Fits Audi Q5 QUATTRO 8R (TYPE1) (2008-2017)

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.

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 — Audi Q5 QUATTRO 8R (TYPE1) (2008-2017) — 380 mm
380 mm

The first-generation Q5 8R carries its mass high and forward over a quattro driveline, and on a long downhill or a loaded motorway haul the rear axle quietly does more work than most owners credit it for. This XYZ Racing Hollow Rear Brake Kit gives that axle the thermal headroom a 1,800kg-plus SUV needs, replacing the standard rear setup with a larger two-piece floating disc and a forged caliper that resists the heat soak the factory rears struggle with once they get hot.

Specified for the rear of the Audi Q5 Quattro 8R, this big brake kit is about stability and stamina rather than headline stopping numbers. It steadies the back of the car under heavy braking, takes load off the front axle, and holds its bite when a soft, fading factory pedal would otherwise have you lifting early.

What this big brake kit does for your 2008-2017 Audi Q5 Quattro 8R

On the road you feel it most in the consistency: the pedal stays firm through repeated stops where the original rears would go long and woolly. The hollow-vane disc design trims rotational and unsprung mass at each rear corner, which sharpens how the Q5 settles over bumps and into a stop. Pad compound is your call, with Street for everyday driving, Sport for harder fast-road use and the odd track day, and Racing for sustained track or heavily loaded work. Braided lines hold the pedal firm as the fluid heats. Behind the wheel the result is a brake balance you can lean on with confidence, plus the visual lift of a proper forged caliper sitting behind the rear spokes.

About the Hollow Rear Brake Kit

The Hollow Rear Brake Kit pairs a larger two-piece floating disc with a forged caliper to manage heat better than a sliding factory unit. The caliper is hollow-bodied as standard, lightening the assembly while keeping the swept area needed to shed energy on a heavy SUV and helping the brakes recover between hard applications. Three pad compounds, Street, Sport and Racing, let you match the kit to how the car is actually used, from school runs to track days. Calipers come in your choice of Red, Yellow, Gold, Black or Anodized Black at no extra cost, with a custom Pantone shade available if you want an exact match. It is a rear-axle upgrade designed to complement a front kit and rebalance braking on a platform that was never light to begin with. Discs can be drilled or slotted at the same price, and the centre bell upgrades to two-tone anodized in five colours or titanium when you order.

Fitment for the Audi Q5 Quattro 8R (2008-2017)

This kit is specified for the rear axle of the first-generation Audi Q5 Quattro 8R (Type 1), covering the 2008 to 2017 model years. It is a rear-only application intended to work alongside the standard or upgraded front brakes on the 8R chassis.

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.
