Excessive Pedal Travel Inspection
Excessive Pedal Travel Inspection1. Start engine.
2. Depress brake pedal a few times.
3. With brake pedal depressed with approximately 300 N (30 kg, 66 lbs) load, measure brake pedal to wall (dash panel silencer) clearance "a". If clearance "a" 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 "a" 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.
^ Remove brake drums for adjuster inspection. If defective, correct or replace.
Clearance "a" between brake pedal and dash panel silencer over 110 mm (4.33 inch)
