Vehicle Application and Placement

The presented brake caliper is designed for installation on the rear left side of the vehicle. This placement is crucial for correct brake force distribution and vehicle stability during intense braking, especially on slippery surfaces.

Selecting the correct caliper for the specific side of the vehicle minimizes the risk of incorrect installation, facilitates the mechanic's work, and helps maintain the original brake system geometry.

Technical Characteristics of the 42/20 Caliper

The designation 42/20 refers to a specific caliper configuration used in selected BMW E87, E90, and E91 models. This type of construction ensures appropriately calibrated pad-to-disc clamping force, resulting in stable, predictable braking during everyday use.

The caliper works with the vehicle's rear braking system, integrating the function of the service brake with the operation of other system components. This allows for consistent system performance, including electronic aids responsible for traction and stability control.

Benefits of Using an Original BMW Caliper

Choosing a brake caliper dedicated to specific generations of BMW 1 and 3 Series allows for the preservation of operating parameters intended by the vehicle manufacturer. The most significant advantages include:

• compatibility with the original brake system design,
• proper fitment with the caliper bracket, pads, and disc,
• maintenance of predictable braking characteristics,
• reduced installation issues due to correct vehicle placement.

For workshops and users, this means a lower risk of incompatibility and easier diagnosis of potential future faults.

Application in Service and Repairs

A used brake caliper of this type is suitable as a replacement part in case of wear, seizing, or mechanical damage to the existing component. It is a practical solution for repairs such as:

• standard brake system inspections,
• rear axle post-accident repairs,
• servicing vehicles used extensively in urban traffic.

Selecting the correct caliper for the specific BMW model and mounting side allows for reduced repair time and minimizes the need for additional modifications.
