Fits Nissan SENTRA B18 (2020-2026)

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 — Nissan SENTRA B18 (2020-2026) — 380 mm
380 mm

On a front-driven car like the Sentra B18, the rear axle never does the heavy lifting under braking. Weight pitches forward, the front discs take the brunt, and the factory rear setup is sized accordingly, adequate for the commute the car was built for, marginal once you start asking more of it. That is precisely why the rear is worth getting right. Brake balance, not outright rear clamping force, is what keeps a 2020-2026 Sentra composed when you trail the brakes into a tight autocross hairpin or a fast-road corner.

This XYZ Racing rear big brake kit for the Nissan Sentra B18 swaps the modest factory rear arrangement for a larger two-piece floating disc and a hollow-body caliper, supplied as a matched pair of left and right rear corners, with a pad compound chosen to match how you actually use the car. It is about repeatable, predictable retardation at the back axle rather than a headline stopping figure.

What this brake kit does for your 2020-2026 Nissan Sentra B18

The bigger rotor gives you more thermal mass at the rear, so the back brakes shrug off the heat that builds up during repeated stops, the situation where a stock comfort-biased Sentra rear can start to feel vague. A hollow-body caliper clamps more evenly than a sliding factory unit, which firms up pedal feel and tightens how the rear responds as you modulate pressure mid-corner, and the two-piece floating disc expands evenly under heat instead of coning. The three pad compounds let you set the car up for its job: Street for daily duty, Sport for spirited road use with occasional track, and Racing when the B18 sees regular track or autocross sessions. The disc comes drilled or slotted at the same price, so the look behind the wheel is yours to set as well.

About the Rear Big Brake Kit

A rear big brake kit is a bolt-on package built around a larger-diameter two-piece floating disc and a hollow-body caliper that replaces the smaller, often sliding, original equipment. The increased rotor size raises heat capacity and resistance to fade, the floating construction keeps the rotor flat as it heats, and the rigid caliper body flexes less under load than a single-piston floating design, translating more of your input into clamping force. Discs come drilled or slotted at the same price, with a two-tone centre bell in five anodized colours or titanium selectable at checkout. The kit ships with a choice of three pad compounds, Street, Sport and Racing, covering everything from quiet street manners to a high-friction track material, so the same hardware suits a daily Sentra or a weekend autocross car. Included caliper finishes at no extra cost are Red, Yellow, Gold, Black and Anodized Black; a Custom Color in any Pantone is £150, with premium polished-forged finishes in Titanium, Polished Gold and Polished Silver and candy options in Teal, Blue, Red and Orange. A Hollow Racing caliper is available for hard use, with no dust cover, a 1000C rating and a two-year warranty. As a rear-axle kit, its role is to restore brake balance front-to-rear, which is where a tuned FWD chassis like the Sentra B18 gains its real benefit.

Fitment for the Nissan Sentra B18 (2020-2026)

This kit is the rear-position application for the B18-generation Nissan Sentra, covering the 2020 to 2026 model years. It is designed around the B18 chassis specifically, so it matches the rear hub and mounting points of that platform. Confirm your model year falls within the 2020-2026 span, then set your pad compound, disc style and caliper colour in the buy options above.

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.
