How to Change Brake Pads and Wear Sensor on 2006 Bmw 525Xi

Article provided by wikiHow, a wiki how-to manual.

A brake job can be done in your garage at a fraction of the cost of a shop.

Steps

1. 1
   Obtain necessary parts (pads, rotors--whichever is being replaced) from auto parts store. Don't forget to place new sensor. Takes just one sensor for front, one for the rear.

   
   
2. 2
   Jack up front or rear, CHOCK wheels, and place jack stands for safety.
3. 3
   Remove wheel.
4. 4
   Look at the caliper (part that sits on edge of rotor, presses the discs against rotor). There is an anti-rattle clip on the front which will pop out with pressure applied by a screwdriver between the wheel hub and inside edge of the clip.
5. 5
   On the BACK side of the caliper there are two Torx bolts under black plastic caps about 1/2 inch round. Pop the caps out and you will be able to back out the bolts with a T-45 bit.
6. 6
   The caliper can now slide off of the rotor. Hang the caliper with a wire from the springs, so it's not hanging by the brake line to prevent a brake fluid leak. Let's just say you don't want that.
7. 7
   Take the old pads out and replace with the new ones. The brake pad wear sensor attaches to the inner pad on the passenger side (pay attention to how it is installed and clip the new one back in the same way). Attach the other end of the sensor to the harness which is in a protective box on the upper part of the wheel well.
8. 8
   Replace the calipers and tighten the Torx bolts back down.
9. 9
   This is a good time to rotate the tires. BMW doesn't recommend rotation, but my rear tires get extremely worn down on the inside over time.
10. 10
