Pelican Technical Article:

Parking Brake Shoes Replacement

Nick Czerula

Time:

2.5 hours

Tab:

$300

Talent:

***

Tools:

5mm long allen wrench, 6mm Allen bit, 6mm, 12mm deep sockets, socket set,

Applicable Models:

BMW X5 (2000-06)

Parts Required:

Parking brake shoes and hardware, brake cleaner, brake grease

Hot Tip:

Do one side at a time so you have an assembled side for reference

Performance Gain:

Proper parking brake function

Complementary Modification:

Flush brake fluid and replace brake rotors and pads

The parking brake is a drum system that is integrated into the rear brakes. The rear rotor hub flange acts as the drum and the brake shoes are mounted to the backing plate. The parking brake shoes can fail, linings can fall off and create a grinding noise. The hole where the retaining clips mount can also rust and fail. When this happens, the retaining clips pull through and parking brake shoes come in contact with the brake rotor when driving. If this happens, you will need to replace the backing plate, brake shoes, hardware and rotor.

Loosen wheels studs while the vehicle is on ground. Do not remove the studs yet. Lift and support the rear of the vehicle. See our tech article on jacking up your vehicle.

Remove the rear wheels.

Working in the vehicle interior, lever the top of the parking brake boot up using a plastic prying tool.

Then pull up the parking brake lever.
Figure 2

Then pull up the parking brake lever. Now carefully put forward pressure on the upper part of the released boot to clear the tab (green arrow). Pull the boot up and over the parking brake handle.

Check that the parking brake lever is in the released position.
Figure 3

Check that the parking brake lever is in the released position. Then release the cable tension using a 6mm deep socket to back off the 6mm locking nut and a 12 mm deep socket to back off the 12mm adjusting nut (green arrows).

Using a flathead screwdriver, slowly press the brake caliper piston in.
Figure 4

Using a flathead screwdriver, slowly press the brake caliper piston in. This allows the brake caliper to be pulled off the brake rotor more easily. I like to pry between the outer brake pad and brake rotor. This way there is less chance of damaging the caliper piston.

Working behind the brake caliper, remove the two 16mm brake caliper bracket mounting bolts (green arrows).
Figure 5

Working behind the brake caliper, remove the two 16mm brake caliper bracket mounting bolts (green arrows). The bolts can only be seen when viewing from behind the shock. They can be accessed and removed in the space directly behind the caliper. Remove the brake caliper with the bracket from the wheel carrier and hang it up using a piece of metal coat hanger or a strong bungee cord. Do not allow the caliper to hang from the brake hose.

Next, using a 6mm Allen bit, remove the brake rotor mounting fastener (green arrow).
Figure 6

Next, using a 6mm Allen bit, remove the brake rotor mounting fastener (green arrow). Then remove the brake rotor from the hub.

Next, unhook the return spring (green arrow) next to the adjuster from the parking brake shoes.
Figure 7

Next, unhook the return spring (green arrow) next to the adjuster from the parking brake shoes. I like to use an old pair of diagonal cutters with worn out cutting jaws. Grab the spring, pull it down and unhook it from the brake shoe.

Using a long 5mm Allen wrench, remove the parking brake shoe retaining clips by rotating it 90° and pulling it away from the brake shoes.
Figure 8

Using a long 5mm Allen wrench, remove the parking brake shoe retaining clips by rotating it 90 degrees and pulling it away from the brake shoes. Each shoe has one clip (green arrow).

Remove the parking brake shoes from the vehicle and then separate the remaining parts.

Remove the parking brake shoes from the vehicle and then separate the remaining parts.

Inspect the shoe adjuster.
Figure 10

Inspect the shoe adjuster. Check that it moves freely and is not damaged.

Then lightly grease the brake shoe to backing plate contact points (green arrows).
Figure 11

Then lightly grease the brake shoe to backing plate contact points (green arrows). This photo shows rear contact points. Apply grease to the area for the front parking brake shoe also. Install new brake shoes in the reverse order of removal. Install the brake rotor and brake caliper. Adjust the parking brake once the wheels are installed and tightened. See our tech article on parking brake adjusting.
