HFM.Parts have re-developed the original BRZ/86 Brake Master Cylinder with a 25.4mm bore and increased the diameter to 27mm. This is the perfect application if you are increasing your braking performance by upgrading to multi-piston calipers, and it will help to give you a firmer brake pedal with less travel.
The dark colour of HFM.Parts Brake Masters come from their Geomet® coating. As well as providing some heat protection and environmental resistance, this coating is environmentally friendly as it contains no Chromium, the leftover solution is recycled and no chemicals are evaporated.
