Fits Mercedes Benz CLA C118 (INCLUDING 4 MATIC) (Rr Multi-Link Suspension) (2019-2026)

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.

Painted — includedTell us the exact Pantone (PMS) code you want the calipers painted.Polished forgedCandy
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 CLA C118 (INCLUDING 4 MATIC) (Rr Multi-Link Suspension) (2019-2026) — 330 mm

The C118 CLA carries its mass over the nose: a transverse engine and MFA2 underpinnings that load the front axle hard and leave the rear comparatively light. That balance is exactly why the rear brakes matter more than owners expect once power climbs. On a 4MATIC car, and especially the M139-engined AMG variants, the rear axle has to help haul the car down and keep it settled on the way into a corner. The XYZ Racing Hollow Rear Brake Kit addresses that end of the car directly.

Cut for the multi-link rear setup fitted to these C118s, this rear big brake kit pairs two-piece floating discs with a fixed caliper to firm up pedal feel and hold temperature through repeated stops. It is the rear-axle half of a properly sorted brake balance for fast-road and circuit use on the 2019-2026 Mercedes Benz CLA C118.

What this big brake kit does for your 2019-2026 Mercedes Benz CLA C118

Fit it and the first thing you feel is a firmer, more progressive pedal: a fixed caliper flexes far less than the sliding factory unit, so the bite is sharper and stays consistent as the disc heats. The two-piece floating disc trims rotating and unsprung mass at the rear, which helps the multi-link suspension track the road and keeps the back axle calmer under heavy braking. Three pad compounds, Street, Sport and Racing, let you match the rear’s behaviour to how you actually use the CLA, from a quiet commute to back-to-back track stops. On a nose-heavy 4MATIC car, sharpening the rear means you can lean on the brakes into a turn without asking the front axle to do all the work.

About the Hollow Rear Brake Kit

This is a fixed-caliper upgrade built around a two-piece floating disc whose friction ring rides on an alloy bell, stripping mass from the rotor while keeping a large swept braking area and absorbing heat expansion without distortion. The caliper is a hollow-body forged multi-piston design as standard, resisting the flex of a single-piston sliding OEM unit and turning more of your pedal effort into clamping force. Pads are offered in three compounds: Street for daily driving, Sport for spirited fast-road use and occasional track, and Racing for circuit sessions, so the kit scales with the car’s role. Painted calipers come in Red, Yellow, Gold, Black and Anodized Black at no extra cost, with a Custom Color in any Pantone for a small upcharge and premium polished-forged or candy finishes, which is worth thinking about on a CLA where the rear wheels are on show through open-spoke designs. As a rear-specific kit it is built to complement a front upgrade and set sensible front-to-rear bias rather than over-brake the lighter rear axle.

Fitment for the Mercedes Benz CLA C118 (2019-2026)

This kit is specified for the Mercedes Benz CLA C118, including 4MATIC versions, running the rear multi-link suspension, across the 2019 to 2026 model years. Confirm your car has the multi-link rear setup before ordering, as that is the configuration this rear brake kit is designed around.

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.
