BRAKES - Front inspect / remove

Loosen the wheel lug nuts, raise the vehicle and support it securely on jack-stands. Remove the wheel.
Remove the brake caliper, pads and torque plate. It's NOT necessary to remove the brake hose. After removing the caliper, suspend it out of the way with a piece of wire.

Visually inspect the disc surface for scoring and other damage. Light scratches and shallow grooves are normal after use and may not always be detrimental to brake operation, but deep scoring - over 0.015 inch (0.38mm) - requires disc removal and refinishing by an automotive machine shop. Be sure to check both sides of the disc. If pulsating has been noticed during application of the brakes, suspect disc run-out.
To check disc run-out, place a dial indicator at a point about 1/2-inch from the outer edge of the disc. Set the indicator to zero and turn the disc. The difference between the highest and lowest indicator reading should not exceed the specified allowable run-out maximum. If it does, the disc should be refinished by a professional.
Note: Professionals recommend resurfacing of brake discs regardless of the dial indicator reading (to produce a smooth, flat surface that will eliminate brake pedal pulsations and other undesirable symptoms related to questionable discs). At the very least, if you elect not to have your discs resurfaced, de-glaze them with medium-grit emery cloth (use a swirling motion to ensure a non-directional finish).
It is absolutely critical that the disc not be machined to a thickness under the specified minimum allowable thickness. This thickness is stamped onto the inner diameter of the disc. The disc thickness can be checked with a micrometer.

Remove the cap from the brake fluid reservoir, siphon off about two thirds of the fluid into a container and discard the fluid. Brake fluid will damage paint, so be careful not to spill any.
Disconnect the brake line from the caliper by removing the inlet fitting bolt. Plug the end of the line to prevent excessive brake fluid loss.
Remove the caliper mounting bolts, or on some models, the lock pin. On models secured by a lock pin, swing the caliper up until it clears the disc and slide it off the upper pin. The brake pads can stay in the torque plate.
Installation is the opposite of removal.
