Diagnose and Fix Brake Locking Issues in Ford Fiesta, C-Max, Transit & More: A Guide to Faulty ATE MK100 ABS Units

Brakes locking on, binding or sticking is a common problem for the Ford Fiesta, B-Max, C-Max and Transit. It’s often caused by a faulty ATE MK100 ABS unit. This article aims to shed more light into how to effectively diagnose and fix this frustrating issue.  


Describing the problem

Brakes locking, sticking or binding refers to a situation where the brake pads remain in contact with the brake disc even after the pedal has been released. This issue poses a legitimate safety risk and can lead to accelerated wear of brake components.

The root cause is often related to the ATE MK100 ABS unit that requires in depth diagnostic investigation to repair. There are multiple issues that cause these symptoms. 

Issues with the flow and pressure of your brake fluid

A faulty master cylinder can also lead to locking, sticking or binding. It could prevent the pressure from being released quickly enough. In addition to the master cylinder, you should inspect the hydraulic system for blocked or restricted lines, defective vales or damaged seals.

The master cylinder feeds fluid to the ABS unit which directs it through the hydraulic control unit and to each corner of the vehicle. Failures in any part of the braking system could result in poor drivability symptoms.
