Caliper render for this kit:
The W177 A35 4MATIC places greater thermal load on its front brakes than most hot hatches. The 4WD hardware adds mass forward, and the same all-wheel-drive traction that lets drivers carry more speed into braking zones also means those zones put sustained, repeatable heat through the factory discs and calipers. In road use the standard setup is adequate; on a track day, its limits arrive earlier than the rest of the car’s.
The XYZ Racing front brake kit for the Mercedes Benz A Class W177 A35 4WD (2019-2026) raises that thermal ceiling at the front axle. It is a matched pair of forged front calipers and two-piece floating discs, and three pad compounds, Street, Sport, and Racing, mean one system covers everything from a daily commute to a committed circuit session.
What this brake kit does for your 2019-2026 Mercedes Benz A Class W177 A35 4WD
The A35’s 4MATIC layout concentrates deceleration demand at the front, particularly under the late, confident braking entries that all-wheel-drive traction encourages. Upgrading to a big brake kit expands swept area and heat dissipation where the car needs it most, and the two-piece floating discs let the friction ring grow on its alloy bell without coning, giving a more consistent pedal under sustained load rather than the fade-then-recovery cycle the factory hardware produces when genuinely pushed. Street compound is the quiet, low-dust default that keeps road manners intact; Sport suits a car that does fast B-roads and occasional circuit sessions; Racing is for when lap time is the objective. Braided lines firm the pedal throughout, and painted caliper colours, Red, Yellow, Gold, Black, or Anodized Black at no cost, allow the installation to sit cleanly behind the A35’s wheel design. Discs are available drilled or slotted at the same price.
About the Hollow Front Brake Kit
The XYZ Racing series addresses a specific weakness in the thermal performance of factory brakes on modern performance hot hatches like the W177 A35 AMG. The caliper is a hollow-body forging as standard, which reduces rotational and unsprung mass without reducing swept surface area, an advantage on the W177’s front MacPherson strut setup where cutting wheel-end weight directly improves the strut’s ability to follow road imperfections under hard cornering load. For trailered circuit cars there is an optional Hollow Racing upgrade, with no dust cover, a 1000C rating, and a two-year warranty. Three pad compounds allow proper matching to actual usage: Street for the A35 that spends most of its life on the road, Sport for mixed road and circuit duty, Racing for the car that gets trailered to circuits. Caliper colour selection runs five no-cost finishes, Red, Yellow, Gold, Black, and Anodized Black, with a custom Pantone match for £150, premium polished-forged finishes in Titanium, Polished Gold, and Polished Silver, and candy finishes in Teal, Blue, Red, and Orange, spanning everything from understated to deliberately visible through the spokes. Centre bells can be specified two-tone or titanium.
Fitment for the Mercedes Benz A Class W177 A35 4WD (2019-2026)
This kit covers the Mercedes Benz A Class in W177 specification, specifically the A35 AMG in 4WD (4MATIC) configuration, across the 2019 to 2026 model years. Verify front wheel clearance before ordering: the W177 generation was offered with multiple alloy designs across standard and optional fitments, and clearance between the upgraded disc and spoke profile should be confirmed prior to installation.

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.
