Full Answer

When brakes skid, they have less traction. They do not grip the road properly. Anti-lock braking systems allow drivers to steer while they are slowing down safely. There are several parts to the system. The speed sensor components tell the ABS how the wheels are acting. The valve for each brake controls the amount of pressure in the system. A pump replaces pressure that has been released by the valves. The computerized controller regulates the system. When the ABS is engaged, the activity of the valves causes the driver to notice a pulsing sensation in the brakes.

  • Q:

    What happens when your ABS light comes on?

    A:

    The ABS light comes on whenever there is a fault in the anti-lock braking system in a vehicle. The fault can be a low amount of fluid in the ABS reservoir to an electrical malfunction in the wheel speed sensor, control unit or the pump, but regular braking function is unaffected. Repair involves testing or replacing control unit and pump, the wheel speed sensors or power cycling the entire system.

  • Q:

    How do you troubleshoot problems with an ABS brake system?

    A:

    The first step to troubleshooting an anti-lock brake system is checking the fuse that manages the brakes. If the fuse is functional, check the harness of the ABS controller for signs of corrosion. Then check the wheel sensors. If those are in order, you might need a new ABS controller.
