4. CHECK PEDAL RESERVE DISTANCE (W/O VSC)
Release the parking brake.
With the engine running, depress the pedal and measure the
pedal reserve distance, as shown in the illustration.
Pedal reserve distance from asphalt sheet at 490 N
(50 kgf, 110.2 lbf): More than 95 mm (3.74 in.)
If the reserve distance is incorrect, troubleshoot the brake sys-
tem.
5. CHECK PEDAL HEIGHT (w/ VSC)
Pedal height from dash panel:
Standard, access cab:
164.0 to 174.0 mm (6.46 to 6.85 in.)
Double cab:
151.1 to 165.1 mm (5.95 to 6.50 in.)
6. IF NECESSARY, ADJUST PEDAL HEIGHT (w/ VSC)
(a) Remove the scuff plate LH, cowl side trim LH, lower finish
panel and No. 2 heater to register duct (see page

(i) Push in the brake pedal 5 to 15 mm (0.20 to 0.59 in), turn
the stop light switch to lock the nut in the position where
the stop light goes off.
(j) After installation, push in the brake pedal 5 to 15 mm (0.20
to 0.59 in.) and check that the stop light lights up.
(k) After adjusting the pedal height, check the pedal free
play.

7. CHECK PEDAL FREE PLAY (w/ VSC)
(a) Stop the engine and depress the brake pedal several
times until there is no more vacuum left in the booster.
(b) Push in the pedal by hand until the second point of resis-
tance begins to be felt, then measure the distance as
shown in the illustration.
Pedal free play: 1 to 6 mm (0.04 to 0.24 in.)
If incorrect, check the stop light switch clearance. If the clear-
ance is OK, then troubleshoot the brake system.
