You have a faulty or dirty ABS sensor, you can try to clean the ABS sensor with brake parts cleaner and inspect the wire leads. The ABS sensor are common to get dirt and the wire leads my be damaged due to corrosion or a break in the wire. The ABS sensor is located on the back side of the front wheel hub and the wires leads can be seen along the upper A-arms. Start with that and replace the sensor of all connections are good. Most auto parts store will have the ABS sensor on there shelf and can give you the step by step instructions like Auto Zone.

1.Why is my break light indicator on dashboard on even when break is not engaged.Note,my break is active and fluid level is ok. 2. Why is my ABS light on and refused go off from dashboard.


Because you have a problem in the ABS system . With the light being on there is a DTC -diagnostic trouble code stored in the ABS control module . EBCM - electronic brake control module . The red brake light also will come on with ABS problem . If you are unfamiliar with this I suggest you take your vehicle to a ASE certified repair facility that is .

ABS light stays on if car is started with parking brake engaged.


The ABS light illuminates when there is an "out of specification" condition. From your description, it sounds like your parking brake cable may require tightening, or there may be an issue where the rear brakes are not properly releasing when the parking brake is released. With car that is nearly 20 years old, it is not inconceivable that the rear brakes and parking brake assembly may require regular service.

A good first step would be to have error codes read out by a local mechanic or auto parts store. This may give you a better indication of the specific problem. In any case, ANY brake warning should be taken VERY SERIOUSLY and corrected IMMEDIATELY, as you may have a potentially dangerous potential of catastrophic brake failure. PLEASE GET THE ISSUE FIXED RIGHT AWAY!

ABS engages without braking


Check all wheel sensors for broken wires, loose connectors or position of sensors in their mounting brackets.

ABS engages without braking


You might check the rear Emergency brakes. The brake linings peel off the mounts and whirl around inside the E brake drum. The ABS sensors react to the garbage grinding up, blinding the sensors.

2005 Chevy impala brake pedal pulsation with brand new rotors installed


Is your ABS working properly? Under heavy braking the ABS should engage and 'pulse' the brakes on/off. It is normal to feel the brake petal flutter or pulse under your foot.

Under light braking there should be no pulsing as the ABS does not engage and you have changed the rotors and pads.

and the list keeps going on and on

ABS light on when cold, then goes off. The brakes grab and lock when stopped and will not release without major coaxing. It seems they engage at low cornering turns acting as if the vehicle is in 4wd....


Sounds like you have sticking caliper pistons, have you ever changed brake fluid? Replace calipers and flush brake fluid and clean ABS sensors with
ABS safe brake clean.
