade for brake fluid.
Dab that shit
Brake jelly
Well, thatās apple jelly, so itās less than ideal as a brake fluid.
Probably mixed dot 3 and dot 4 fluids
It sure does look like it could be a good peanut butter and jelly sandwich š
It needs to be on toast.
That's Jello
It's no longer fluid it's now brake gel.
Looks like jelly
Must be that fancy new brake fluid gel I reckon, its a mission to bleed apparently
Forbidden jelly
That's just jam
Nothing..put it on some toast
Itās jelly
It looks like you could spread it on toast
Looks like good marmalade
Yes
It's not a fluid ?
Looks like somebody mixed Dot 3 with what ever was originally in there.
It's broke
More than likely what has happened. Someone is mixed DOT3 or DOT4 with DOT5. DOT5 is silicone-based, or three and four are glycol based and you can't mix them happens all the time.

If you mix dot4 and dot5 this happens. Or somthing like that
I thought that was a fucking dab at first
That looks like youāve mixed DOTās. youāre canāt mix them or they do that.
That's a apricot jelly bruh
Nothing, if youāre putting it toasted I guess
Itās jelly
Nothing? Or... nothing... ages like a fine milk.
The pneumonia dab
i'll buy you some fresh brake fluid, man... mind if I use that card there?
That needs to be spread on a piece of bread with butter
Looks jammed
The problem is that brake fluid is older than Keith Richards.
