Apply to all Chevrolet Luv with hydraulic clutch, this is a problem that all mechanics have after performing this repair.
PROBLEM: When changing the clutch kit the pedel of it does not work
solution: bleeding of the system, the correct form first, take out the pump and bleed pipe, while someone covers the hole in the pipe with their finger, another gives the pedal but not to the back That the liquid falls, let stand and the liquid returns to the deposit, after this the auxiliary cylinder is bleeding until the air and the pedal magically recover the precion,
this occurs because the piston of the pump loses the position and with this its work. Good luck and passance for this problem.
