Hi. Problem with clutch pedal

[RomeoMPower]

Hi, I am new to this site. I own a 1988 BMW E30 325is. I just noticed a couple days ago that when I push my clutch pedal, it just sticks to the floor with not returning back up. There is also an "airy" sound when I press the brakes, but the brakes still work. So I checked the brake fluid reservoir, and the fluid is at minimum. I just want to confirm this if I need to bleed my brakes or refill the brake fluid. So the clutch fluid is tied to the brake fluid reservoir? Or is it something else that needs to be replaced.

You have a leak in your clutch master/slave cylinder

Do you know about how much it would cost to fix this leak? I don't know much about cars, but I have the service manual though if I can do it myself.

yeah that o u should try to bleed the system first

Don't let the res. Run dry! Trust me, I learned the hard way. and yes the clutch, and brake res. is the same thing. Go buy new brake bleeder valves! They're like 4-5 bux a pair, and will probably be a pain to get out if it hasn't been done in a while. I had to use a small butane torch, and vice grips to get them to turn on my 85 eta.

and it depends where the leak is. Seeing as how your still at the minimum in the res. something is probably just a little loose. If you had a leak in the line itself you wouldn't have anything in there. I would just snug down the brake lines coming off the master cyl. you'll see it under the resivoir, and one coming from the res. itself. While your taking the wheels off to bleed the system take a look around where all the connections are and see if you can find any brake fluid. there's a single line that runs along the driver side and up ontop of the differential, then splits to the rear wheels. the two front head off the master cylinder. If it's still squishy after you check everything chances are somebody let the res. run dry, and you'll need to bench bleed the master cyl.

Just got my car back today from the mechanic. They said it was the slave cylinder that was replaced. It must have been a leak. But i'm happy to drive it again!
