Fits Mercedes Benz CLA 4 (2013-2019)

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 Front Brake Kit — Mercedes Benz CLA 4 (2013-2019) — 356 mm
356 mm

The C117 CLA 4’s MFA architecture means the front axle is doing most of the braking work before the 4MATIC system has even entered the calculation. Under sustained hard stops from motorway speeds, the geometry loads the front corners heavily, and the stock stoppers, adequate for the school run, acceptable on a fast B-road, begin to fade well before a track session ends or a committed Alpine descent is done.

This XYZ Racing front big brake kit addresses that front-axle demand directly. It is a matched pair of left and right calipers and two-piece floating discs. Hollow-vane disc construction sheds rotating and unsprung mass where the C117’s nose-heavy, transverse-engined layout places the most thermal load. Three pad compounds span quiet road use through to full racing specification, and the caliper finish options mean the hardware can be specified to work with whatever wheel sits outboard of it.

What this brake kit does for your 2013-2019 Mercedes Benz CLA 4

Hollow-vane disc construction reduces unsprung and rotating mass at the front corners. On a platform where the 4MATIC drivetrain and transverse engine arrangement already bias load towards the front axle, shedding that mass sharpens initial pedal response and extends the performance window under repeated hard stops. The two-piece floating construction lets the rotor expand without distorting, and braided lines keep the pedal firm. The Street, Sport and Racing compounds cover a broad temperature operating range, so the same kit handles daily commuting miles as capably as a morning at a circuit: Street is the quiet, low-dust default, Sport adds bite and heat range for fast road, and Racing is the dedicated track compound. The finish reads clearly on the CLA 4’s relatively open-spoke wheel designs, where the caliper is visible from the outside.

About the Hollow Front Big Brake Kit

Where a conventional disc-and-pad swap works within the stock caliper envelope, this XYZ Racing kit steps up to a hollow-vane disc, machining material from within each rotor to reduce mass without sacrificing structural rigidity, paired with a hollow-bodied caliper as standard. The lighter rotating assembly cuts inertia at the front axle, reduces heat build-up under repeated heavy braking, and gives a firmer, more progressive pedal feel compared to heavier solid or conventionally vented alternatives. Three compounds are available at the point of order: Street for quiet, low-dust everyday use, Sport for drivers mixing fast B-road miles with occasional track exposure, and Racing for those running the CLA 4 in competitive or regular circuit environments. Discs come drilled or slotted at the same price, and an optional Hollow Racing caliper upgrade for serious track work drops the dust cover, is rated to 1000C and carries a two-year warranty.

Caliper finish is confirmed when you order. Five painted colours are included at no extra cost: Red, Yellow, Gold, Black and Anodized Black. A Custom Color in any Pantone is £150, with premium polished-forged finishes in Titanium, Polished Gold and Polished Silver, plus candy finishes in Teal, Blue, Red and Orange. Two-tone centre bells in five anodized colours, or titanium, are selectable at checkout.

Fitment for the Mercedes Benz CLA 4 (2013-2019)

This front big brake kit is built for the Mercedes Benz CLA 4 in C117 body, covering the 2013 model year through to 2019. The specification applies to the 4MATIC variants of the first-generation CLA range. Confirm your front caliper specification before finalising your compound and colour choice when you order.

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 286–380mm (front). 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.
