88 rear calipers are just not available in the wild any more. I *still* owe my core back to The Fiero Store so someone else can have a right rear.

Texas requires that I have a working parking brake to pass inspection. That and the parking brake actually adjusts the rear calipers. I have no parking brake on either side and I suspect that the pawls are somehow toast. I have about 5 months to get this working correctly.

Anyone have insight on a workable alternative? It would be possible to do a lot of others if we could somehow make new castings of the hub bracket. A pipe dream of course.

Anyone ever tried to repair the parking break mechanism? I think I heard here that it is not possible to actually fully disassemble a rear caliper without doing major damage.

I have a trashed rear caliper that I think I will have a go at it perhaps soon. Did something stupid and ruined the caliper *and* the casting it bolts to. Talk about a red face!

OK. I just read further in the Forum and found the link to the Ogre's very excellent description. Now I knwo how they work, but I would guess we still will eventually need an alternative to the stock calipers!

I had my right rear start leaking inside the piston......Checked around and found that 88 rear calipers had dried up. So I called Centric's tech support line and talked to Pat.....He stated that although they no longer "Stocked them" he would see if they had enough spare parts to make up a caliper- They did and he had it rebuilt and delivered in a week.

They probably don't have any more spare parts- at least not enough to make up a complete caliper- but you could call and then send them yours and they could rebuild it. The critical detail on these rear calipers is the internal seal in the piston- there is a whole thread on Pennocks on replacing that seal ("1988 rear brake caliper piston seal found")....But, Ogre has brought up concerns of whether the piston can be taken apart and safely re-assembled so that it functions properly. I did one and it worked out OK- so far.

Either way, check on "Row 52" and if you see an 88 Fiero show up in a junkyard locally, go grab the calipers so you have spares- I did this and have 2-3 sets (Have to go count them again)- I am saving them for everyone in the Golden Gate Fiero Club...I have also offered them to the Fiero Store, if they run short.

Right now, Row 52 shows 1988 Fieros in Salt Lake City, Denver and Sherwood, OR......Anyone in the vicinity should go grab the calipers! (NOW!!!)

The rear calipers on the '88 coupes in Denver are gone. Someone beat me to them, but I did get some other nice parts.
I believe you can still get rebuilt rear calipers (as well as brand new front ones) from calipersonline.com

I also believe that places like Cardone will rebuild your caliper if you send it to them. The cost is pretty much the same and you do have shipping costs both ways, but it is still a viable solution (assuming they still do this).

Yes, Calipersonline shows them- but they may not have any stock. Still, I would definitely call....

Thanks, Wftb for posting the link to the rebuild info!

Wow!!! That post referenced on the rebuild is too awesome for words. I'll have to get parts and practice on my trashed caliper. Then I can rebuild the ones on Kevin's car.

You are welcome. I also have a link to new pistons from Raybestos but a few people have checked and they are no longer made.
