About this kit
A complete front big brake kit for the Mercedes-Benz GLC X253, Mercedes-Benz GLC X254, BMW 225L G42 and more. It uses two Endless MONO6 6-piston calipers and a pair of rotors (380 mm) in high-carbon steel or carbon-ceramic, plus pads, braided lines and mounting hardware.
We match the mounting brackets to your car. You'll need at least 19-inch wheels with enough room for the caliper. Not sure? Send us your wheel details.

All Endless kits →Common questions
Will it fit my wheels?
Big calipers need room inside the wheel. Check the minimum wheel size in the specifications. If you're not sure, send us your wheel make and size and we'll check.
Do I need new brake lines or fluid?
Braided lines come with the kit. You'll need fresh DOT 4 fluid and a full bleed after fitting.
Can I fit it myself?
If you're used to brake work and have a torque wrench, yes. If not, have a workshop fit it. Our installation page covers the basic steps and bed-in.
