Have any of you guys ever rebuilt calipers on a 65-67 (the 4 piston caliper). I was just going to buy new ones but they want me to put a mortgage on my house for them. Online they are cheaper but they want anywhere from $125-200 core deposit each, without any garuntee they will return your deposit (must be thier definition of rebuildable). Any suggestions or advice would be great.

 

I would try looking in some junkyards

 

20 years ago that was probably a good idea, but now any '67 in a junkyard will be probably in a Mustang junkyard and will cost close to new if in usable condition.

 

I was wondering about this myself. Do you know if you can buy a rebuild kit for them? With most calipers I've rebuilt in the past, I have bought a piston and seal kit for them, and lightly honed the cylinders. This has worked very well with the newer style single piston ones I have done. I guess if you pull them apart and find that they are very badly rusted in the bores, you will need to replace them anyway.

 

You can buy the seals and the pistons. I have always been lazy and just replaced calipers, but it looks like not this time.

 

Any idea of the cost of seals and calipers? I would have to assume this would be fairly reasonable. As long as the bores are in ok condition.

 

Seals are about$15-$20, I think pistons are in the $40 range (upgrade to stainless)

 

Any one who is recommending you rebuild your own four piston calipers has never done them before. They suck to do. Even when you think you have them right there is no guarantee that they will work right until you put them on and test them. The biggest pain is getting the old postons out. Trust me, spend the money, get rebuilt calipers. You will be better off.

 

Sounds like you have experience here. Just wondering why its any harder to do these 4 piston calipers over conventional single piston ones (other than obviously there are are 4 times the number) In the past, if im replacing pistons, I drill and tap a hole into them and make a jig up to pull the pistons out. Would this not work with the 65-67 type?

 

Single piston calipers can be taken apart by removing the caliper from the car and the using compressed air to blow the piston out of the bore. That usually works very well. On the 4 piston type you can only do that one time and then all the aire blows throught the bore with no piston in it. There is no way to blow the other three pistons out. Due to age and lack of maintenance a few pistons on these are usually stuck anyway. Since brake fluid atracts water the bore can get rusty and seize the piston. The calipers also come in two halves. There are seal between the two halves that should be replaced. I have tried breaking the 2 halves apart and then trying to grip the pistons and pull them out of the bore. That never worked well either. So any way you cut it they suck.
