Product Details

This DFC brake kit is engineered for rear service on 2017-2019 Mercedes-Benz GLS550, 2014 Mercedes-Benz GL450 with the Sport Package, and 2013 Mercedes-Benz GL550. The GEOSPEC rotor coating helps resist rust better than conventional paint or zinc finishes, while the machined surface and balance inspection support consistent pedal feel and quieter operation. The 5000 Advanced pads are formulated for stable friction performance and are assembled with premium shims to help reduce brake noise.

Part number 4502-63224 is a practical choice for drivers and technicians looking for a rear brake job on a Mercedes-Benz GLS550 or GL-Class vehicle with matched rotor and pad components in one kit.

What This Brake Kit Helps Address

• Rear brake pulsation from worn or uneven rotors
• Squealing or noisy braking from aged pads
• Reduced stopping performance from worn friction material
• Rust buildup on exposed rotor surfaces
• Longer service time from separate rotor and pad sourcing
