I have a BAER brake Pro touring Brake set up that I bought for another car I was building a few years back , a 51 Chev with a fatman f/e and a 9" ford RE,, It has 12 " rotors on the rear and 13 " on front,, and I was using MM2 front spindles,, with 16 " wheels on the front and 17 on the rear

BUT!!! I sold the 51 and kept the brake kit,,

NOW !! I am building a Anglia Thames , and had planned on using the brake set up on it,, both the F/E and R/E has the same mounting as the 51 did,, but I am using 15" wheels on the Thames,, so the rotors are a little too large, and the calapers are a real tight fit to the rim,, I could probably trim a little off the edge of the Calipers,, but before I dio that I was Wondering if I put the rotors on my lathe and cut the edge down about 1/4 " all around,
What would I have to do to the mounts?? cause the mounts would keep the calapers in the same position regardless of how much I cut the rotors down,,

Any ideas out there..????
