Fits Audi A6 2.5 TDI QUATTRO AVANT (146) (1997-2004)

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 — Audi A6 2.5 TDI QUATTRO AVANT (146) (1997-2004) — 330 mm
330 mm

The C5 A6 Avant in 2.5 TDI Quattro form is a substantial piece of machinery: a diesel estate with all-wheel drive, a full boot, and the effortless high-speed cruising ability that regularly has drivers arriving at their braking points carrying far more momentum than the standard front hardware was specced to handle cleanly. On a long motorway run, loaded with family and luggage, or working down an alpine descent, the thermal demands on those front discs are a long way from what Audi’s engineers had in mind.

This XYZ Racing front brake kit addresses the C5 A6 2.5 TDI Quattro Avant directly at the front axle, where the quattro drivetrain’s braking bias concentrates the greatest thermal load under hard deceleration. It is a front-axle pair: left and right front calipers with matched two-piece floating discs, and three pad compounds covering everyday road use through to track and high-intensity work.

What this brake kit does for your 1997-2004 Audi A6 2.5 TDI QUATTRO AVANT (146)

The hollow-vane disc construction sheds heat more efficiently than a conventional vented disc of comparable diameter, because the internal geometry increases the effective surface-area-to-mass ratio. On a heavy diesel Avant with permanent quattro traction, sustained braking, repeated motorway stops, alpine descents with a full load, or a track day in a genuinely quick touring car, builds disc temperatures that cause conventional hardware to fade earlier than the pedal pressure suggests. The lighter two-piece discs also cut rotating and unsprung mass at the front, and braided lines hold the pedal firm where rubber hoses would swell. The three compounds let you match the pad to the use case: a daily driver on Street will live longer and bed in cleanly; Sport widens the heat range for fast-road work; Racing is the track compound for sustained high-temperature use. Calipers are hollow-bodied as standard, with a Hollow Racing upgrade for serious track use, rated to 1000C, no dust cover, two-year warranty.

About the Front Brake Kit

The kit takes its engineering rationale from the disc’s internal geometry: by structuring voids through the two-piece rotor body, XYZ Racing increases the rate at which heat transfers away from the swept surface under load. For a car carrying the mass of a fully laden C5 Avant Quattro, this is a concrete functional advantage rather than an aesthetic one. The kit is configured for the front axle, correct for the C5 platform, where the quattro system places the majority of deceleration force on the front discs under hard braking. Pad compound is selected when you order, with Street, Sport and Racing grades covering daily commuting through to sustained high-performance use. Discs come in drilled or slotted face at the same price, with optional two-tone centre bells in five anodized colours or titanium at checkout. Included caliper colours are Red, Yellow, Gold, Black and Anodized Black at no extra cost, with a Custom Color in any Pantone for £150 and premium polished-forged (Titanium, Polished Gold, Polished Silver) and candy finishes (Teal, Blue, Red, Orange) also available for colour-matched builds.

Fitment for the Audi A6 2.5 TDI QUATTRO AVANT (146) (1997-2004)

This front brake kit is confirmed for the C5-generation Audi A6 2.5 TDI Quattro Avant in 146 engine-variant specification, spanning the full model run from 1997 to 2004. It is a front-axle fitment. Verify your car’s existing front disc size before ordering, as late C5 A6 variants were optioned with differing factory brake packages depending on trim level.

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.
