Anyone know where you can find a good calipers for a reasonable price?

All the places I checked are out and waiting for cores.

Can't you rebuild your existing caliper or is it too far gone? If the piston bore is in good shape, you should be able to clean it up, put in a new piston and kit and be good to go.

When I was switching my car over to 88 brakes I was able to get a right rear caliper (Fully rebuilt) from Centric....Called their Tech line and they found the parts and assembled one for me.

As a suggestion, these parts are getting hard to find, and yet they have to be rebuilt every so often....When you see a Fiero in the JY go grab some SPARE calipers off of it and then, when you need to rebuild the caliper, you will have a spare to send off while still able to drive the Fiero (I actually have grabbed 2 sets of 88 calipers that I am holding for the Golden Gate Fiero club)

The threads where the line goes in is stripped. It we can’t find anything we will try a Helicoil. Did some checking this is a common issue on aluminum calipers and even Baer brakes says an heilicoil is an approved repair on their calipers.

Cores are scarce for the 84-87 cars. 88 brakes calipers are easy to find.

Do you mean the banjo bolt? I've seen helicoils used for that repair before. I'd suggest taking the caliper off so you can make sure that the coil goes in square. Also, Think about rebuilding the caliper to make sure you flush out all the swarf you're likely to get when you drill the hole for the helicoil. (Suggest that you rebuild both at the same time. The fronts are pretty easy and the kits are pretty inexpensive.)

I'm sure I don't need to tell you but when replacing the brakeline, always use new copper crush washers. Some folks have tried to "cheap-out" and use the old washer. Usually you get a leak and when you tighten the bolt you wind up with a stripped hole. (guess how I know this...) :-)

Mike, did you anneal the old copper washers before re-using? I'm among those who like to "cheap-out" ... and I've never had a problem with re-used copper crush washers.

Yes I will pull off my only real concern was finding a coil that was the right size as not to give me too little copper to cover. Also I expect to clip the coil as it will be longer than the hole.

I put a steel braided line on and the hose went into the index notch and I did not check the off set on the block going to the caliper. It was my bad as I should have looked. It was not a major off set so I missed it,

Yes new washers!

Found a used caliper for back up if needed.

No. That's where I screwed up. But I now keep a handfull in the parts bin. I never throw the old ones out, though, so if I ever run out I have some to anneal and reuse.

Emory cloth and new bolt with washers corrected the issue on the leak.

I think the paint just eats up the rings in the caliper and prevented them sealing.

I got the intake back on and the car fired up for the first time in over 20 years. It appears to be running well.

When copper washers are used they can get hard then don't seal very well. Annealing "softens" the copper so you can reuse it. To anneal the washer, I use a MAP gas torch to heat the washer to a cherry red colour. I keep it at that temp for a couple of minutes and then I drop it into a pan of room temperature water. When it can be picked up with your bare hands, the process is complete. The washer is now "soft" and ready to be used. (BTW, "soft" is a relative term.)

Others may do it differently but this has worked for me..
