Low-Met Rear Brake Pads

Brembo P50138 is a rear disc brake pad set built for Mercedes-Benz applications that use the TRW brake system. This Premium Low-Met OE Equivalent Pad is formulated for quiet, smooth braking with cleaner wheels and consistent performance in everyday driving.

Designed for Mercedes-Benz AMG GT 53, AMG GT 43, CLS450, E450, E53 AMG, E63 AMG S, GLC63 AMG, GLC63 AMG S, E400, and E43 AMG rear brake applications, Brembo P50138 matches the fitment and friction profile expected from an OE-style replacement. The Low-Met formulation is ECE-R90 approved and uses a premium shim to help reduce noise.

Key Features

  • Low-Met friction material for balanced braking performance.
  • Premium shim helps promote quiet operation.
  • Formulated for cleaner wheels and smooth pedal feel.
  • Prepared for wear indicator integration.
  • Fits TRW brake system applications.

Detailed Fitment and Design

Brembo P50138 uses a Low-Met compound developed for North American driving conditions while staying aligned with OE-style expectations for European vehicles. The pad dimensions measure 129 mm wide, 70/79 mm high, and 17.4 mm nominal thickness, with FMSI 9277-D2047 identification. This part cross-references PowerStop 17-2047 and Raybestos Brakes PGD394AM for the same application.

Common Issues This Part Can Address

  • Brake noise during normal stopping.
  • Uneven or reduced rear brake response.
  • Dust buildup on wheels from pad wear.
  • Need for an OE-equivalent rear pad replacement.
  • Wear indicator service requirements on supported applications.

Installation Notes and Tips

Verify TRW brake system fitment before installation. Confirm the rear pad shape against FMSI 9277-D2047 and check rotor condition, caliper hardware condition, and wear indicator setup during service. Fitment includes Mercedes-Benz rear applications such as 2017-2025 AMG GT 43 and AMG GT 53, 2018-2021 E63 AMG S, and 2019-2023 CLS450 and E450.
