BRAKE PAD CHECK

M1351017300048

CAUTION

If there is a significant difference in the thicknesses of the 
pads on the left and right sides, check moving parts (Refer 
to 

P.35A-21

).

1. Visually check the thickness of brake pad from the 

inspection hole of the caliper body.

Standard value:

9.85 mm (0.39 inch) <Front>
9.0 mm (0.35 inch) <Rear>

Limit: 2.0 mm (0.08 inch)

2. When the thickness is lower than the limit value, replace 

both brake pads (right and left) as a set (Refer to 

P.35A-18

).

CAUTION

• Take care not to contact the parts or tools to the caliper 

because the paint of caliper will be scratched. And if 
there is brake fluid on the caliper, wipe it off quickly.

• Whenever a pad must be replaced, replace both LH and 

RH wheel pads as a set to prevent the vehicle from pull-
ing to one side when braking.

1. While pressing the cross spring by hand, remove the pin 

from the brake caliper assembly.

2. Remove the cross spring from the brake caliper assembly.
