ATE 24.9145-0001.2 ABS pump

Description

VW ABS pump, or Anti-Lock Braking System pump, is a critical component that helps you maintain control during hard braking maneuvers, especially on slippery roads. Here’s how it works in your VW:

• Function: During hard braking, particularly on surfaces with low traction, a wheel can lock up and skid. This loss of traction makes it difficult to steer and can significantly increase stopping distances. The VW ABS pump works to prevent this by rapidly regulating hydraulic pressure in the braking system.

• The Process:

  1. Wheel speed sensors on each VW wheel constantly monitor wheel speed.
  2. If a sensor detects a wheel about to lock (slowing down significantly faster than the others), the ABS control module tells the pump to take action.
  3. The VW ABS pump quickly builds up pressure in the brake line going to the locking wheel.
  4. However, the pump doesn’t simply clamp down completely. It rapidly pulses the pressure, essentially applying and releasing pressure very quickly.
  5. This prevents the wheel from locking entirely and allows it to maintain some level of rotation, which is crucial for maintaining steering control.

• The Benefit: By preventing wheel lockup, the VW ABS pump helps you steer and maneuver the car even during hard braking on slippery surfaces. This can significantly improve stopping distances and avoid potential accidents.
