Brake Hose/Line: Description and Operation

Brake pipes





The brake pipes have an external diameter of approximately 4.75 mm (3/8 inch). If the braking system is fitted with TRACS, the brake pipe between the master cylinder primary circuit and the hydraulic unit has a diameter of 6.35 mm (1/4 inch). The volume of brake fluid in the pipe is therefore greater to ensure that the hydraulic pump gets enough brake fluid under TRACS control. The brake pipes and brake pipe routing to and from the master cylinder and hydraulic unit differs from LH to RH cars.
