PBR Calipers? What year is best?

[boat]

Yeah, yeah, I have done some research and I have some questions.

The PO of my 94 MTX gave me a box with the Mustang PBR calipers, brackets, and new pads in it. One of the calipers has a busted bleeder screw, a bolt is in its place.

I am wanting to just take the calipers in to say, Advance Auto Parts and turn these that I have in for cores and just get some nice new reman'd ones that have all the new hardware and such.

What I am wondering is there a year in the 99-04 Mustang calipers, where there is one that is best or doesn't work as well for this mod? I search on Advance, they have calipers from 99-02, then 03-04, listed seperately.

Also, is there any modification to be done to the SHO brake lines if I get the brake lines that go with the Mustang calipers?

There's more than one flavor of PBR calipers. The desirable units were on, IIRC, 94 Cobras and Corvettes of the same era. Of them there are two different bore sizes, with the most common (and most suitable for a stock SHO master cylinder) having 38mm pistons.

There's also a lighter duty PBR unit that people have used on SHOs but isn't as suitable for track or other heavy-duty use.

I'm running 04 Mach 1 calipers w/40mm pistons, and everything is cool .

The PBRs that you most likely have are from mustang GTs and V6s 99-04. As far as i know there is no real difference in any of them, and they should work fine for you.

That's a good point. Are you sure you have the Cobra PBRs and not the GT PBRs?

I have the GT PBR Calipers.

Oh, I gots no clue bout those.

Kelvin - I believe boat has the aluminum calipers that have the cooling fins on them, and use a different Mustang bracket which has a pronounced "****" in the bracket like the DN5/DN101 brackets.

[K-Dawg]

Yeah, I just don't know about any changes that were made.

Those are the ones made to go over the 10.8" rotors. So if you had a 94-95 SHO, you could bolt those on to the stock spindles and use the stock rotors. They cannot be made to work with Cobra rotors just by swapping the brackets, they go with the 10.8" rotors only. OEM for 99 - 04 Mustang V6 and GT.

Others that have used the PBR caliper/95 OEM rotor combination state that the setup is just as effective as the 96 upgrade, and has better fade-resistance when tracked.

Oh, and the setup weighs less than the 96 upgrade.

 

[fast Ed]

The MN12 T-Bird / Cougar guys have pretty much found the same thing. The PBR calipers a lot more pad surface than the 96 upgrade calipers.

I don't think those are cooling fins, rather there for strength.

 

[Storm-Chaser]

You're correct, but most people who don't know about the "spreading" issue with this earlier PBR design, are more likely to recognize the "cooling fins" than "reinforcing-ribs".
