Abstract: A brake assembly includes a guide spring for returning a parking brake actuator arm to a release position and which serves to guide an apply cable into engagement with the actuator arm during assembly. The guide spring is inhibited from deflecting during insertion of the cable by a retaining spring that spans across the opposing lower brake shoe ends at the adjuster link and which includes an extending tail positioned adjacent the guide spring.

Abstract: A dual brake circuit master cylinder with center compensation on the second circuit is provided. The master cylinder has a second piston mounted within a housing bore sealably separating a second reservoir passage from the second brake circuit passage when the pressure within the bore exposed to the second brake circuit passage exceeds the pressure within the bore exposed to the second reservoir passage. The second piston also has a compensating passage with an inclusive valve seat with an inserted compensating valve allowing fluid communication between the second reservoir and second brake circuit passages when the pressure in the second reservoir is greater than the pressure in the brake circuit. An auxiliary piston is provided to insure that the second compensating valve is retained to an open position when ever the second piston is in a retracted position and excessive pressure in the brake second circuit has acted to close the second compensating valve.
