Purpose and function of the element

BMW 1 3 E87 E90 F20 F30 Rear Hand Parking Brake Shoe Supporting Ring Plate acts as a support for the parking brake shoes on the rear axle. Responsible for:

• precise guidance of the brake shoes within the drum in the brake disc,
• maintaining the correct geometry of the handbrake system,
• stable transmission of forces when applying the parking brake.

As a structural element of the braking system, it influences the even wear of the linings and the repeatability of the handbrake operation in everyday use.

Construction and technical features

This brake shoe support disc was designed by BMW to be specifically tailored to the specific suspension and rear axle brake architecture. The design includes:

• dedicated mounting points for the steering knuckle or rear hub,
• holes and sockets for adjustment elements and jaw springs,
• shape adapted to the working diameter of the parking brake shoes.

The used element retains the factory geometry, which facilitates assembly and allows for correct positioning of the shoes relative to the working surface of the drum in the brake disc.

Condition, origin and service use

This part is offered as a used part, sourced from a dismantled BMW vehicle. This choice is beneficial in situations where:

• it is necessary to replace a damaged or corroded support disc,
• you repair the parking brake system after a mechanical failure,
• you restore the efficiency of your brakes after the vehicle has been stationary for a long time.

The low declared mileage of the donor translates into limited wear and tear, which makes the element an attractive alternative to new substitutes of uncertain quality.

Benefits of using the original support disc

Using the original BMW parking brake shoe support disc provides a number of practical advantages:

• Factory fit – dimensional compatibility with the rear axle hub and steering knuckle facilitates installation and minimizes the risk of problems with handbrake adjustment.
• Stable operation of the parking brake – correct shoe guidance promotes even pressure on the drum and repeatable operation of the brake lever.
• Support for further repairs – a solid mounting base facilitates subsequent replacement of the shoes, springs or cables without the need to interfere with the supporting element.

For workshops and private users, this means a predictable repair result and reduced risk of repeat intervention in the same area of the braking system.

Selection, compatibility and service knowledge

When selecting a parking brake shoe support disc for a BMW 1 and 3 Series, it's crucial to verify compatibility with the specific body generation and rear brake system type. The following are helpful:

• manufacturer's markings on the part itself,
• comparison of the shape and mounting points with the dismantled element,
• consultation with the BMW parts catalogue or a specialist workshop.
