1990 GMC Sierra clutch

Hi there,

bleed the master cylinder first, take of the pipe and press pedal, have someone block out let with a finger and release pedal, don't remove the finger till the pedal is fully up, do this 3-4 times until fluid ids flowing, if it wont the master is faulty, if you get fluid, re attach the line and complete the bleeding at the slave.
