How to remove Rear Brake Disc Rotor on 2005 BMW 325?


Brake Disc (Rotor)


Removal & Installation




NOTE
The brake rotors on M3 models are directional rotors and different from side to side. To differentiate from side-to-side, the left side brake rotor part number ends in an odd number, the right side rotor part number ends in an even number.


WARNING
The balancing clips in the venting of the rotor must not be moved or removed. This will cause an imbalance of the rotor.

  1. Block the front wheels.
  2. Loosen the rear wheel bolts 1 / 8 of a turn.
  3. Raise and support the rear of the vehicle. Remove the rear wheels.

NOTE
Do not loosen or disconnect the brake caliper fluid hose. Once removed, support the caliper assembly with mechanic's wire to avoid damaging the line.

  1. Remove the brake caliper as outlined in this section.
  2. Remove the brake caliper bracket as outlined in this section.
  3. Remove the special, shouldered recessed hex fastener using a 6mm hex socket. If the fastener is corroded in place, spray it with a penetrating lubricant and use a hand impact driver to loosen.
  4. Remove the brake rotor. If the brake rotor is seized in place:
    1. Loosen the brake rotor retaining bolt about 3 turns.
    2. Spray a penetrating lubricant around the rotor-to-hub seam.
    3. Install two wheel bolts approximately 10 turns and using a suitable hammer, rap sharply on the flat surface of the flat wheel-to-brake rotor-to-hub surface. DO NOT contact the machined area of the brake pad-to-rotor surface. The shock from the impact should eventually loosen the brake rotor from the hub.

To install:
  1. Check the rotor and replace as necessary.
  2. If a new rotor is to be installed, make sure the rotor is free of any protective coatings. Remove the protective coating as recommended by the manufacturer.
  3. Clean the hub and brake rotor surfaces, then before installing the brake rotor, apply a very light coat of an anti-seizing compound.
  4. Install the brake rotor retaining fastener and tighten to 12 ft. lbs. (16 Nm).
  5. Check the parking brake adjustment and adjust as necessary as outlined in this section.

WARNING
The shouldered brake rotor fastener must be reinstalled. If damaged or missing, replace. Failure to install the fastener could result in the lug bolts being sheared off during hard braking.

  1. The balance of the installation is in reverse order of removal noting the following.
  2. Install the wheels and hand tighten the lug bolts. Lower the vehicle carefully until the tires begin to contact the surface and torque the lug bolts to specification in a crisscross pattern to 66-81 ft. lbs. (90-110 Nm).

CAUTION
Failure to properly torque the wheels to the correct torque using the proper sequence could cause a brake pulsation and rotor warpage.

  1. Burnish the rotors by making 5 full stops from 30 mph (50 km/h), then allow the brakes to cool. Make 5 additional stops from 30 mph (50 km/h) and allow the brakes to cool again. This will burnish the rotors and allow full braking efficiency.
  1. Raise and safely support the vehicle. Remove the tire and wheel assembly.
  2. Disconnect and support the caliper, using a piece of wire.
  3. Remove the mounting bolts and remove the brake rotor with the proper tool.
  4. Always replace both discs of the same axle.
To install:
  1. The installation is the reverse of the removal procedure. Adjust the parking brake.
The parking brake must be broken in after replacing the rear brake discs. This is done in the following steps:
  1. Step 1-5 complete stops from 30 mph
  2. Step 2-Allow the brakes to cool off
  3. Step 3-5 complete stops from 30 mph
