BRAKE DISC CHECK
Refer to FRONT DISC BRAKE PAD of Section 5B for inspection
point and procedure.
BRAKE PAD CHECK
Inspect pad linings periodically according to maintenance schedule
whenever wheels are removed (for tire rotation or other reason).
Take a look through hole of caliper and check lining thickness of in-
side pad.
Thickness ªeº
Standard: 10.0 mm (0.39 in.)
Service Limit: 2.0 mm (0.08 in.)
If one of brake pad is worn to service limit, all linings must be re-
placed at the same time.
BRAKE SHOE CHECK
Inspection should be carried out on following points after brake ped-
al travel ªcº (pedal to asphalt sheet clearance) check as described
on previous page of this section, even when it is more than 115 mm
(4.53 in.).
Amount of brake shoe wear can be checked as follows.
1) Hoist vehicle.
2) Remove rubber plug from brake back plate.
3) Through hole of back plate, visually check for thickness of brake
shoe lining. If lining thickness ªfº is found less than below speci-
fied wear limit, replace with new brake shoes.
Thickness ªfº
Service Limit: 1.0 mm (0.04 in.)
