Fits Mercedes Benz C CLASS W204 C 350 (2007-2014)

Brake pad compound

Street: quiet, low-dust, strong cold bite for road driving. Sport: higher temperature range and more bite for fast road and occasional track. Racing: maximum fade resistance for sustained track use (noisier and dustier cold). Match the pad to how hard you actually brake.

Disc size

Caliper grade

Hollow is the standard caliper: a lighter hollow-body forged caliper with a dust cover and a 5-year warranty. Hollow Racing drops the dust cover for sustained high-temperature use (rated to 1000°C, 2-year warranty) — the track-grade choice.

Caliper colour

Painted colours are included. Polished-forged finishes are mirror-polished forged calipers (Titanium, Gold, Silver); candy colours are a deep, mirror-reflection paint. Both are premium upgrades — fuller detail further down the page.

Disc style

Drilled discs (cross-drilled holes) vent gas and water and look aggressive; slotted discs (surface grooves) wipe the pad face clean and resist fade under sustained hard use. Same price — choose on looks or how you drive.

Centre bell

The centre bell is the CNC-machined aluminium hat that joins the disc to the hub. Standard anodized is included; a two-tone bell adds an anodized accent ring in your choice of colour; titanium is the lightest, forged option.

Carbon-ceramic rotor

Carbon-ceramic rotors are a special-order track upgrade: far lighter than steel, fade-resistant at extreme temperatures and extremely long-lived. The price follows the disc size you choose above. The standard two-piece steel rotor is included.

XYZ Racing Hollow Rear Brake Kit — Mercedes Benz C CLASS W204 C 350 (2007-2014) — 330 mm
330 mm

The W204 C 350 carries its 3.5-litre V6 well forward of the front axle, and Mercedes tuned the standard car for refinement rather than repeated heavy stops. On a rear-wheel-drive saloon of this weight, the back axle does more of the stopping work than most owners assume, and the factory rear setup is usually the first thing to fade once you start using the performance the C 350 genuinely has.

This rear big brake kit for the Mercedes Benz C CLASS W204 C 350 (2007-2014) is aimed squarely at that weakness. Supplied as a matched pair of rear calipers and discs, it restores bite and pedal consistency at the rear of the car, with a choice of pad compound so the kit matches how hard you actually drive – from settled road use to sustained circuit sessions.

What this rear brake kit does for your 2007-2014 Mercedes Benz C CLASS W204 C 350

The first thing you feel is a firmer, more progressive pedal that holds its travel when the brakes get hot, rather than going long after a few committed stops. Three pad compounds – Street for quiet, low-dust running, Sport for fast road and the odd track day, and Racing for sustained circuit work – let you set rear bite to suit your use, which matters on a rear-driven W204 where rear brake behaviour shapes how stable the car feels under trail-braking into a corner. The two-piece floating discs use hollow vanes to carry heat while trimming rotating mass, and stronger, more fade-resistant rear braking takes some thermal load off the front discs, so the whole car copes better with repeat heavy use. Included caliper finishes – Red, Yellow, Gold, Black and Anodized Black at no extra cost – let the kit sit behind the wheel as cleanly as it works.

About the Hollow rear brake kit

The XYZ Racing Hollow rear brake kit is built around two-piece floating discs whose hollow-vane construction cuts rotating and unsprung mass at the back axle without giving up thermal capacity. Less mass spinning at the rear hubs helps the suspension settle faster over poor surfaces and eases the load the dampers have to control. The kit pairs that disc design with a fixed caliper, hollow-body as standard, and a compound choice that runs from a clean, low-dust Street pad through a Sport pad to a full Racing compound for track work; a Hollow Racing caliper upgrade rated to 1000C with a two-year warranty is offered for cars run hard on circuit. The Street and Sport options keep the C 350 civil for daily and fast-road driving, while the Racing compound is there for owners who run the car hard and need rear bite that survives heat. Included caliper finishes run Red, Yellow, Gold, Black and Anodized Black at no extra cost, with a Custom Color in any Pantone for £150, plus premium polished-forged Titanium, Polished Gold and Polished Silver and candy Teal, Blue, Red and Orange. Discs come drilled or slotted at the same price, with two-tone centre bells in five anodized colours or titanium selectable at checkout. It is a bolt-on rear upgrade rather than a full re-engineering of the braking system.

Choosing your spec

Every kit is built to order around the choices you make above. Here is what each option actually changes, so you can spec yours with confidence.

Brake pads — Street, Sport or Racing

Every kit ships with a full set of high-performance pads; the compound is your call.

Street is the right default for fast-road driving — a strong, progressive cold bite with low noise, low dust and long disc life. Sport raises the working temperature and adds bite and fade resistance for hard road use and the occasional track day, while still behaving on a cold morning. Racing is a track compound built for sustained abuse: huge fade resistance and bite once heat is in it, at the cost of more noise and dust when cold. Match the pad to how hard you actually use the brakes — there is no benefit to a race pad that never gets up to temperature.

Caliper grade — Hollow vs Hollow Racing

Hollow is the standard caliper on every kit: a hollow-body forged caliper, lighter than a solid one, fitted with a dust cover and backed by a 5-year oil-leak warranty. For most fast-road and spirited track use it is all the caliper you need.

Hollow Racing is the track-grade upgrade. It runs the same hollow body but without a dust cover (so there is nothing to melt at sustained high temperature), uses a twin-metal piston that isolates heat travelling from the disc to the oil seal, and is rated to 1000°C. Available 330–356mm (rear). Warranty is 2 years on oil leaks and 10 years on appearance. Built for professional racing and repeated track days.

Caliper colour & finish

Painted colours (Red, Yellow, Gold, Black, Anodized Black) are included at no cost. Want an exact match to your car? Custom Color (+£150) paints the calipers to any Pantone code you supply (15–20 day lead time).

Polished Forged finishes are the flagship: a forged caliper given a mirror-polished surface treatment that shifts colour with the viewing angle. Beyond the looks, the polished surface dissipates heat better, resists rust and stands up to the weather. Choose Titanium (neochrome, +£350), Polished Gold (+£300) or Polished Silver (+£250). They look their best paired with a titanium centre bell. Care: clean only with a dilute neutral cleaner or water.

Candy colours (+£200) use a deep candy-paint and polishing process for a mirror-reflection, boutique finish — pick Teal, Blue, Red or Orange (shown below right).

Centre bells

The centre bell is the CNC-machined aluminium hat that joins the disc to the hub. The standard anodized centre bell is included. The Two-tone bell (+£200) adds an anodized accent ring — choose Red, Yellow, Orange, Purple or Silver right here at checkout. The Titanium centre bell (+£500) is a forged titanium bell (bolts not included) that finishes off the polished-forged look.
