Place a drain pan under the wheel to catch any dripping brake fluid before proceeding. Remove the bolt that connects the brake line to the caliper. Remove the bolts, rubber boots and sliders holding the caliper in place. Drain any remaining brake fluid from the caliper.

Compress the new caliper completely using the caliper tool. Install the caliper, and attach the brake line to the new assembly.
Fill the brake fluid reservoir with new fluid. Have a helper press and hold the brake pedal while you open the bleeder valve. Close the valve, and ask the helper to release the brake. Continue the process until no bubbles appear in the fluid from the brake lines.
Put the wheel back on the car, and tighten the lug nuts. Lower the jack, and torque the lug nuts to the manufacturer's specification.
During a hard stop, if the brakes remain engaged with hard steady pressure for too long, the brake pads can overheat and cause the moving parts of the braking system to lock in position. Brake lock up is a particular danger on wet and slippery roads. Once the braking system locks up, much of the vehicle's control and stopping ability is compromised.Full Answer >
