Clutch Slave Cylinder Q. I recently replaced the clutch slave cylinder on my 1984 Isuzu Impulse. It seemed like a simple R&R job, but when I try to put it in reverse after it's been sitting for several hours, the gears grind and won't engage until I pump the clutch five or six times and then try it again. What did I do wrong? Thanks, David

A. Well David, it sounds to me like you didn't bleed the air out of the hydraulic system. A hydraulic clutch needs to be bled just like the brakes for proper operation.

To bleed the clutch have someone pump the pedal and hold it down while you open the bleeder on the slave cylinder. Keep doing this until there is no more air. Be sure to keep the clutch master cylinder full while you do this to prevent any more air from entering the system.
