Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Excessive Pedal Travel Inspection
- Start engine.
- Depress brake pedal a few times.
- With brake pedal depressed with approximately 300 N (30.6 kgf, 67.4 lbf) load, measure brake pedal to wall (dash panel silencer) clearance "a". If clearance is out of specification, possible causes are as follows. If clearance "a" is less than specification, the most possible cause is that air is in lines.
Should clearance "a" remain less than specification even after bleeding of system, other possible but infrequent cause is malfunction of booster push rod length out of adjustment.
- Bleed brake system. Refer to AIR BLEEDING OF BRAKE SYSTEM .
- Remove brake drums for adjuster inspection (rear drum brake model). (Refer to REAR BRAKE DRUM REMOVAL AND INSTALLATION
.) If defective, correct or replace.
Brake pedal to wall clearance "a"
When pedal is depressed at 300 N (30.6 kgf, 67.4 lbf): over 40 mm (1.57 in.)
