front brakes torque spec question?

walkabout · 11-05-2007, 10:42 AM

Hello everyone,

I am doing front brakes/rotors on 03 325xi and need to know the torque specs for caliper bolts and slide pins. Thanks for replying.

sorry I have no personal experience with this and therefore do not know the torque specs that you need. However, maybe you will have better luck in the DIY/tuning section? Look under one of the stickies (the threads that are locked on the site by moderators for their information/ease of use)

I'm sure if you search around you can find the guide pin specs. I want to say it is 54 ft/lbs but that is a guess, I never use a tq wrench on those.

From the Good Book:

caliper to brake pad carrier mounting bolts: 22 ft-lbs.
brake rotor to hub mounting screw: 12 ft-lbs.
pad carrier to front steering arm: 81 ft-lbs. (what a pain!)

and, for completeness:
pad carrier to rear trailing arm: 48 ft-lbs. (rear brakes only!)
