Brake Pedal Assy: Testing and Inspection
EXCESSIVE PEDAL TRAVEL CHECK1. Start engine.
2. Depress brake pedal a few times.
3. With brake pedal depressed with approximately 30 kg (66 lbs.) load, measure pedal to carpet clearance "c".
CAUTION: Make sure that carpet is attached to vehicle body tightly when taking measurement.
Clearance "c": over 100 mm (3.94 inch)
4. If clearance "c" is less than 100 mm (3.94 inch), 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 100 mm (3.94 inch) 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 for the vehicle with brake booster.
