Brake Fluid Always Low....... - BMW Forum

kyle_baker · 07-12-2005, 10:02 AM

I have noticed that my brake fluid is constantly needing to be filled back up. Anyone know if the brake fluid could be burning up or where it might be leaking? Where i park there are not ANY oil stains on the concrete. What should I do, other than refill it?

anyone know if low brake fluid can cause clutch problems like no pressure on the clutch pedal until about 2 inches off the floor? I'm hoping my clutch problem is related to the low brake fluid becuase my dad said something about that and when i filled up my brake fluid just about 20 min ago my clutch pedal started feeling like it was coming back, like pressure higher off the floor, still hasn't completely come back but i'm leaving my car running to see if it will work itself out. any suggestions?

Yes! The clutch uses fluid from the brake reservoir. Check you clutch system for leaks too.

that exact same thing happened to me.. i kept filling the brake fluid and every two days it would need more... finally i was able to figure out it the slave cylinder that needed to be replaced.

and yes, it is related to clutch since they use the same reservoir... my clutch did not engage at all... it is pretty easy to change the cyclinder and cheap too.. don't go to the stealership....

good luck!!!

well my clutch seems fine now, it still kind of falls about an inch or two before it has any resistance, still not 100% back. What else can i do? I am going to do a conversion on my 325 to an m3 clutch, but i'd like to wearout my old clutch before i tear open the transmission and mess with the clutch. Were are good spots to look for a leak? just mention a few and i'll see what i can find. thanx for the help guys, i couldn't figure out what was wrong with my clutch. I even had to take out my clutch stop and cut it down once about .5 inches and all for nothing because about 30 min later the clutch was at the floor, lol.

You have a brake fluid leak in either the braking circuit or the clutch circuit. If you can't find the leak yourself and correct it, you need to take the car to a mechanic ASAP. At any moment you could have no brake fuild and no brakes. This isn't something you can wait around to fix.

yeah, i figured out that much, i just wanted to know where to start looking for the leak at.
