BMW 1 Series ABS pump fault causing brake binding.

1 Series ABS brake binding fault

This ABS pump for BMW 1 Series (F20, F21) is a common failure that causes brake binding, sticking the brake caliper on when the brake pedal is depressed (even after releasing the brake pedal). Commonly rear brake binding will occur, but this can also happen on the front brakes. Most often affecting the 116 and 114 models, this fault extends to the entire 2011-2019 BMW 1 Series range.


You will also find that the brakes are automatically applied when the windscreen wipers are active and has been known to slow the vehicle drastically without the driver depressing the brake pedal.


This 1 Series ABS fault will not illuminate the ABS warning light or log any faults within the ABS module, so there is no warning before or during the malfunction.


With this fault affecting the 2010-2015 1 Series range most garages will seek to resolve this brake lock-up issue by purchasing a replacement ABS pump from the manufacturer. However, this is very expensive, will incur a programming fee, and due to the issue not being resolved at the factory all replacements are predisposed to fail in the future (usually after the short one-year manufacturer warranty).


We have a better solution to replacement: we can rebuild your original 1 Series ABS pump and module at a fraction of the cost of buying new. Not only this but we retain all original programming, work-out the original design flaw and provide a full unlimited mile Lifetime Warranty all within 2-3 working days.


You can rest assured that the rebuilt 1 Series ABS pump will no longer cause the brakes to bind/lock up.

How to diagnose:



Test and rebuild:

We test every unit beyond the operating parameters of the vehicle so we know that once a unit is rebuilt it will outlast the vehicle. We only use higher rated than standard components within our rebuilds. Testing of the BMW ABS unit is performed before and after the rebuild to ensure that the ABS meets or exceeds the OEM specifications.



The original programming information is retained for each BMW 1 Series ABS during testing and rebuild, meaning the unit is plug and play after a brake system bleed.



Our work defect rate is lower than 0.49% on all of our rebuilds and we are extremely proud of our Lifetime Warranty standards encompassing testing, workmanship, components and ESD safety. This is why main dealerships and specialists across the globe use our rebuild services.
