(i) Connect the connector to the stop light switch.
(j) Push in the brake pedal 5 - 15 mm (0.20 - 0.59 in.), turn
the stop light switch to lock the nut in the position where
the stop light goes off.
(k) After installation, push in the brake pedal 5 - 15 mm (0.20
- 0.59 in.), check that stop light lights up.
(l) After adjusting the pedal height, check the pedal freeplay.
(m) Install the thrust stopper, steering column assembly, col-
umn upper and lower covers, combination switch, steer-
ing wheel, steering wheel lower No. 2 and No. 3 covers,
and steering wheel pad (See page SR-14 or SR-29).
(n) Install the No. 2 heater to register duct, LH lower panel,

3. CHECK PEDAL FREEPLAY
(a) Stop the engine and depress the brake pedal more than
40 times until there is no more pressure 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.

NOTICE:
The pad retainer clip and clip can be used again provided
that they have sufficient rebound, no deformation, cracks
or wear, and have had all rust, dirt and foreign particles
cleaned off.
6. CHECK DISC THICKNESS AND DISC RUNOUT
(See page BR-21)

(b) Press in the piston with a hammer handle or an equiva-
lent.
HINT:
Always change the pads on one wheel at a time as there
is a possibility of opposite piston fling out.
If the piston is difficult to push in, loosen the bleeder plug
and push in the piston while letting some brake fluid es-
cape.
(c) Install the 2 pad retainers to each caliper piston.
