130i to M135i Brake upgrade project

Post by THETYRANT » Tue Mar 15, 2016 8:16 am

Ok as my stock brake calipers are getting on 10years old I thought it was time to replace/upgrade them, im currently running our track pads in stock setup and while it works very well on road and track im conscious that these old calipers can start to give sticking issues with age, as I found on my last 130i so a good excuse to upgrade :D

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.

Front are easy enough and a few on here have done it without issue, so if you see some for sale at decent money snap them up :)....rears are the unknown but i hope to find a solution for that as well once i get calipers here.

I was eyeing up the M135 calipers which were for sale a while ago (I suspect the ones you have brought) but wasn't sure regarding the fitting so I too am very interested to see the result here :)

Good to see these parts going to good use for a fellow forum member.

Hope the rears work out without too much grief.


Anyone wanting a set of used OE M135i rear discs and pads off the same car [mine] - PM me. No lips on the discs and plenty of meat on the pads [14k miles according to idrive CBS] - looking for £150 cash and collect.

Front i bought wern't advertised i pm'd BP on here as saw he had upgraded to the bigger setup, rears ive got coming from Dan_88 on here and i believe he still has some fronts in for sale section, i nearly bought them as well but BP's had decent discs with his and looked a better condition so went with those, there are some delivery mileage ones in for sale secton as well, fronts as sensible price i think considering condition/mileage etc, but rears maybe a bit pricey for us as we cant use rear discs, genuine bmw discs are not cheap at well over £200 a pair for rears!

Nice easy upgrade fronts bolt straight up with the aid of a small wheel spacer, I went for the easy option with the rears and used the 135i setup 322mm x 22mm so a fair bit smaller than the m135i rears but still moving in the right direction + they look so much better than the old sliding calipers .

All bolts up nicely, and my braided hoses fitted and the original grub screen even went back in

Granted mine are the 370mm but the 340 are the same fitment

Ok fronts are on after work tonight, straight forward enough only thing I needed to do was a slight tweak/bend to rear stone shield plate that sits behind discs. it was just touching caliper body so just tweaked it out the way for clearance.

Had a quick road test to settle things in and bed pads and discs together again, brakes feel good even for stock pads, cant wait to get some of our XP pads in there :D

Pics below of before, during and after :)

First old setup

Then all off and hub flange cleaned up

Now new calipers and discs all fitted

Once ive got some miles on this setup and im happy with it I will be selling my part worn XP10 front pads for stock calipers, discs are nearly down to minimum though so not worth selling them on, will keep them and stock calipers in case I ever need to put car back to standard.
