1999 BMW 328i (E46) – Rear Brake Servicing Part 2

Hey Everyone,

So this is the conclusion of the rear brake servicing on the 1999 BMW 328i sedan. Much of what we do in Part 2 is cleaning the dirty components and then reassemble them in reverse order to what we did in part 1. If you want to see how to clean the rust off pieces like the brake pad carrier connectors, check out the 2nd part of the brake servicing video we did on the Mk.4 Jetta last year that includes a segment on using a wire wheel. After reassembling the rotor and caliper, we then move on to putting the wheel back on. We show you the proper way to torque wheels, or really anything that has more than two bolts/nuts (the star pattern). Later this year we’ll release a video exclusively on changing your wheels.

Interestingly, while in the video you can see that the caliper still works well, we have no trouble pushing it in. We found afterwards that the brake is still dragging on this wheel, so we aren’t really sure what the problem is. My first guess is that the wrong pads were put on the car on this wheel, and so they’re too thick and will just drag indefinitely until they have wore down some. Another possibility is that there’s an issue with the brake line on this wheel, such that there isn’t enough vacuum pressure to pull the brake back in after use. And a final possibility is that the caliper is bad (possibly related to 2.) and will need replaced.
