BMW 34216864900 Ventilated Brake Disc

Firmly block the front wheels, then raise the rear of the vehicle and support it securely on jackstands. Remove the appropriate rear wheel. Release the parking brake. Inspect the disc. Removal: Remove the brake pads. Remove the bolts and remove the caliper mounting bracket. Discard the bolts; new ones must be installed. Loosen and remove the brake disc retaining bolt. It should now be possible to remove the brake disc from the stub axle by hand. If it is tight, lightly tap its rear face with a plastic mallet. If the parking brake shoes are binding, check that the parking brake is fully released. Fully release the parking brake cable tension to obtain maximum freeplay in the cable. Insert a screwdriver through one of the wheel bolt holes in the brake disc, and rotate the adjuster star wheel on the upper pivot to retract the shoes. The brake disc can then be removed. Installation: Ensure that the mating surfaces of the disc and hub are clean and flat. Align the marks made on removal, and tighten the disc retaining bolt to the specified torque. If a new disc has been installed, use solvent to wipe any anti-corrosion preservative coating from the disc before installing the caliper. Ensure the disc mounting surface on the hub is free from dirt and corrosion. Slide the caliper into position over the disc, making sure the pads slide pass either side of the disc. Tighten the caliper mounting bolts to the specified torque. Install the wheel, then lower the vehicle to the ground and tighten the wheel bolts to the specified torque. Adjust the parking-brake shoes and cable. Depress the brake pedal a few times to bring the brake pads into contact with the disc. Bleeding won't be necessary unless the brake hose is disconnected from the caliper. Check the operation of the brakes carefully before driving the vehicle. Recheck the parking brake.
