XYZ Racing Hollow Rear Brake Kit — Mercedes Benz CLS 500 C219 (2004-2010)

The C219 CLS 500 carries the better part of 1.8 tonnes and was built to hold three-figure cruising speeds across a continent, which is exactly the duty that bakes the heat out of a standard rear brake. The XYZ Racing Hollow Rear Brake Kit for the Mercedes Benz CLS 500 C219 (2004-2010) swaps that softening factory rear end for a two-piece floating disc and fixed-caliper setup sized for repeated hard stops from speed.

This is the rear half of the braking equation, the axle that settles a heavy four-door coupe and keeps the balance honest as you wash off pace. Paired with the right pad, it brings the rear of the car up to the standard the front already needs on a GT this fast and this heavy.

What this brake kit does for your 2004-2010 Mercedes Benz CLS 500 C219

The two-piece floating disc cuts rotating and unsprung mass at the rear hub, so the axle reacts faster and the brake responds with less lag the moment you lean on the pedal. A fixed caliper clamps the pad evenly across its face, which holds a firmer, more repeatable pedal than the sliding factory unit once temperatures climb. Three pad compounds let you match the car to its job: Street for ordinary road use, Sport for harder fast-road driving and the odd track day, and Racing for track sessions where the rear needs to take real heat without fading. On a car as heavy as the CLS 500, that thermal headroom is what stops the second and third hard stop feeling longer than the first.

About the Hollow rear brake kit

The kit is named for its construction: a two-piece floating disc whose friction ring rides on an alloy bell, machined to shed weight from the disc itself while keeping the swept area needed to scrub speed off a heavy saloon-coupe, and to grow with heat without warping. It runs a hollow-body forged multi-piston caliper as standard in place of the factory single-piston slider, giving more even clamping and a stiffer assembly under load. Painted calipers ship in a choice of 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, so the rear hardware can be set off against the wheel or kept discreet behind it. Pad selection is the tuning lever here: the Street, Sport and Racing compounds change bite and heat tolerance without altering the rest of the kit. Built as a direct fit for the C219 rear axle, it is engineered to lift braking consistency on a chassis that spends its life carrying weight at speed.
