BRAKE PEDAL

INSPECTION AFTER REMOVAL

Check rivets in upper part of brake pedal are not deformed.

Check that joint length “L” of sub-bracket and sliding plate is 5.5
mm (0.217 in) or more.

Check brake pedal for bend, damage, and cracks on the welded
parts.

Replace brake pedal assembly if detected.

Check clevis pin and plastic stopper for damage and deforma-
tion. Replace clevis pin if there are.
INSTALLATION
Install in reverse order of the removal.

When installing brake pedal, tighten nuts and bolt according to
the order shown in the figure.

Check brake pedal for smooth operation. There should be no
binding or sticking when applying or releasing brake pedal.

Adjust brake pedal height after installing brake pedal assembly
to vehicle. Refer to BR-6, "
Inspection and Adjustment" .

INSPECTION AFTER REMOVAL
Output Rod Length Inspection
1. Using a handy vacuum pump, apply a vacuum of −66.7 kPa (−
500 mmHg, −19.69 inHg) to brake booster.
2. Check output rod length.
INSTALLATION
1. Loosen lock nut to adjust input rod length so that the length “B”
(shown in the figure) satisfies the specified value.
2. Temporarily tighten lock nut after adjusting the length “B” to the
specified value, and then install brake booster on dash panel.
CAUTION:
Always install gasket between brake booster and dash-
board panel.
3. Install brake booster and brake pedal assembly nuts and bolt,
and then tighten to the specified torque. Refer to BR-7,
"Removal and Installation" .
4. Connect brake pedal with clevis of input rod.
5. Install brake master cylinder. Refer to BR-14, "
Removal and Installation" .
6. Install vacuum hose. Refer to BR-24, "
VACUUM LINES" .
7. Adjust brake pedal free height and the play of brake pedal. Refer to BR-6, "
Inspection and Adjustment" .
8. Tighten input rod lock nut to the specified torque. Refer to BR-22, "
COMPONENTS" .
9. Refill with new brake fluid and bleed air. Refer to BR-11, "
Hydraulic Circuit" . Standard dimension when applying vacuum of −66.7
