I was originally keeping an eye out for decent condition and priced E82 135i brembo setup but they are either poor condition or silly money, also as they are getting on a bit as well ive decided im going to be using calipers from the newer M135 models
Front is fairly straightforward and the M135 Fronts are 4piston caliper and use a 340mm x 30mm discs (compared to my 130i single piston 330mm x 24mm discs) and im told both discs and calipers are a direct bolt on for the earlier Exx cars, will be doing that soon as ive just received some good condition front brakes from BP on here thanks
Rears are little more tricky and as far as im aware nobody has been able to get these fitted onto earlier E8x cars, the M135i Rears are a 2 piston caliper using 345mm x 24mm discs ( 130i has single piston caliper with 300 x 20mm discs) so a lot bigger than 130i setup!, now from what information ive been able to get the calipers "should" bolt onto my rear hubs with just some small modications for clearance, that may not be required yet but until I get calipers I don't know for sure, looks like a small chamfer on edge of mounting lug is all that's needed, fingers crossed!
Rear discs wise is more complicated and why its not a simple swap, firstly M135 rear discs use smaller internal handbrake shoes so while they should slip onto hub flange looking at data but they wont go over the larger handbrake shoes from E8x models, after trawling though my disc data sources there a few different discs from various models of bmws that could possibly work and its just a case of working which way to go, im not confident I need 345mm rear discs so may go little smaller with a custom pad, but until I get calipers and get chance to prove that I can bolt them on with minimal fuss ive not ordered anything.
Couple of pics below of front setup ive just received from BP
, rears ive got coming from another member on here and told they will be posted today so hopefully get this week, fronts will be going on very soon and rears I will have a tinker once they are here.
