How to Repair Antilock Brakes

Antilock brakes help prevent your motor vehicle's brakes from locking up. Lockup may occur when you push too hard and fast on the brakes -- especially in less-than-ideal road conditions such as icy or slick roads. An antilock brake system seldom requires maintenance. However, routine checks of your general braking system will help keep your antilock brakes working fine. Although major repairs might require professional help, you can perform some brake maintenance at home.

Instructions

1

Attach a computer code reader to your car's computer plug, generally located near the dashboard, when the "ABS" light goes on. (See your vehicle's owner's manual for the exact location of the plug.)

2

Seek specific actions depending on the code. If the code indicates that your antilock braking system (ABS) has a mechanical part issue, you may need professional help. Other codes may indicate a circuitry error -- generally the cause of the ABS light coming on.

3

Park your vehicle on level ground, put it in park and raise it with a jack.

4

Go underneath your car, and locate the brake line -- generally near your brake pedal. (See your vehicle's owner's manual for the exact location.)

5

Check for leaks in the brake line. Put the canister underneath the brake line to see whether brake fluid is dripping into the canister. If the brake line is broken, you may need to seek professional help to replace the brake line.

6

Bleed your brake line: Disconnect it -- usually by just unscrewing the line from the hydraulic unit above it -- and let all the brake fluid drain out into a large canister or plate.

7

Reattach the brake fluid lines.

8

Open your hood, and locate the brake fluid holder -- generally near the front of the driver-side area under the hood.

9

Add brake fluid. Clean and new brake fluid allows your antilock brakes to work with a healthier braking system.
