You need a jack, four jack stands, a tire wrench and brake fluid to repair an antilock brake system. To repair the system, first switch off the ignition, and pump the brakes about 30 times to depressurize the system. Raise the vehicle with a jack, and support it with support stands. Unbolt the tire with a tire wrench, remove the tire, and set it aside. Pry out the caliper.

Pry off the old pads, and install new pads. Examine the brake system, including the master cylinder, vacuum hoses and brake cylinder. Replace the parts if necessary.

Change the break fluid, and pump the brakes several times until no bubbles are produced. Replace the caliper. Secure the tire back in place with a tire wrench and bolts. Slightly raise the vehicle with a jack, remove the support stands, and lower the vehicle. Pump the brakes to build up pressure in the ABS, turn on the ignition key, and check the brake system warning lights.
