ABS pump

To understand what an ABS pump is, it is important to understand the system to which the pump belongs.

The ABS pump is part of the anti-lock braking system (ABS), which are installed in most cars driving on the roads. The system usually consists of four components:

1) some sensors that monitor the car’s wheel speed and grip.

2) a valve system that determines how much the brakes tighten around the wheels

3) an ABS pump which supplies pressure to regulate the brakes

4) a control unit which analyzes the information from the sensors and tells the ABS pump how much pressure to apply or take off from the braking

Why is the ABS pump important?

The ABS pump is a central part of the safety system, which ensures that the braking time is as short as possible. In addition, the ABS co-works with ASR (anti-skid unit), so the car has a firm grip on the road.

In Denmark for instance, it is mandatory for new vehicles to be equipped with a so-called ESP system (electronic stability program system), which often includes an anti-lock braking system.

Thus, it is a great safety concern that the ABS of the vehicle is functioning well, and in this matter the ABS pump is as essential as the other parts of the system.

Symptoms of poor ABS pump

There are various symptoms that your ABS pump may need to be replaced.

Some cars have a dashboard safety lamp that tells you if something is wrong with the anti-lock braking system.

If your brake pedal does not respond normally or your brakes activate themselves while driving, it may also mean that you need to look for a new (or used) ABS pump.

Another indicator may be that the dashboard shows a speed of rotation of the wheels that does not match the reality.

Renovation or replacement

When it comes to hydraulic braking systems, it may sometimes be enough to renovate the parts of the system.

The valves that adjust the pressure in your anti-lock braking system can also be the cause of your problem if they are clogged.

If you get a mechanic to replace your ABS pump, he will know if another pump is really needed or whether the problem can be solved by a refurbishment.

A used ABS pump can last a long time

The life of ABS pumps is usually at least the same lifetime, as the lifetime of the car itself.

Consequently, you may find used ABS pumps cheap for sale in the market, which may still last decades.

If you choose to buy a used spare part, it is important that your dealer has a basic knowledge of ABS pump standards so that pump replacement does not compromise safety.

In other words, it is the ABS pump which, on order from the ABS sensors and the control unit, ensures that the braking remains under control.

When to replace an ABS pump?

Four indicators that your ABS pump should be replaced:

• If the ABS emergency light is activated on the dashboard
