cholmes1 said:Has anyone found any solutions to the rear brake noise? It appears to be somewhat mixed in those that have it and those that don't, but would like to know the best/quietest pads and rotors to apply during installation. For reference there will be 98% street use and maybe 2% track use on the system.
Thank you for the help.
KNS Brakes said:Not singling you out - just pointing out a common request we get. As far as noise goes - street pads are usually quiet and track pads are not. Well bedded pads/rotors are more quiet than those that are not and light braking is usually louder than hard braking. Race pads will 'unbed' if used cold or on the street a lot.

There is really no such thing as 'light track' You are either repeatedly braking hard (like on track) or you are not.
If you are getting noise from street pads - try bedding them a bit. Or flip them around and re-bed.

Bringing this thread back from the dead and seeking some additional input.
I currently have the Steeda 13" kit on the car, it went in before the GT500 solution was really readily available. Only 1 source for rotors and that's Steeda with their custom DBA rotor.
Since switching to Pagid pads front and rear, been having issues with the rear brakes. Moaning and calipers hanging up in reverse, grinding sounds on track with vehicle weight transfer under acceleration while turning (not during braking) and it's caused me to look into this some more.
Basically decided to go one of 2 directions.
GT500 brackets and GT500 rotors - 13.8"
Or
Go with something like the GiroDisc 11.8" rotors, but take advantage of it being a 2 piece design and significantly lighter. Giro Disc comes in under 10lbs, while a GT500 rotor pushes a little over 16lbs.
I have gotten good feedback on their durability.
Is the lighter weight and 2 piece design of the GiroDisc more advantageous than the perceived advantages of the larger rotor with more surface area of the 13.8" but a 1 piece design and heavier?
I am for now running Pagid RST-3 up front in factory 14" brembo and RS29 in the rear. Next change is a true race caliper in the front, but haven't decided on that one yet.
Any input from the experts here? Seems to me that lighter 2 piece floating rotors bring more advantages than the larger GT500 rotors with the brake bias being so heavily to the front. But that's my totally not an expert opinion from reading lots.
Before you make a wholesale change, check your rear pads; post a photo of the "centering pin" on the pad (that interfaces with the piston). I had one set of pads (albeit not Pagid) where the pins were too tall from the manufacturer and this caused the rear brakes to drag with no pedal applied. My "solution" was to file the centering pins down. Worked great. Might not be your issue but it's worth checking before you spend $$$.
I have run both the Pagid and Girodisc set up along with the GT-500 rears.
I find the GT-500 set up to provide better braking. The Girodisc set up was good, rotors lasted for ever but gave no noticeable improvement in brake feel.
I run the blowfish brackets.
If you are going the GT500 rear brake route, you only need the rotors and the brackets. The calipers are the same; although it would probably be worth looking over your calipers and seeing if they need to be rebuilt or not, assuming they are still the set that came on the car from the factory.Just read this whole thread. A lot of good info. I do have questions. I would like to do the GT 500 rear swap on my 06. Do I only need rotors and the Gt500 calipers? Or do I need calipers as well. Also saw a brief mention of rear brake cooling. I have never seen this done. Is it possible to see som pic? Pm on that would be fine.
Thanks, Dave

The GT500 calipers (like the BOSS 302 calipers) have a different part number simply because they are painted black; mechanically all the OEM rear calipers for S197 are the same (although there is some mention of a possible casting change in the link below--do your research).
Also here's a link to a "one-stop" shop for the conversion kit: https://vorshlag-store.com/collecti...7-mustang-13-8-gt500-rear-brake-upgrade-kit-3
Thanks for your input. I have seen that kit on Vorshlag's page before. I have also read he entire thread on their old Mustang. I had some apprehension about the rear calipers because that car was an 11'. Probably will order a set of calipers for the GT 500 and compare. Mine are close to being toast....not the good kind of toast either.If you are going the GT500 rear brake route, you only need the rotors and the brackets.
