The rear brakes have a self-adjusting mechanism that does not require adjustment for proper drum to shoe clearance when brake shoe has been replaced or brake drum has been removed for some other service.
Adjustment is automatically accomplished by depressing brake pedal 3-5 times after all parts are installed. Then check brake drum for dragging and brake system for proper performance.
Brake pedal height is determined by brake pedal booster pushrod length and brake light switch adjustment. Brake pedal height is normal if the brake pedal is as high as the clutch pedal. If brake pedal height is not normal, check brake pedal booster pushrod length and brake light switch adjustments.
