Don't know if this is a common problem or not, but I have an issue with my brakes. When the ABS light is on the brakes are working ok (most of the time), but when it is off the brakes don't work properly, there is alot of grinding like the ABS is coming on and it's difficult to get the car to slow down without stamping on the brake. Don't know if I've explained myself properly but any advice would be gratefully received. Have been told it is either a sensor or a solenoid, but I have no idea.
