The EBC Redstuff DP32137C is a rear pad set for the 2.0-litre turbocharged Mercedes-Benz CLA45 AMG (C117). The manufacturer describes Redstuff as a copper-free compound built from aramid fiber with ceramic granules, and it says the formula contains zero steel fiber, which it identifies as the cause of brake dust and fast rotor wear. The manufacturer also credits a high friction formula with a 15% brake effect improvement. For a buyer who wants stronger street stopping than the factory pad, cleaner alloys, and gentler disc wear, this is a more capable choice than a generic low-cost replacement. Search terms this part answers include CLA45 AMG rear ceramic pads, C117 low dust brake pads, and copper-free EBC Redstuff rear pads.
The manufacturer says the pads include Nucap NRS hooks on backplates to totally eliminate the chance of pad debond, which matters when you push the car through repeated hard stops. Pad replacement on this platform requires a step many owners don't expect: hold the call button and OK button for 5 seconds, scroll to pad replacement and hit OK, which rewinds the electronic e-brake so you can safely compress the wheel cylinder for rear pad replacement. Application years differ between sources, so confirm fitment against your VIN with the manufacturer before ordering.
Yes. Owners on user forums report that the electronic parking brake must be retracted first through the instrument cluster's pad replacement function, and that the handbrake should be released before you start.
Application year ranges differ between sources, and I could not confirm a single authoritative range from the manufacturer during research. Check your VIN-level fitment with the manufacturer before ordering.
The manufacturer describes the pads as low dust because they contain no steel fiber. Owners on user forums typically compare them favorably with the factory semi-metallic pads for cleaner wheels.
Rear pad replacement on the CLA45 is a moderate DIY job for someone comfortable with calipers. Owners on user forums report needing a 13mm wrench to remove the caliper and a 17mm to hold the inner guide bolt, plus an E18 Torx socket for the guide bracket. A clamp or piston tool is useful for pushing the piston back, and you will need to take the brake fluid reservoir cap off when pushing the pistons back in. Expect the job to take a few hours. Confirm the electronic parking brake is released before you start, and do not pump the brake pedal while the caliper is off, since one owner reported a parking brake that would not retract afterward.
