the brake disc again.
2. If the run-out cannot be corrected by changing the phase of the brake disc, replace the brake disc or turn the rotor with an on the car type brake
lathe ("MAD. DL-8700PF or equivalent).
Be sure to follow the exact brake lathe manufacturer instructions. Rotors turned on the vehicle will often have a lower run-out than a new brake
disc.
FRONT BRAKE DISC THICKNESS CHECK
1. Using a micrometer, measure disc thickness at eight positions, approximately 45° apart and 10 mm (0.39 inch) from the outer edge of the disc.
Brake disc thickness
Standard value: 24.4 mm (0.96 inch)
Limit: 22.4 mm (0.88 inch)
Thickness variation (at least 8 positions)
The difference between any thickness measurer meets should not be more than 0.005 mm (0.0006 inch).
2. If the disc is beyond the limits for thickness, remove it and install a new one. If thickness variation exceeds the specification, replace the brake disc
or turn rotor with an on the car type brake lathe ("MAD. DL-8700PF or equivalent).
Be sure to follow the exact brake lathe manufacturer instructions.
REASSEMBLY
1. Clean the components with isopropyl alcohol except for the pad and shim.
2. Install the piston seal.
3. After applying the specified brake fluid to the piston outer surface, install the piston into the cylinder.
4. Install the piston boot and boot ring.
