What This Rotor Helps Address

• Rear brake pulsation caused by worn or uneven rotor surfaces
• Brake noise related to rotor wear or surface corrosion
• Reduced braking consistency from rotor thickness variation
• Rust buildup on exposed rotor surfaces
• Service replacement for worn BMW rear brake rotors

Installation Notes and Tips

Verify rotor dimensions, bolt pattern, and rear-axle fitment before installation. Clean the hub mounting surface thoroughly to help prevent runout concerns, and inspect pads, calipers, and hardware condition during brake service. The coated surface helps resist corrosion on non-friction areas, while the non-directional finish supports normal brake bedding procedures.

Quality Assurance

ATE brake parts are backed by Continental Automotive Systems’ OE brake manufacturing experience and are produced to a higher standard than conventional replacement parts. The SP20154 rotor reflects that engineering approach with coated protection and OE-focused construction for select BMW rear brake applications.
