required, wipe valves clean using brake fluid. Do not use a solvent to clean the valves, as it could enter the small notches (vent) of valves and
cause damage to the internal seals of the valves.
3.
Inspect the front and rear proportioner valves to determine if either one or both of the valves need to be replaced. Refer to Figure 1. Use a
magnifying glass to identify the valves. Proportioner valves from three different sources were used interchangeably; therefore, both front and rear
valves will not require replacement in all cases.
4.
Replace all proportioner valves, as instructed in Part II of this procedure, that are of design shown in View A of Figure 1. If the valve
identification cannot be accurately determined, or there is a question on identification, valve(s) should be replaced.
Special care should be taken to ensure that specified torque valves are used when installing new proportioner valves.
5.
If valves are the design shown in View B or View C of Figure 1, no further action is required except to install a campaign identification label as
instructed in Part III of this procedure.
