How do you bleed the hydraulic clutch on a 1990 4WD Chevy Cheyenne pickup?

Answer 1

Start at the m/cyl and loosten the line and pump THE PEDAL ONE TIME then tighten it and release the pedal then pump it ONE time again and keep this up until no air comes out. Then go to the bleeder screw on the slave cyl and do the same thing. It takes longer to just pump it one time but when you pump multiple times, it mixes the air in the fluid. Sometimes it is extremely hard to get the air out of clutches.

If that dosent work take the cap off your m/cyl then gow down to your slave/cyl and push the rod in and that will push the air out to the top.

You will see bubbles com to to the top do it until it stops then you should have peddle.
