Excessive Pedal Travel Inspection

1) 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 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 or brake fluid
leakage.
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".
