Detroit Axle Brake Caliper Bracket Rear Right Phenolic Piston R18B5031

Description

Product Overview

The Detroit Axle rear right brake caliper bracket is engineered as a direct replacement for original equipment, offering a precision‑fit mounting platform for the brake caliper assembly. Constructed from high‑strength steel with a corrosion‑resistant coating, the bracket provides a solid anchor point that resists deformation under heavy braking loads. The integrated phenolic piston, measuring 2.00 inches in diameter, delivers smooth, consistent pressure to the brake pads, reducing pedal travel and improving overall stopping distance. Designed to meet or exceed OEM part number R18B5031 specifications, the bracket incorporates reinforced bolt holes that align perfectly with factory‑drilled mounting points, eliminating the need for additional modifications. Each component undergoes rigorous impact, wear, and fatigue testing to verify durability in demanding environments, and the product is backed by a 10‑year limited warranty that underscores Detroit Axle’s confidence in its engineering quality.

Usage

This caliper bracket is intended for use on the rear right wheel of a range of light‑truck and SUV models that share the same mounting geometry. It is ideal for both professional automotive technicians and experienced DIY hobbyists who require a reliable replacement part during routine brake service, component upgrades, or after‑market performance modifications. The bracket’s phenolic piston material offers superior heat resistance, making it suitable for vehicles that experience frequent stop‑and‑go traffic, mountainous driving, or towing applications where brake temperatures can rise sharply. Installation is straightforward: the bracket bolts directly to the factory‑mounted caliper mounting points, and the piston slides into the caliper housing without the need for additional adapters. After installation, the brake system should be bled according to the vehicle manufacturer’s specifications to remove any trapped air and ensure optimal pedal feel. Regular inspection of the bracket and piston for signs of wear, corrosion, or cracking is recommended during scheduled maintenance intervals to maintain peak braking performance.

FAQ

What vehicles are compatible with this rear right brake caliper bracket?

The bracket is designed for a range of light‑truck and SUV models that share the same rear‑right caliper mounting pattern. Specific fitment information can be found in the Detroit Axle fitment chart, which lists the exact makes, models, and years that correspond to part number R18B5031. If you are unsure whether your vehicle is covered, you can enter your VIN on the retailer’s website or contact our support team for confirmation.

Do I need to replace the brake pads when installing this bracket?

While the bracket itself does not require brake pad replacement, it is highly recommended to inspect the pads for wear during any brake service. Installing new pads at the same time as the bracket ensures optimal contact with the phenolic piston and maximizes braking efficiency. If the existing pads are within wear limits and in good condition, they can be reused, but a thorough cleaning of the caliper bore and piston surface is advised.

How does the phenolic piston differ from a standard steel piston?

Phenolic pistons are made from a composite material that offers excellent thermal stability and lower friction compared to traditional steel pistons. This results in reduced heat buildup during prolonged braking, less piston wear, and a smoother pedal feel. The material also resists corrosion, extending the service life of the caliper assembly, especially in environments with high humidity or road salt exposure.

What is covered under the 10‑year warranty?

The warranty covers defects in material and workmanship for a period of ten years from the date of purchase. It includes replacement of the bracket or piston if they fail under normal operating conditions. The warranty does not cover damage caused by improper installation, misuse, aftermarket modifications, or normal wear items such as brake pads and hardware. For warranty claims, retain your original receipt and contact our support team with the part number and a description of the issue.

Can I install this bracket myself, or do I need a professional mechanic?

The bracket is designed for straightforward installation with standard hand tools. If you have basic mechanical experience, access to a lift, and the appropriate torque specifications, you can complete the replacement yourself. However, for safety and optimal performance, many owners prefer to have a qualified technician perform the installation, especially if additional brake system components need to be serviced at the same time.
