rear brembo conversion issue

[baldydaz]

for all of us on here that have done the brembo REAR brake conversion i think i've found an issue.

i fitted my rear calipers a couple of weeks ago with some mintex 1144 track pads.
last friday i did a track day at donington park. after the trackday i checked the brakes etc and found the pads had worn very unevenly. ie the leading edge (bottom) of all 4 pads on the rear were worn almost to the metal while the trailing edge (top) was hardly touched.
if it had been one pad i'd have thought stuck piston/stuck pad etc, but due to it being all 4 worn in the same way........hmmm

now, hopefully a solution.
the calipers on the m3 are mounted at the rear of the wheel. on the porsche they came off they are mounted on the front of the rear wheel.
so the calipers on the m3 are mounted on the wrong side.....
i think the pads have worn this way due to the different size pistons in the calipers.

so, what we need to do is strip the calipers, remove the link pipe from the 'bottom', turn the calipers over, swap sides, swap the bleed nipples from bottom to top then fit the link pipe to the bottom. (we may need to make a new link pipe as the original sits in a recess in the caliper)

this will put the larger piston at the top of the caliper, hopefully curing the wedgy pad problem.......
