Purpose and Fitment for BMW 1 Series

The presented caliper is designed to work with the rear axle on the left side in BMW E81, E82, E87, and E88 models. Its placement on the vehicle is clearly defined as rear – left side, which simplifies the selection of the correct component when replacing a single caliper or repairing the braking system on the driver's side.

By maintaining the original body design and mounting points, the caliper fits the original brackets and brake lines intended for these body versions. This allows for installation without the need to modify other system components.

Technical Characteristics of the Brake Caliper

The caliper belongs to the group of components responsible for transferring hydraulic force to the brake pad and disc, therefore maintaining the correct body rigidity and proper piston operation is crucial. The caliper design ensures:

• stable guidance of the brake pad in the caliper bracket,
• even pressing of the pad against the disc on the rear left side,
• correct cooperation with the factory BMW hydraulic system,
• serviceability (replacement of seals, guides, pads) in accordance with manufacturer procedures.

The 40/20 designation refers to the specific structural configuration of the caliper, characteristic of selected brake system versions in the 1 Series, which is important for matching a specific vehicle configuration.

Condition, Origin, and Service Application

The item comes from the BMW line and is classified as a used part, allowing for economical brake system repair while maintaining original specifications. This type of component is particularly useful in situations where:

• the existing caliper on the rear left side has seized or is leaking,
• the caliper needs replacement due to mechanical damage (e.g., pitting corrosion, thread damage),
• the braking system is being repaired after a collision or interference with the rear suspension.

Choosing an original caliper from this series allows for maintaining consistent braking performance between the left and right sides of the rear axle, which is important for vehicle stability during intensive braking.

Benefits of Using an Original BMW Caliper

By using the BMW E81 E82 E87 E88 Rear Left Brake Caliper 933 40/20, you gain a component designed for a specific BMW platform, which translates to:

• factory fitment to the hub, disc, and pads intended for the rear axle,
• maintaining predictable braking characteristics across the entire load range,
• easier diagnostics and servicing due to compliance with BMW technical documentation,
• the possibility of using standard bleeding and system adjustment procedures.

For workshops and individual users, this means simpler installation, a lower risk of compatibility issues, and maintaining brake system operating parameters at the level intended by the manufacturer.

Selection and Safety When Purchasing a Used Caliper

When choosing a used brake caliper, it is crucial to verify its compatibility with the specific body version, engine, and braking system. It is worth paying attention to:

• placement on the vehicle (rear, left side),
• type of caliper bracket and pads used,
• possibility of standard refurbishment (seals, guides, bleed screw).
