Brake Proportioning/Combination Valve: Description and Operation
Proportioning Valve With ABS And Non-ABS TLEV
Proportioning Valve
Two in-line proportioning valves are used in the ITT Teves Mark 20 Antilock Brake System and on all Non-Antilock Brake applications. One
proportioning valve is located in each chassis brake tube at the rear flex hose of each rear wheel brake. The proportioning valves function the same as in
a standard brake system. The proportioning valve can be identified by the bar code label and stamp on the proportioning valve. Be sure replacement
proportioning valve have the same stamp as the proportioning valve being replaced. The proportioning valves are not serviceable, but are a replaceable
component.
On light pedal applications, equal brake pressure will be transmitted to the front and rear brakes. On heavier pedal applications the pressure transmitted
to the rear will be lower than the front brakes. This will prevent premature rear wheel skid. If hydraulic pressure is lost in one half of the diagonally split
system, the operation of the proportioning valve in the remaining half is not effected.
