Bracket for larger rear rotors
Does anyone else other than ed miller make caliper brackets to run larger rotors on 10-bolt with pbr's? After upgrading my fronts to c4hd brakes I want a larger rear rotor to balance out the look, and the extra surface area couldn't hurt with stopping as well.

Re: Bracket for larger rear rotors
I'm not sure what rotor Ed uses, but typically the rear brackets are quite easy to design for those calipers since the e-brake is built in.
What size rotor were you thinking about?

Re: Bracket for larger rear rotors
Baer Brakes makes brackets for at least 13" rotors. Some of their kits use the PBR caliper in the rear but you would have to call to see if they will sell them separate. They have them for both 9 and 10 bolt rears.

Yup. The bracket is no problem. The big question is what 13"x0.8" rotor are they using? I have found no such beast in my searching.

Their own custom rotor. One guy here has them, I have seen his pics here. It's a 2 pc rotor. eradispeed+

Re: Bracket for larger rear rotors
I'm not sure. Somebody has mentioned to me in the past that FlynBye offers a 13" rotor for the PBR rear brakes. I have not confirmed this myself. I would assume that would be a 1pc rotor.

Re: Bracket for larger rear rotors
I'll have to do some research on the baer stuff, and see what parts are available. I really would prefer to keep everything stock gm parts if possible. I want everything to look stock. That's why I would really like to stick with pbr's.

Re: Bracket for larger rear rotors
Do you happen to have a part number for the rotor? I would rather no buy from ed unless I have to. My last transaction with him did not go well at all.

Re: Bracket for larger rear rotors
I don't have the part numbers as they were part of a complete kit. If you call Baer Brakes they should be able to get you what you need. They are easy to deal with.
