BR-6 < BASIC INSPECTION > FRONT DISC BRAKE BASIC INSPECTION FRONT DISC BRAKE BRAKE PAD INFOID:0000000009883526 PAD WEAR Check pad thickness from the inspection holes on cylinder body. Check using a scale if necessary. DISC ROTOR INFOID:0000000009883527 VISUAL Check surface of disc rotor for uneven wear, cracks, and serious damage. Replace as necessary. RUNOUT 1. Attach disc rotor to wheel hub using wheel nuts (at two or more positions). 2. Inspect runout using a dial gauge placed at 10 mm (0.39 in) inside the disc edge. NOTE: Before measuring, make sure that wheel bearing axial end play is within the specification. Refer to . 3. When runout exceeds limit value, displace mounting positions of disc rotor by one hole. And then find a position of the minimum value for runout. 4. If runout is outside the specified value after performing the above operation, turn disc rotor using Tool. THICKNESS Check thickness of the disc rotor using a micrometer. Replace disc rotor if thickness is less than the wear limit. Standard thickness : Refer to . Repair limit thickness : Refer to . WFIA0522E Runout limit . (with it attached to the vehicle) Tool number : 38-PFM90.5 ( — ) BRA0580D Standard thickness : Refer to . Repair limit thickness : Refer to . Maximum uneven wear : Refer to .
