Brake Line

PERIODIC MAINTENANCE SERVICES

16.Brake Line

A: INSPECTION

1. BRAKE LINE

1) Check for scratches, swelling, corrosion, traces
of fluid leakage on the brake hoses or pipe joints.
2) Check the possibility of adjacent parts interfering
with brake pipes/hoses during driving, and loose
connections/clamps.
3) Check any trace of fluid leakage, scratches, etc.
on master cylinder, wheel cylinder and pressure
control valve.

NOTE:
• When the brake fluid level in the reservoir tank is
lower than specified limit, the brake warning light
on the combination meter will illuminate.
• Visually check the brake hose for damage. (Use
a mirror where it is difficult to see)

2. SERVICE BRAKE

1) Check the free play of brake pedal by pulling up
the pedal with a force of 10 N (1 kgf, 2 lb) or less.

Brake pedal free play (Pulling up direction of
pedal)

0.5 — 2.0 mm (0.02 — 0.08 in)

2) If the free play is out of specifications above, ad-
just the brake pedal as follows.

(1) Make sure the engine is off. (No vacuum is
applied to brake booster.)
(2) There should be play between brake boost-
er clevis and pin at brake pedal installing por-
tion. [Pulling up the brake pedal pad with a force
of 10 N (1 kgf, 2 lb) or less to a stroke of 0.5 to
2.0 mm (0.02 to 0.08 in).]
(3) If there is no free play between clevis pin
and clevis, turn brake switch adjusting nut until
the clearance between stopper and screw of
brake switch becomes 0.3 mm (0.012 in).
