Locking or binding brakes refers to a situation where the brake pads remain in contact with the brake discs even after the brake pedal is released. This problem poses significant safety risks and can lead to accelerated wear of brake components. The root cause is often related to the ATE MK100 ABS system, which requires targeted troubleshooting and repair. There are several possible causes for this problem.

Defective ABS sensor

A malfunctioning wheel speed sensor can send inaccurate signals to the ABS module, resulting in incorrect brake activation. Always check the ABS sensors for damage, misalignment or loose connections. Use diagnostic equipment to monitor sensor data and ensure accurate readings.

Problems with brake fluid pressure cause an error in the ABS module

A malfunctioning brake master cylinder / uneven distribution of brake fluid pressure can also cause the brakes to lock, lock or bind. As a result, the pressure does not release quickly enough. So, in addition to the brake master cylinder, thoroughly examine the hydraulic system for clogged/restricted brake lines, faulty valves, or damaged seals. The ABS receives brake fluid through the brake lines which leads into the plugs in the hydraulic section. Once this is no longer the case, this can result in brake locking/binding problems. One of the main solutions for locking of brakes on Ford Fiesta, B-Max, C-Max and Transit models is to have the ATE MK100 ABS system remanufactured. Automotive technicians can rely on ACTRONICS for this service, which offers several benefits.
