XYZ Racing Hollow Rear Brake Kit — Mercedes Benz C CLASS W206 C CLASS (2021-2026)

The W206 C-Class put on weight in the place that punishes brakes most: over the rear axle. The move to 48-volt mild-hybrid running gear across the range, and a rear-mounted battery on the C63 S E Performance, leaves the back end of this generation doing more braking work than any C-Class before it, and constantly blending regen with friction. The XYZ Racing Hollow Rear Brake Kit for the Mercedes Benz C CLASS W206 C CLASS goes straight at that problem with a lighter, more thermally honest rear corner that keeps its bite when the electronics hand braking back to the pads.

This is a rear-axle upgrade built around two-piece floating discs and a fixed caliper, offered with Street, Sport and Racing pad compounds so the back end can be matched to how the car is actually used: daily miles, committed fast-road driving, or repeat circuit sessions in a heavy saloon.

What this brake kit does for your 2021-2026 Mercedes Benz C CLASS W206 C CLASS

The two-piece floating disc design strips rotational and unsprung mass from the rear hubs, which the W206 feels as a cleaner turn-in and a slightly quieter ride over broken surfaces. A fixed caliper clamping a larger swept area gives a firmer, more linear pedal than the sliding-caliper rear setup most of these cars leave the factory with. Step up to the Racing compound and the rear holds temperature through back-to-back stops instead of greasing off mid-session. The Street compound is the sane choice for a fast-road W206 that still sees the school run, with bite from cold and manageable dust, while the Sport compound bridges the two for harder road work and the odd track day. Across all three, brake balance stays predictable as the car shifts weight rearward under trail-braking.

About the Hollow Rear Brake Kit

The caliper is a hollow-body forged unit as standard, lightened internally without giving up the stiffness it needs under load, and it clamps a two-piece floating disc whose friction ring can move on the bell as it heats and cools. A multi-piston layout spreads the load evenly across the pad for consistent clamping force. Three pad compounds cover the spread of intended use: Street for refined road duty, Sport for harder road and occasional track, and Racing for sustained high-temperature circuit work. Painted calipers come in Red, Yellow, Gold, Black or Anodized Black at no extra cost, with a Custom Color in any Pantone for a small upcharge and premium polished-forged or candy finishes if you want the kit to stand out. Serious track users can specify the optional Hollow Racing caliper, rated to 1000C and backed by a two-year warranty. The focus throughout is repeatable rear-axle braking and reduced thermal fade on a platform that asks a lot of its rear brakes.
