Brake Pedal Assy: Testing and Inspection

EXCESSIVE PEDAL TRAVEL CHECK
1. Start engine.
2. Depress brake pedal a few times.
3. With brake pedal depressed with approximately 30 kg (66 lbs.) load, measure brake pedal to wall clearance "c" should be: Over 90 mm (3.54 inches).
4. If clearance "c" is less than specification, the most possible cause is either rear brake shoes are worn out beyond limit or air is in lines. Should clearance "c" remain less than specification even after replacement of brake shoes and bleeding of system, other possible but infrequent cause is malfunction of rear brake shoe adjusters or booster push rod length out of adjustment.
^ Bleed brake system. Service and Repair
^ Remove brake drums for adjuster inspection. If defective, correct or replace.





PEDAL PLAY INSPECTION
Pedal play should be within specification "f": 1-8 mm (0.04-0.31 inch). If out of specification, check stop light switch for proper installation position and adjust if necessary. Also check pedal shaft bolt and master cylinder pin installation for looseness and replace if defective.
