What are some disadvantages of ABS?

Answer 1

There are only two disadvantages:

1. ABS will not stop you as fast on very loose surfaces like gravel or snow. On such surfaces with ABS on it will not allow a wedge of snow/gravel to build up in front of the tires that would nornally help you stop faster.

2. All ABS systems have a speed below which they have to stop working. It might be 3 or 4 MPH. This is because the basic function of ABS is to keep the wheels turning and if the wheels keep turning the car will never stop. It also has to do with the pulse rate from the wheels speed sensors. In either case once the car get to this speed the ABS turns off and the driver must adapt what he is doing. A classic case wouldbe trying to stop on an icy road, once below that lower speed limit you could slide quite far!
