84-87 Rear Caliper rebuild (Page 2/3)

Where did you buy the rebuild kits? The Fiero Store gets $12.00 each for the rear and $6.50 each for the front.

Oreilly's, but my son was working there at the time I wrote this so I got a good discount. The price you quoted it about right....

Sure wish he was still there.... saved me hundreds of $ on my rebuild... Also goes to show the markup on auto parts...

I see now.... I just had a revilation. I didn't understand where the little check valve button was. (You had me confused when you said it was behind the pad) How does the piston come apart so that I can get to the button. Thanks, Scott

After doing some more research, it appears that I have recalled pistons that do not have the 2 way valve behind the pads. That is what the little bleeder hole is for. I just hope that the piston doesn't leak. If I have to get new pistons, I might as well get the rebuilt calipers, and I will have all of this time trying to rebuild them. This sucks, but now I know.

Dodgerunner- Great writeup...as usual. Has anyone done the same for 1988 rear calipers?

Thanks Dodgerunner. Great threads! (front & back)

How easy is it to mess this job up?
What do I look for to determine whether my pistons/bores are in rebuildable condition?

The hardest are the rears due to the e-brake screw. Getting the piston back in takes some care.
As far as the pistons and bore you don't want score marks on the piston sides indicating they where running with side loading very much.otherwise they will leak if it's where the seal runs.
On the bores you don't want to see scoring or pitting from water in the walls.

The rear caliper is covered in my cave. I didn't bother with rebuilding info for a few reasons.

Understand that:
1. If there is fluid in the piston, it is leaking internally and cannot be repaired. Don't bother with new caliper seals if the piston is leaking out the weep hole. (Later pistons have a weep hole on the side instead of the piston face.)
2. Even if the piston isn't leaking, it's probably bad and the Ebrake and self adjustment are unlikely to be fixed by this.

The piston is a crappy design in either version. 88 uses the same piston system BTW.

Hi, reviving this dead thread. It seems I am a bit late to the party since not many people are working on fiero's as much as the 2010's lol.

I'm working on a set of rear calipers after the E-Brake seized the calipers when I pulled it. (Who knows how long it's been since it was last pulled). Had usual rust issues, but the biggest issue with my calipers was tons of dirt (not metal) in both cylinders. One has a good boot but bad rear seal, both pistons and screws are good. The passenger side was a different story however. It had white milky crap all over the spring and walls, as well as a glob of what can only be described as a loogie in the cylinder (It was almost like bearing grease). The dirt problem was only worse on this side since the dust seal was ripped from the ring. Unfortunately there is a small nick in the outside of the cylinder bore that I think will cause me to have to get a new caliper. I want to replace the dust seals ideally, but I cant figure out how they are attached to the caliper. There seems to be a hard rubber ring that seats into a groove, but no amount of pulling will help it come out. I tried using a tool to take out this ring and its like its fused with the metal.. I can only scape off tiny uneven chunks, leaving behind some in the groove. Is there an easy method to pulling out these dust seals?
