INFO ON HYDRAULIC TRAILER BRAKES


THE SINGLE-SERVO / DUO-SERVO DIFFERENCE:

1. SINGLE-SERVO: Single plunger coming from the wheel cylinder, most commonly used with Surge Brake applications.
2. DUO-SERVO: Two plungers coming from the wheel cylinder, stops vehicle in both forward and reverse motion.

 

REASONS WHY TRAILER BRAKE HARDWARE SHOULD BE REPLACED:

A. Worn, weak return springs will cause the brake linings to drag against the drum and cause premature brake failure.

B. Hold down springs will lose their tension and allow the brake shoes to wobble or ride up against the face of the brake drum, causing premature lining failure.

C. A frozen adjusting screw will not allow shoes to be adjusted properly.

D. Rubber dust plugs will crack with age and allow dirt to contaminate linings.

E. A stretched self-adjusting cable or worn lever prevents the self-adjusting lever from properly aligning the shoes.
