INSPECTION OF BRAKE DRAG FORCE

Brake drag force inspection

1
Swing cylinder body upward.
2
Make sure that wheel bearing is adjusted properly. Refer to section FA.
3
Measure rotating force (F₁).
SBR456A
4
Install caliper with pads to original position.
5
Depress brake pedal for 5 seconds.
6
Release brake pedal and rotate disc rotor 10 revolutions.
7
Measure rotating force (F₂).
SBR457A
8
Calculate brake drag force by subtracting F₁ from F₂. If it is not within specification, check main pins and retainer boots in caliper.
