Big brake kits that fit the Mercedes-Benz GLS
For the Mercedes-Benz GLS (X167, 2019–2026), front kits come from AP Racing, Akebono, Alcon, Brembo and TTSPORT with 6-piston, 8-piston or 10-piston calipers; rear kits come from AP Racing, Brembo and TTSPORT with 4-piston calipers. On this car we recommend 355–420 mm front rotors and 380–410 mm rear rotors.
Every GLS kit is a street kit, with rotors in high-carbon steel or carbon ceramic. Most sit on brackets made for this car; the exception is an OEM-style direct-mount kit that bolts to the factory caliper mounts. Some bracket kits are built around genuine Mercedes-AMG, Cadillac, Ford or Audi calipers made by Brembo or Akebono.
With the rotor we recommend for this car, the smallest front kit needs 18-inch wheels and the others 19 to 21 inches; rear kits also need 19 to 21 inches. Spoke shape and offset change what actually clears, so send us your wheel details if you are unsure.
