Brake Proportioning/Combination Valve: Description and Operation
Important: Do not wash proportioning valve in any cleaning solution. The internal components are prelubricated with a special grease.
The proportioning valves are located in the master cylinder and proportion the brake fluid to each caliper or wheel cylinder, after a predetermined
amount of pressure has been reached. This feature maintains a proper brake force "balance" during all braking maneuvers.
