Title: clutch pedal
Post by: BradGTV on December 22, 2011, 11:51:10 AM
in my 89 75 TS, the clutch pedal has no 'fluid' pressure and the clutch will not dis-engage. (only the spring loaded pressure of the pedal itself) will bleeding the clutch system fix this? (fluid resivour is full and air shouldnt get into the system) or does the clutch mastercylinder or clutch slave need replacing?
cheers, Brad (no experience with hydro clutches)

The easy way to find out is to bleed the slave cylinder to get the air out of it and see how long the stroke of the slave cylinder piston - pushrod is, look up the specs, if the stroke is ok then look at the clutch fork for bending, if stroke of slave cylinder is lacking, look for rebuild of 1st slave cylinder, if still no good, look at rebuild of master cylinder, do the easy fixes and checks first, Colin.

Air can be induced into the system due to the master cylinder running low on fluid, on a Alfasud or 33 the clutch master cylinder uses the fluid from the brake master cylinder, so when you run low on brake fluid, you loose the clutch before the brakes, which is not a bad idea, Colin.

If your lucky bleed the it clean and top it up with new fluid and may be ok. Or it could have a air leak in the line. Another thing i did was pull the slave off and pull it a part and give it a clean ( it was full or crap in it) and then put back on, work a charm.
