XYZ Racing Hollow Rear Brake Kit — Mercedes Benz E CLASS W124 SEDAN (1986-1995)

The W124 carries real mass over its rear multi-link axle, and the factory rear discs were sized for a saloon Mercedes assumed would spend its life cruising autobahns rather than chasing apexes at a modern track day. As these cars move into restomod and fast-road territory, often with M104 straight-sixes or V8 swaps asking more than the original brief allowed, the standard rear setup becomes the limiting factor under repeated heavy stops.

The XYZ Racing Rear Big Brake Kit for the Mercedes Benz E Class W124 Sedan tackles that directly. It pairs a larger two-piece rear disc with a fixed multi-piston caliper, restoring front-to-rear balance on a chassis built to last but never built to stop like this. Specify it for the 1986-1995 W124 you actually drive hard.

What this brake kit does for your 1986-1995 Mercedes Benz E Class W124 Sedan

On the road you will feel a firmer, more progressive pedal as the larger rear disc and stiffer caliper cut the flex that creeps into a thirty-year-old braking system. Under harder use, a loaded hill descent or back-to-back stops on a fast B-road, the rear axle does more of the work, pulling heat and fade pressure off the fronts so the whole car settles rather than nose-diving. The hollow-vane disc trims unsprung weight at the rear, which the W124’s multi-link suspension rewards with cleaner body control over mid-corner bumps. With three pad compounds, Street, Sport and Racing, you can match bite and temperature range to how the car is used, from gentle classic duty to genuine circuit heat.

About the Hollow rear brake kit

The Hollow rear brake kit takes its name from the disc itself: a vented two-piece floating rotor with a lightened, hollow vane structure that sheds weight and draws heat out of the friction surface faster than a solid factory disc. It runs a fixed multi-piston caliper in place of the sliding single-piston design Mercedes originally fitted, clamping the pad more evenly and resisting the taper wear that plagues tired original calipers. Three pad compounds are offered: Street for quiet, low-dust road use, Sport for spirited fast-road work and the odd track day, and Racing for sustained track temperatures, so the kit suits a W124 used as a daily classic through to one built for track days. The caliper is hollow-bodied as standard, with an optional Hollow Racing version for serious circuit use that drops the dust cover, is rated to 1000C and carries a two-year warranty. Calipers come finished in Red, Yellow, Gold, Black or Anodized Black at no extra cost, with a Custom Color in any Pantone shade and premium polished-forged or candy finishes available, letting the view behind the wheel sit as discreet or as loud as the build deserves.
