So, as I have said many times ! then we feel privileged to be able to service and repair such a diverse and varied number of car makes and models. Including cars from the BMW range.

This particular day as to be no different ! consequently, cars across the whole spectrum were booked in for repairs and services. Not forgetting MOT tests of course. One of the days jobs was a BMW that was suffering from its ABS (anti lock braking system) causing problems. So, the ABS system works by monitoring all the four wheel speeds . When the brakes are applied the system looks to see if any of the wheel are rotating at a lower speed than any of the other wheels.

This would then indicate that a wheel could be about to lock up. Alas, if there was of the wheels going at a higher speed than the other three then the brake would receive extra pressure to reduce the slip. So, the problem with this car was that the ABS was kicking in at low speed. not all the time but it annoyed the customer.

We placed the car on a ramp and endevoured to find the fault. Removing the wheels we were able to access the brake and inspect the drive shafts. So, on examination Ryan discovered that the drive shafts had corroded. Thus causing the target rings to swell and go out of shape. Consequently, the target rings had also damaged the ABS sensors.

We notified the BMW owner, who gave us permission to go ahead and repair his car. This is a good practice that I think most modern Autocentres now carry out. Gone are the days when the customer was presented with a massive repair bill. In my opinion this is best practice and both the garage and the customer know where they stand.

To repair the car ABS problems, we fitted new drive shafts and associated sensors. Of course we were confident that this would solve the problem ! and so it duly did.

This article is about your anti-lock braking system. Thus, ABS fitted onto your car is an additional safety feature. Hence, this is now found on many modern cars. Your cars ABS system. For this reason, is designed to help prevent your wheels from locking. Especially, during heavy braking situations, such as cornering on a wet or snowy road. Thus, your ABS will  prevent your car from skidding or Aquaplaning. Your ABS system is made up of the ABS module, and has sensors fitted on each of your wheels. As a result, these sensors detect your wheel speed.hence, this will send a message to the ABS module. This reacts by rapidly pumping the brakes when detected. Especially when the car is skidding and has lost the traction on a wet or icy road.

If your car is not fitted with an ABS system, then a lost of traction due to loss of traction. This could be caused by skidding, or aquaplaning on wet roads.  When you have to apply your brakes, then without ABS you could lose control of the car. As a result, your ABS system on your vehicle will give you plenty of warning signs when there is any problems with ABS system.

I think it is important for the driver to be aware of the warning signs. By knowing about the problems and correcting them, then you are more likely to be able to address the problem, should a problem occur. As I have said previously, ABS works by detecting individual wheel-lock and momentarily releasing the brakes on that particular wheel. Hence, by cutting out the amount of brake fluid. Which is supplied to the wheel via the master cylinder.Therefore to allow the wheel to regain traction and then carry on driving on in safety.
