Brake Pedal Free Height Inspection

specification, check and adjust following item 2) and
6).
Brake pedal free height “a” from carpet
111 – 131 mm (4.4 – 5.1 in.)
2) Check measurement between booster mounting
surface and center of clevis pin hole. When booster
push rod clevis has been reinstalled, it is important
that the measurement is adjusted (refer to “Brake
Booster Inspection”).
3) Check brake light switch position. Adjust it if it is out
of specification.
4) Check pedal for dent.
5) Check brake booster for installation.
6) Check brake booster push rod for length.
Brake Pedal Play Inspection
S6RW0C4106002
Pedal play should be within the following specification. If

Excessive Pedal Travel Inspection
S6RW0C4106003
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”.
