The clutch master cylinder in my Fiero died last week and now I have to replace it. I think I might have an idea on how to do it but any advice anyone from someone with experience would be greatly appreciated.How to replace the clutch master cylinder in an 86 Fiero?Disconnect the negative (-) battery cable.
Disconnect the cylinder pushrod at the clutch pedal.
Disconnect and plug the hydraulic line at the master cylinder.
Remove the nuts attaching the cylinder to the cowl, then remove the cylinder.
To install:
Position the cylinder pushrod through the cowl and loosely install the cylinder-to-cowl nuts.
Connect the cylinder pushrod to the clutch pedal with the spring clip.
Tighten the cylinder-to-cowl nuts to 13 ft. lbs. (17 Nm).
Connect the hydraulic line to the master cylinder and torque it to 13 ft. lbs. (17 Nm).
Fill the clutch master cylinder with the recommended fluid.
When the hydraulic portion of the clutch system has been opened, air enters the system and has to be removed before proper operation can be restored. Use the following procedures to bleed the clutch hydraulic system.
Fill the fluid reservoir directly from a can of unused Delco Supreme No. 11 brake fluid or equivalent. Do not use the old fluid because old fluid is contaminated with moisture and dirt which may damage the hydraulic system.
Remove the floor mat or any other object that may obstruct the full stroke of the clutch pedal.
Unscrew the bleeder screw at the slave cylinder enough to allow fluid to be pumped out (1/2 - 1 full turn).
Push the clutch pedal down through the full stroke.
Have an assistant close the bleeder while the pedal is still fully extended. Allow the pedal to return quickly to its stop (with the bleeder Closed).
Repeat this procedure until no air bubbles can be seen in the fluid.
