Purpose and vehicle placement

The presented caliper is designed for installation on the rear right side of the vehicle, which is crucial for the correct distribution of braking force on the rear axle. The design of the housing and guides is adapted to work with a disc of a specific thickness and diameter, which allows for maintaining the correct piston stroke and even pressure of the pads against the disc's working surface.

The offside (O/S) placement means that the caliper has been developed with a specific orientation relative to the hub and control arm, which minimizes the risk of improper installation and facilitates servicing of the braking system.

Technical characteristics and design

The AMG series caliper housing is designed to withstand high thermal and mechanical loads typical of dynamic driving. The applied body geometry ensures:

• stable guidance of brake pads in the carrier,
• adequate rigidity during repeated braking cycles,
• effective heat dissipation from the area around the disc and pads.

Thanks to this, the Mercedes R231 AMG Brake Caliper Brake Housing Rear Right O/S allows for maintaining consistent braking force and reducing the phenomenon of fading during intensive use. Its original origin from the Mercedes group helps maintain factory operating parameters, including the correct pedal travel and even pressure distribution in the rear circuit.

Condition, verification, and service application

The item comes from the Brake calipers and carriers category and is offered as a used part, which allows for cost-effective repair of the braking system while maintaining the manufacturer's original specifications. This type of component is particularly useful for:

• post-accident repairs of the rear axle,
• damage to threads, guides, or the body of an existing caliper,
• regeneration of the braking system using the original housing.

Before installation, a standard service procedure is recommended: checking for leaks, the condition of working surfaces, threads, and guide elements, as well as replacing consumables (seals, dust boots, pads, and discs) in accordance with the vehicle manufacturer's recommendations.

Benefits of using an original AMG caliper

Using an original caliper on the rear right axle allows for maintaining the consistency of the entire Mercedes R231 AMG braking system. The main advantages include:

• Factory fit – compatibility with suspension and hub geometry, without the need for mounting modifications.
• Predictable braking parameters – maintaining the operating characteristics designed by Mercedes engineers.
• Possibility of integration with existing braking system equipment, such as lines, carriers, or sensors, according to the specific vehicle configuration.

For workshops and service centers specializing in the Mercedes brand, such an element is a practical solution for repairs where maintaining the original technical specification and compatibility with other system components is key.

Choosing a used caliper and additional materials

When choosing a used brake caliper, it is particularly important to match it to the specific body version and braking system. It is worth paying attention to the compatibility of the placement on the vehicle, disc type, and system configuration. To better prepare for the purchase and installation of elements from this group, a guide describing the principles of safe selection of brake components will be helpful – you can find it in the article Second-hand braking system: how to safely choose discs, calipers, and ABS?.
