EBC Apollo Big Brake Kit for Toyota GR Supra and BMW | BBK042

Give your Supra or BMW brakes that feel ready for the drive

The right brake upgrade makes a capable car even more satisfying to use. The EBC Apollo BBK042 pairs six-piston front calipers with a choice of 380 mm or 355 mm floating discs for the listed GR Supra and BMW applications. It is a substantial hardware upgrade for a firmer pedal and repeated braking heat, with the factory brake-package conditions kept clear below.

Kit reference: BBK042. Exact SKUs for every available configuration are listed below.

A choice of hardware with a clear purpose

The reinforced caliper body helps keep the response precise under pressure, while the floating disc ring can expand separately from its bell when it gets hot. Both versions use that approach; the larger disc is not an automatic fitment upgrade for every application or wheel. Match the version to your car, including the relevant M Sport or M Performance brake notes where listed.

Calipers made for the way you use your car

The road calipers are designed, manufactured and assembled in the UK from heat-treated, low-pressure cast aluminium. Their two-piece bodies use grade 12.9 bridge bolts, with hard-anodised aluminium pistons, stainless-steel bleed nipples and wear plates. The material and construction put substance behind the appearance of the upgrade.

External dust boots keep road dirt and debris away from the pistons, with high-temperature EPDM fluid seals behind them. A hard-anodised body gives corrosion protection beneath the high-temperature colour coating, while the single pad-retention bolt allows quick pad changes when servicing is due.

Choose your kit

Version 1 uses 380 mm discs; Version 2 uses 355 x 32 mm discs. Both have six-piston calipers. The application table separates the version-specific vehicle coverage and original brake conditions. Check your exact wheel template before choosing either size.

Black, Blue, Red and Yellow are the painted road-caliper choices, with external dust boots and aluminium pistons. Choose the finish you want to see behind your wheels without changing the kit specification for that version.

Race competition is a different hardware and pad specification: hard-anodised calipers, stainless-steel castellated pistons and RP-X race pads. It is intended for dedicated track and race use, rather than chosen as another paint colour.

Road-kit front pads: Version 2: Bluestuff.

Bluestuff combines cold bite for road use with capability for lighter track work. Dedicated racing asks something different of a pad; use the competition specification where that is the car's purpose.

What is included

With the painted road configurations you receive:

• Two Apollo front calipers in the selected road colour
• Two fully floating two-piece front discs to the selected kit specification
• Front brake pads (Version 2: Bluestuff)
• Stainless-steel braided brake lines
• Vehicle-specific mounting brackets and fitting hardware
• 1 litre of BF307+ Super DOT 4 brake fluid

The Race competition front brake assembly combines Apollo competition calipers, fully floating two-piece discs to the selected specification and RP-X race pads.

Vehicle fitment

Match your vehicle, engine, year and any brake-package notes in the table. Disc measurements in this fitment table describe the original brakes; the new kit dimensions are listed under Technical specifications and in the SKU table.

Application years can vary by engine and kit option; check the detailed rows for your vehicle.

Fitting and looking after your brakes

Have the kit fitted by a qualified brake specialist. The installation needs clean, sound mounting surfaces, the correct hardware and torques, proper bleeding, and clearance checks through steering and suspension movement. Dust-shield removal or modification can be part of fitting; keep any vehicle-specific instructions in the application table with the job.

The road kit is designed around the original master cylinder and rear brakes. If you have changed the master cylinder or rear brake arrangement separately, have your installer check compatibility and brake balance before ordering.

Follow the fitting instructions and the bedding procedure for the supplied pad compound before demanding full performance. When rear components are supplied, fit them as part of the intended brake upgrade. Inspect pad and disc condition regularly, especially during circuit use, and keep the hydraulic system in good condition.
