Selecting the correct caliper for the specific mounting location is crucial for:

• maintaining the correct geometry of the braking system,
• ensuring even wear of brake pads and discs,
• maintaining predictable vehicle behavior during emergency braking.

Technical characteristics and compatibility

As an item from the Brake calipers and carriers category, the product has been designed to work with the factory Mercedes braking system. The caliper design is adapted to standard mounts, which facilitates installation and reduces the need for additional modifications.

Its original origin ensures:

• compliance with factory braking system performance parameters,
• proper fitment with the hub, disc, and brake pads,
• preservation of factory rear axle braking force characteristics.

The product has an assigned OEM part number and interchangeable numbers, which facilitates verification of compatibility with a specific vehicle equipment version and allows a mechanic to quickly confirm compatibility.

Condition, functionality, and practical application

The caliper is offered as a used part, which provides a favorable compromise between repair costs and maintaining the manufacturer's original specifications. This type of component is particularly recommended for:

• post-accident rear axle repairs,
• mechanical damage or corrosion of the existing caliper,
• the need for a quick replacement of the element to restore full brake efficiency.

Choosing an original, used caliper allows you to reduce the risk of fitment issues that may occur with aftermarket replacements of uncertain origin.

Benefits of using an original brake caliper
