not machine a new brake disc.
7. For vehicles with a two- piece hub and brake disc assembly:
z Match-mark before disassembly.
z Remove the brake disc.
z Using a die grinder with a mild abrasive (Scotch Brite® type), remove any rust or
corrosion from the hub and brake disc mounting surfaces.
z Align the match- marks and reinstall the brake disc on the hub.
8. CAUTION: Do not use a bench lathe to machine brake discs.
NOTE: The depth of cut must be between 0.10 and 0.20 mm (0.004 and 0.008 inch). Lighter
cuts will cause heat and wear. Heavier cuts will cause poor brake disc surface finish.
Using on- vehicle brake lathe, machine the brake discs. Follow the manufacturer's instructions.
After machining, make sure the brake disc still meets the thickness specification.
9. Using a dial indicator, verify that the brake disc lateral runout is now within vehicle specification.
10. Remove any metal chips.
11. Remove the hub adapter.
12. Remove any remaining metal chips from the machining operation.
13. CAUTION: Do not carry out this step on rear drum- in-hat brake discs.
For vehicles with a two- piece hub and a non drum- in-hat brake disc assembly:
z Remove the brake disc from the hub.
z Remove any remaining metal chips from hub and brake disc mounting surfaces and from
the ABS sensor.
z Apply High Temperature Nickel Anti- Seize Lubricant F6AZ-9L494-AA to the mounting
surfaces.
z Using the match- marks, mount the brake disc on the hub.
14. Install the caliper and check brake operation.

primary and secondary piston.
z Brake master cylinder pistons apply hydraulic pressure to the two hydraulic circuits.
z Brake master cylinder will not be overhauled, a new master cylinder is installed only.
The brake master cylinder consists of:
zbrake master cylinder reservoir (2K478)
z brake master cylinder body
Brake Master Cylinder Reservoir
NOTE: Whenever the brake master cylinder reservoir is removed from the brake master cylinder, new
grommets must be installed.
The brake master cylinder reservoir :
zis mounted to the brake master cylinder.

Hydro-Boost
Removal WARNING: The power brake booster should not be carried by the accumulator, nor
should it ever be dropped on the accumulator. Check the snap ring on the accumulator for
correct seating before the power brake booster is used. The accumulator contains high-
pressure nitrogen gas and can be dangerous if mishandled.
WARNING: If the accumulator is to be disposed of, it must not be exposed to excessive
heat. Before discarding the accumulator, drill a 1.6- mm (1/16-inch) diameter hole in the end of
the accumulator can to relieve the gas pressure. Always wear safety glasses when performing
this operation.
1. With the engine off, depress the brake pedal (2455) several times to discharge the accumulator.
