9. Inspect the brake friction lining
(a). Inspect the brake friction lining for any damage, excessive wear or deformation. If necessary,
replace the brake friction lining.
(b). Inspect the depth from the rivet head to

Brake friction the friction lining surface and the
Brale shoe lining damage thickness of the friction lining;
replace it if they are beyond the limit
value.
Wear limit value of friction lining:

Vehicle type Limit

1051 series 4.6 ± 0.2 mm

1061 series 4.6 ± 0.2 mm
1089 series 4.6 ± 0.2 mm

Wear limit value of depth from
the friction lining surface to the
rivet head:

Vehicle type Limit

1051 series 7.7 mm

1061 series 9.2 mm

1089 series 9.7 mm

10. INSPECT THE BRAKE SHOE
RETRACTING SPRING
(a). Inspect the retracting spring for any
26 cracks or deformation (especially the
hooks on both ends). Inspect the free
length, load and load length of the
spring.
Spring load and load length:

Vehicle tyle Spring Load Load Length

1051 series 384 N 148 mm
1061 series 384 N 148 mm

1089 series 384 N 148 mm

11. Inspect the brake backing plate
(a). Inspect the brake backing plate for any cracks or deformation, if necessary, replace it.
