Master Cylinder, Brake: Description
All master cylinders are a two-outlet design and the brake tubes from these primary (2) and secondary (4) outlet ports lead directly to the Integrated Control Unit (ICU) before going to each wheel brake.
The master cylinder has the brake fluid reservoir mounted on top of it which gravity feeds brake fluid to the master cylinder when it is required. On manual transmission model vehicles the brake fluid reservoir also feeds the clutch hydraulic circuit. The reservoir is made of see-through plastic and it houses the brake fluid level switch (3).
