	Assuming the Return spring is still in place (refer workshop manual.).. If this car uses cable actuation, then either replace the cable, or remove it from the vehicle (refer workshop manual), and lubricate the cable either by "wicking" light machine oil or automatic transmission oil,down between the cable and sheath. Ensuring that the cable is free in movement before refitting. Note: "Wicking" a bowden style cable is a long process, it will take you several hours to achieve. Alternatively, if your car uses a hydraulic system, you will most likely need to replace the slave cylinder (refer workshop manual). You will find the piston in the slave cylinder is suffering from a build up of muck and crud. If you like you could rebuild it replacing all the rubber components however you may find that corrossion has attacked the cylinder walls such that replacement is the better option. __________________ There are two reasons for a man to do a thing, One that sounds good, and the real one...

	Welcome to the insanity. What has changed since the car worked correctly? By slow do you mean that the clutch grabs higher, or is it actually not following your foot's movement? __________________ Bob

	Once it has engaged, does it slip at all when going up hills? If not, then it is just a matter of freeing up the linkage, which I suspect (but don't remember if I ever knew) is hydraulic. Once is is freed up, make sure that it is adjusted so that you have 1" of pedal travel before you feel any real resistance (from trying to release the clutch). __________________ Si hoc signum legere potes, operis boni in rebus Latinis alacribus et fructuosis potiri potes!

	Ordinarily, the clutch engages when the pedal comes up, and releases by pressing the pedal to the floor. Bob asks a good question: do you mean that the pedal is sticky and doesn't follow your foot, or that the clutch engages at a point too close to the top of pedal travel? __________________ Si hoc signum legere potes, operis boni in rebus Latinis alacribus et fructuosis potiri potes!

	When I was younger, I worked in a service station that had a truck with a hydraulic clutch. As it would wear, the clutch would start to engage while your pedal was pressed down. It was not to bad if you had a little room under the pedal, just push it further down and pull it into neutral. If not, just hold the brake a bit harder. ( First gear was a very low "granny" gear.) __________________ Bob

	My very first car was an 1957 MGA, purchased for $75 in running condition. The previous owners thought the clutch was "shot." As you can imagine, a quick look under the hood revealed the problem in a couple seconds. A 35 cent seal had me on the road in no time. I had a motorcycle (a 1943 Indian) in which the clutch was disengaged by a ball-and-ramp mechanism in the side cover. The aluminum case supporting the mechanism had cracked, so the cover would flex too much to disengage the clutch. I rode it this way for most of a year, until I could afford to get it welded. A good solid foot push forward would enable the tranny to be slipped into first gear (via tank shifter), and I was good to go. There were false neutrals between each of the three gears, so it could be shifted easily and quietly with a little care. Uphill starts were tough. __________________ Si hoc signum legere potes, operis boni in rebus Latinis alacribus et fructuosis potiri potes!

	thats funny bob i can relate. i cut a square piece of carpet out so the clutch pedal would push in that much farther. it was a 1984 f-350 dually. You can some times buy a bit of time if you bleed the slave cylinder like you would do breaks. You could also have a few week or broken fingers on the pressure plate. what the heck buy a new BMW that one is 36 years old.time for a new one. where can i pick up your old one. __________________ anyone can F--*#@% up a design.It takes a good Man to fix it.
