• ABS is a technology which allows the driver to steer the vehicle while breaking heavily thereby saving life and providing better control of vehicle.
• When brakes are applied a hydraulic system is pressurized which causes the brake pads to squeeze against the discs and cause braking action.
• If the ABS Control Unit (B) detects locking of a wheel (due to low traction surface such as ice) through its wheel speed sensor (A), it signals the Hydraulic Unit (C) to release the brake pressure slightly.
• This lowers the pressure in brake pipe (D) causing the brake caliper to loosen the grip on brake disc of the locking wheel.
• If this rectifies the locked wheel condition, pressure is again built up to the optimum braking force by Hydraulic unit C.
