XYZ Racing Hollow Front Brake Kit — Audi A4 B7 (2004-2008)

The B7 A4 sits modestly in the Audi range, but quattro variants in particular carry serious nose weight: the longitudinal engine well forward of the front axle, all-wheel-drive hardware distributed behind it, and a front-biased mass that loads the brakes hard on any committed approach. Factory stoppers cope with routine driving, but sustained pressure, a fast alpine descent or a morning at a track day, reveals their ceiling. Pedal feel muddies, modulation narrows, and confidence erodes at exactly the moment you need it most.

The XYZ Racing front brake kit for the Audi A4 B7 is a front-axle upgrade: a matched pair of left and right front calipers with two-piece floating discs, built around a choice of three pad compounds so the specification can match how the car is actually used rather than defaulting to a single compromise.

What this brake kit does for your 2004-2008 Audi A4 B7

The two-piece floating discs reduce rotating and unsprung weight at the axle most heavily loaded during braking on the B7’s front-biased platform. Less rotating mass means quicker thermal recovery between stops, a firmer pedal under repeated hard use, and more consistent bite across a range of speeds. The hollow-vane disc design moves more air through the rotor body to shed heat between applications, and braided lines hold the pedal firm where rubber hoses would swell. Three pad compounds let owners match friction to use: Street is the quiet, low-dust road default across the full B7 engine line-up, Sport suits spirited fast-road work in the torquier quattro turbo variants, and Racing is the track compound for circuit conditions where rotor temperatures would otherwise overwhelm a road pad’s fade resistance. 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 defining element is the two-piece floating front disc: a lighter rotor that reduces overall mass without cutting swept area, which directly addresses the heat-cycle behaviour behind progressive fade during repeated hard stops. Because the rotors shed heat faster between applications, pedal feel stays firmer across a sequence of braking events rather than softening incrementally. 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. The three pad compounds extend the kit’s range from routine commuting through to track days, with the Racing grade designed to hold its friction coefficient at the temperatures the B7’s front-biased geometry generates under circuit conditions.

Fitment for the Audi A4 B7 (2004-2008)

This front brake kit covers the Audi A4 B7 generation across the 2004 to 2008 model years, encompassing both saloon and Avant body styles in front-wheel-drive and quattro configurations. Verify your existing front caliper specification before ordering, as brake hardware can vary across the B7 engine and trim range.
