INSPECTION

M1351006300624

• Check the cylinder for wear, damage or rust.

• Check the piston surface for wear, damage or 

rust.

• Check the caliper body or sleeve for wear.

• Check the pad for damage or adhesion of grease, 

check the backing metal for damage.

PAD WEAR CHECK

WARNING

•

Always replace both brake pads on each 
wheel as a set (both front wheels or both 
rear wheels). Failure to do so will result in 
uneven braking, which may cause unrelia-
ble brake operation.

•

AC209106

If there is significant difference in the 
thickness of the pads on the left and right 
sides, check the sliding condition of the 
piston and slide pins.

1. Measure thickness at the thinnest and most worn 

area of the pad.

Standard value:

<LS, VR, VR-X>: 10.0 mm
<RALLIART Version-R>: 10.5 mm

Minimum limit:

<LS, VR, VR-X>: 2.0 mm
<RALLIART Version-R>: 1.5 mm

2. Replace the pad assembly if pad thickness is less 

than the limit value.
