What It Helps Address

• Rear brake pad wear during routine brake service
• Squealing or noise from worn rear pads
• Reduced braking response from depleted friction material
• Uneven rear brake performance caused by aging pad surfaces
• Service replacement needs on Mercedes-Benz CLA250 and GLA250 rear brakes

Installation Notes

Confirm rear axle fitment before ordering, since BC1646 is for rear brake applications only. Inspect rotors, caliper condition, and pad contact surfaces during installation, and replace worn hardware as needed using the included mounting and abutment hardware. Verify the vehicle’s brake wear sensor setup, as this pad set does not include a wear sensor.
