An ABS light (anti-lock braking system) that turns on doesn’t necessarily mean you need an ABS brake repair. The light is generally seen on the dashboard on your control console next to the speedometer and gauges, and it could be caused by issues other than problems with the anti-lock brakes. The light staying on can be caused by something as simple as the emergency brake or more complicated things like a loss of brake fluid and pressure or bad hydraulic valves.
INSPECT THE EMERGENCY BRAKE
Sometimes the emergency brake may not go down far enough and keep the light on, even though the brakes are really not applied.
The emergency brake does not work on the same system as the main brake line, but if the E-brake is in working order, it can still be applied in a situation where the main lines fail. It can also be applied as a preventative measure in areas with steep driving area. However, this light can get triggered on if the handle is not shut off completely.
Check your E-brake to be sure that it is in the proper right position. Adjust a few times and see if the light goes off.
LOSS OF HYDRAULIC PRESSURE
During your ABS brake light check, you will want to check the levels in your brake reservoir to see if it has lost a large amount of brake fluid. The warning light can come on from low levels of the fluid in the brake system.
Alternatively, if the levels are topped off, it could be that you are losing pressure on one side of the car, which can be dangerous. Losing this pressure can make the brakes to fail while on the road, and the danger increases as the car increases in speed, as the system will not be as effective in stopping the car
INSPECT YOUR HYDRAULIC CIRCUITS
Your car has two hydraulic circuits, and you will want to check those to well. The dual hydraulic system acts as a fail backup in case the main line fails, so there is still the possibility that the second set of brakes will kick in and allow the vehicle to stop. These are manufacture into a check valve system that allows one to turn on as the other shuts off.
If you notice broken parts in the hydraulic circuits, you can change them out, but if the ABS light stays on, you may have a more serious issue in the actual.
ABS LIGHT IS STILL ON
The main thing to know in this situation is that if the light continues on after you have checked through all the systems, you will want to get it checked professionally to forestall serious injury or death when operating the car. An ABS brake repair will be required, and mechanic shops will be able to more thoroughly check the entire system for leaks or cracks in the brake fluid reservoir and the brake lines, which could be the source of your pressure loss.
