If you're interested, you can still buy New Old Stock OEM front and rebuilt rear calipers.

Rebuild kits are available from most auto parts stores. Rock Auto stocks them. They don't inlucde the slider pins. Rock Auto also sells a "Caliper Guide Pin" kit separately.

Ayup NAPA didn't carry them the last time I went to buy them but they sold rebuilt ones for almost a hundred bucks each, WTF whatever happened to rebuilding these things yourself, it really isn't that hard or require expensive specialty tools to change a few seals and clean up the walls of the caliper the piston slides in and out of. Worst case you have to rent or borrow a honing tool you can use on a drill. Hell you can borrow them from most parts stores for a deposit that you get back when you return the tool.

Just make sure the walls of the piston and caliper are not rusted to crap and they are almost all rebuild able.

Good luck

Steve

i had the guy at calipers online rebuild my rear calipers, and bought 2 ac delco rebuilds on ebay. i have my original fronts still as they didnt require a core, i wanted to rebuild them myself, i have rebuilt the 84-87 calipers, they are super easy to rebuild. do you know if the slider boots are included in the kits to rebuild the 88's?

I recently used the Fiero Store rebuild kit. You can buy the boots separately. If you look for my thread there is a link in there to an excellent DIY post that explains how you take apart the piston. Mine was full of gunk, perhaps yours is too.

Here is an excerpt from my recent rebuild adventure ...

So gang, the rebuild kit arrived. Here is what I discovered:

1) The sliders were actually OK, at least they slide manually with the same effort before/after my cleaning and lubing.

2) The piston air valve DID have fluid behind it, indicating a bad piston, a la Ogre Cave. With the piston out the caliper bore was chockablock full of sediment and sludge ... it really looked bad. Sorry, in my zeal to clean and rebuild I didn't get a picture of the sludge. By far the worst I have ever seen. I think this solves the mystery of the stuck caliper.

So, I used Incomutt's excellent procedure w/pictures to take apart and clean the piston and replace the seals. The only part you don't get in the kit is the inside piston seal, which if bad would give one the leaky piston air valve. Since the seal and the mating surface looked OK and felt smooth I decided to 'go for it.. I have flushed the Line with fluid and believe I should do the other lines and rebuild those calipers as well -- they must also be filled with sludge and crap, although the other three seem to work fine.

Here's the Link: http://www.fiero.nl/forum/A...110502-2-101129.html
