clutch pedal on floor

[Todd Frye]

The Silver Bullet, with 213K on the speedo, just had clutch failure. No warning signs or noises...just pedal completely to the floor. Leaking fluid pools under the car when the brake pedal is pumped (to check for fluid level in reservoir). I haven't crawled under the car yet, but if this has happened to you, I'd like to hear what it took for the fix (parts wise) so when I do get horizontal, I'll likely have the right part on hand. Thanks for your help. Todd Frye 1988, E-28.

Check your clutch slave cylinder located on the trans bellhousing driver's side. That's what mine was, same problem as you have. Of course the brake fluid resevoir must be full, you may just have air in the slave. Clutch and brakes run of the same resevoir.

if you have never changed any parts of the clutch system, I would suggest that you get the slave, the hose in between them, the master cylinder and take a very good look at your pedal bracket since they tend to crack and destroy the master cylinder (same symptoms though, pedal on the floor). There is also a small plastic connector that goes on the master cylinder that most of the times break when you remove it, its cheap ($1) so get it too. The pedal bracket was like $40, the master like $55, the plastic connector $1, sorry but the other parts were replaced by the previous owner less than a year before I bought my car!
Good Luck!

bad and when they leak it messes up the floor mat. BTDT.

my '87 535 did the same thing, on hot days after being parked for about 10 minutes or so. The pedal would stick to the floor, I'd reach down, pull it up, shift to the next gear and it would stick again. After driving a short distance it would work normally. I changed the clutch slave cyl. (the one from BAVAUTO is iron, the one from AUTOHAUSAZ is aluminum), and gravity bled the slave cyl. Works fine now, BTW, the one removed was aluminum the one installed was iron. Since my problem only occured after being parked for a short period, there is probably a heat soak issue. Could it also be the pressure plate is going away?
