PBR calliper rebuild Kit

[GaborVincer]

I am in need of a part number for a calliper rebuilt kit that can take the track day abuse. I have melted off the dust boot and this causes the pistons to get dirt in them. I just want a kit that will take the heat.

Any suggestions.

Anyone that has raced or open tracked their Mustang that used the PBR caliper has had the same problem. I raced my 93R for a few years and the boots burned off as well. I never worried about it except when I needed to install new brake pads. I then used brake cleaner to flush out the piston before I pushed it back into its bore.

This dust in the short run does no harm but it left there can lead to the pistons sticking in their bores. I know that almost all racing calipers do not have dust boots but they are serviced and/or checked frequently.

If yours is a street car then one thing you can do is to service your brakes after a track event by cleaning the caliper pistons then reinstalling the pads.
In fact you should be using a race compound pad for on track driving and switching back to a street pad for normal driving.

One other thing you can do is to install a piece of stainless steel or titanium, the same shape as the brake pad backing plate between it and the pistons.
It acts as an additional heat sink which disapates the heat some before it gets to the caliper pistons. Also are you running brake cooling ducts?

How thick would you make the spacer?
Colling ducts I don't use due to it being a daily driver.
I did find through PBR a rebuild kit but us guys in Canada don't have the same network of suppliers as in the US.

The thickness would need to be no more then 18-16 gauge SS steel. Even aluminum would work, it just wouldn't hold up as long due to it's softness so you would have to make new ones as they deform due to the force of the pistons on them.

The spacer would act as a heat shield as well as a heat sink.

You might consider removing the splash shields to allow more air to the back of the rotors & the caliper. Ford did this on some models of the Mustang. The only downside to doing this is that if one were to drive their car down a steep mountain road in the rain and really heat up their brakes and then drive through a puddly of water it may cause problems with the rotors, The key word here is "May". The other thing is the inner seal of the wheel berings will be exsposed to more dirt and water. Under normal conditions I don't think thats a problem but if one lives in a rural area with dirt & garvel roads then it could.

Don't want to sound stupid :beatdeadhorse:but with the steel are you saying SS as in stainless steel

[Jim B]

Yes, I do mean stainless steel. I used "ss" for short. If you can find titanium and here's is one source, it's an even better metal to use then SS. I'm not sure they ship to Canada though?

Hate to admit it, but of course the PBR were used on Chebies, too.
I got mine from local Chevrolet dealer. And yeah, the boots don't last for racing or even track days.
