What determines maximum legal stroke of a brake chamber push rod?
The brake chamber pushrod regulation stroke limits were established to ensure there is sufficient pushrod travel to apply full force to the foundation brake under all operating conditions. The limits are based on the size of the brake chamber and whether the chamber is a standard or long stroke design.
When brake chamber pushrod stroke exceeds the adjustment limit?
Inspection of brake adjustment at each wheel should be performed with air pressure between 621 and 690 kPa (90 and 100 psi ), the engine shut off and service brakes fully applied and spring brakes must be released.
