2012 X3 Rear Brake Question

ourlife85 · 02-13-2022, 11:50 AM

While replacing rear brake caliper I released the caliper pressure by using the T-45 to turn clockwise.
My question is once I have the caliper back on do I need to tighten the T-45 back counter clockwise? Or does pumping the brake tighten itself?

I don't recall having to tighten anything back in. That section is part of the electric parking brake. For peace of mind you might want to set and release it.

You do not. That is the electric parking brake and will screw itself back in when you set the brake.
