Caliper render for this kit:

The E39 540’s M62 V8 carries real mass over the front axle, which leaves the rear brakes with a specific job: keeping a heavy executive saloon square and settled while the fronts do the hard stopping. This XYZ Racing Hollow Rear Brake Kit for the Bmw 5 Series E 39 540 (1995-2003) is built for exactly that, a rear setup that stays consistent when you are hauling a 1.7-tonne V8 down from motorway speed more than once in quick succession.
Most surviving 540s are still running tired factory rear discs and calipers that have done two decades of service. Swapping to a two-piece floating rotor and a fresh, stiffer caliper, a pair of left and right rear units, restores the firm, repeatable pedal these cars had when new, and gives you a rear axle that resists the heat soak that flat-spots an old setup on a long descent or a brisk B-road.
What this brake kit does for your 1995-2003 Bmw 5 Series E 39 540
The two-piece floating disc design strips rotating and unsprung mass from the back of the car, which sharpens how quickly the rear responds and takes load off the trailing arms. You feel it as a brake pedal that holds the same bite from cold through to a hot, worked rear axle, and as a 540 that stays composed rather than nervous when you brake deep into a corner. Pad compound choice sets the character: Street for refined, low-dust road manners, Sport for harder fast-road use with occasional track work, and Racing for repeated heavy stops where rear stability matters most. Caliper finishes run from the included painted colours of Red, Yellow, Gold, Black and Anodized Black through to a Custom Color in any Pantone, so the look behind the wheel matches the rest of the build.
About the Hollow Rear Brake Kit
The Hollow Rear Brake Kit pairs a lightweight two-piece floating disc with a purpose-matched rear caliper and your chosen pad compound, supplied as a pair of left and right rear units. The disc design lowers mass and opens up airflow paths to shed heat faster than a solid equivalent, which is what keeps a rear setup honest under repeat braking. The caliper body is hollow as standard, with a Hollow Racing upgrade for serious track use, no dust cover, rated to 1000C and backed by a two-year warranty. Three pad compounds, Street, Sport and Racing, let you tune rear bite to how the car is used, from daily duties to track days. The included painted caliper finishes are Red, Yellow, Gold, Black and Anodized Black at no cost, with a Custom Color in any Pantone available, and discs come drilled or slotted at the same price with centre-bell upgrades selectable at checkout. It is a bolt-on rear upgrade aimed at owners who want their E39 540 to stop with the authority the chassis was always capable of.

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.
