Why are my ABS brakes not working properly?
On ABS, speed sensors are at the top of the list of failures. As far as the ABS problems are concerned, the first is speed sensors with metallic particles sticking to the sensor nose. This may cause system default, or make it constantly go into anti-lock mode called ‘false modulation.’
What to do when your rear brake is stuck?
The next step is to remove the wheel with the jammed brake (see wheel change if unsure of wheel removal) 4. With a front wheel chocked and in gear or park remove hand brake, using a soft hammer hit the brake drum between the wheel fixings, the shock should release the drum and it should now turn freely. 5.
What causes rear wheel to lock up when braking?

How does the ABS work when the wheel stops rotating?
ABS sensors tell a computer (called a controller) when a wheel stops rotating while the car is in motion, which indicates that the brakes have locked up at that particular wheel. The controller then directs a hydraulic valve to release some brake fluid pressure to the wheel in order to let it rotate again.

Why is my abs not working on my Harley Davidson?
The moisture will eventually contaminate the internals of the ABS modulator. When this occurs, the front or rear brake lever becomes rock hard and actual brake function is nonexistent. There are countless vehicles on the road, other than Harley Davidson, that utilize ABS systems and Dot 4 brake fluid.
What causes an unresponsive brake pedal in a car?
Unresponsive Brake Pedal In some cars, braking is directly linked with the ABS Control Module. This means the entire braking function is activated after going through the ABS module. If this is so and the module fails, your entire braking system can become unresponsive.
How does the ABS system work on a car?
The ABS system is made up of the ABS module, and ABS sensors at each wheel. The sensors detect wheel speed, and will send a message to the ABS module to rapidly pump the brakes when it is detected that the vehicle is skidding or has lost traction.

Sometimes the ABS light will come on because of a short or problem in the car’s computer that has little or nothing to do with the brake system at all.
What happens when an ABS wheel sensor fails?
Loss of Anti-lock Brakes When an ABS wheel sensor fails, it causes the anti-lock brakes to be inoperable. Anytime a fault is noticed, the system triggers an alert and the ABS warning light comes on. From here, the vehicle’s electronic control module stops receiving valuable data from the sensor.
