Brand

Choose the car before the badge. A brand may offer several calipers, disc sizes and pad choices for one model, while another brand may not list that car at all.

Use the categories below to see the live ranges. Then send us the make, model, year, engine, current brakes and wheel details. Garreth or Cameron can compare the kits that are actually made for that application.

Brake buying check: Brand reputation cannot answer wheel clearance or final kit specification. Compare the exact part numbers available for your car. Check disc diameter and thickness, caliper profile, included pads and hoses, replacement friction-ring availability and the maker’s instructions. Colour comes last. The product page is the specification. Do not carry piston count, disc construction or included hardware from one model to another.

Manufacturer application lists and fitting documents take priority over a general brand description.

Brake work is safety critical. Use a suitably experienced installer and the current vehicle and component instructions. Do not drive the car until the system has been checked, bled and tested as those documents require.
