Fits Toyota PREVIA TCR21W (4WD) (1990-1999)

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 — Toyota PREVIA TCR21W (4WD) (1990-1999) — 330 mm
330 mm

The Toyota Previa TCR21W carries close to two tonnes on a platform designed around interior space rather than stopping power, and its underfloor mid-mounted supercharged engine sits a large share of that mass low and central. The XYZ Racing Hollow Front Brake Kit answers the single biggest weakness of working this 4WD Previa hard: a standard front setup that was never specified to haul a fully laden van down repeatedly without the pedal going long.

This is a front-axle big brake kit, a matched pair of front calipers and discs, for owners who tow, load up, or simply drive a TCR21W with intent and have felt the factory discs soften on a sustained descent. It puts brake hardware on the front of the Previa that is sized to the weight the chassis actually has to arrest.

What this big brake kit does for your 1990-1999 Toyota Previa TCR21W (4WD)

After fitting, the first thing you feel is a firmer, higher pedal that stays consistent when the standard brakes would have started to fade. The larger front disc and multi-piston caliper give the heavy 4WD Previa more thermal capacity, so a long motorway descent or a loaded run no longer cooks the front end into a spongy pedal. Three pad compounds let you match the kit to how you use the van: Street is the quiet, low-dust road default, Sport adds bite and heat range for towing and fast-road duty, and Racing is the dedicated track compound for the most demanding repeat-stop work. The result is shorter, more confident stops from a vehicle that, in standard form, asks a lot of an undersized front brake.

About the Hollow Front Brake Kit

The Hollow Front Brake Kit is XYZ Racing’s front-axle upgrade for heavy platforms like the Previa. The two-piece floating disc trims rotating and unsprung mass while its vane structure moves heat out of the rotor faster than a solid factory disc manages, and the floating bell handles thermal expansion cleanly. The caliper is a fixed multi-piston unit, hollow-bodied as standard, that clamps the larger disc more evenly than the sliding single-piston original, which keeps pad wear flatter and pedal feel sharper. The kit is offered with three pad compounds, Street, Sport and Racing, so the friction level can be set to the duty cycle rather than left as a single compromise. Discs are available drilled or slotted at the same price. Painted caliper finishes are included at no cost in Red, Yellow, Gold, Black and Anodized Black, with a Custom Color in any Pantone at £150 and premium polished-forged Titanium, Polished Gold or Polished Silver, plus candy Teal, Blue, Red and Orange. Centre bells upgrade to two-tone anodizing in five colours or titanium, and the Hollow Racing caliper option removes the dust cover, is rated to 1000C and carries a two-year warranty for serious track use.

Fitment for the Toyota PREVIA TCR21W (4WD) (1990-1999)

This kit is built for the front axle of the Toyota Previa TCR21W in 4WD form, covering the 1990 to 1999 production span and supplied as a left-and-right pair. The TCR21W chassis code is the specific fitment here, so confirm your Previa carries that designation before ordering. Pad compound, disc style and caliper colour are all selected when you order.

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.
