Brake Master Cylinder: Description and Operation
Brake Master Cylinder - Description
DESCRIPTION
All master cylinders (2) are a two-outlet design and the brake tubes from these primary and secondary outlet ports lead directly to the Integrated Control
Unit (ICU) before going to each wheel brake.
All master cylinders mount to the power brake booster in the same manner.
The master cylinder body is an anodized aluminum casting. It has a machined bore to accept the master cylinder pistons and also has threaded ports with
seats for hydraulic brake tube connections.
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. A removable brake fluid level switch is mounted in the right side.
