My breaks from time to time act possesed! I‘ll go to apply the brake pedal and I‘ll feel this vibrating resistence with a loud humming sound that sounds like an electric razor. Any ideas? Its a little scary because when this happens it wont allow me to brake? The only thing that sometimes work is to pump the brakes.
this is the same problem with our 200 dodge grad carvan. it is because the pump is not working at the rate it needs to so you need to pump your brakes to make them work. jiffy lube should be able to fix that.
You have a problem with your anti-lock braking system. Most likely, one of the four wheel speed sensors are bad, but sometimes there is a problem with another ABS component.
The problem you seem to be describing is condition known as unwanted abs activation.Newer vehicles with abs (anti-lock brake system) experience this problem when the brake is applied and your on an uneven road surface and a wheel is momentarily locked-up causing the brake computer to start pumping the brakes for you which is why you get the humming and vibration from the abs pump activating.Another common cause is a bad abs sensor sending a false signal to the computer.You should probably have someone check it out because brake problems are not something to be ignored
