🔧 Peugeot brakes binding with no clear fault?
🛠 ATE MK100 ABS pump may be the true cause—not the caliper
🚚 We offer fast ABS pump repair with UK-wide collection and a lifetime warranty

If you’re struggling with Peugeot brakes binding—especially after already replacing the caliper or hose—you might be facing a fault inside the ATE MK100 ABS pump. This unit is commonly fitted to Peugeot and Citroen vehicles and is known to cause brake drag when one of its internal valves fails to release.
At ECU Fix, we specialise in repairing this exact fault. Our service restores the ABS unit’s internal hydraulic function, without requiring coding or replacement. Every repair is backed by a lifetime warranty.
🔧 Peugeot Brakes Binding – Why It’s Often the ATE MK100 ABS Pump
In affected vehicles, a wheel may remain partially or fully engaged after braking—even with your foot off the pedal. This is caused by a sticking valve inside the ABS pump, not a fault in the brake caliper or lines.
Here’s what happens:
- The ATE MK100 contains solenoid valves that regulate fluid pressure to each caliper
- When a valve fails to reopen, fluid pressure stays locked at that wheel
- The brake remains applied, often without any ABS warning light
- The result: persistent Peugeot brakes binding, usually at the rear axle
This issue is difficult to diagnose and often leads to unnecessary part replacements—until the ABS pump is properly tested.
⚠️ Peugeot Brakes Binding Symptoms from ABS Valve Failure
You may notice:
- One wheel overheating or dragging after driving
- Vehicle pulling to one side during or after braking
- Brake only releasing when you manually bleed the caliper
- Caliper, pads, and flexi hoses already replaced with no improvement
- No fault codes or ABS warning lights present
If you’ve experienced these issues, you’re likely dealing with a faulty ATE MK100 ABS pump—not hardware.

FAQs
Why do my brakes keep binding?
If your brakes keep binding, even after replacing pads, hoses, or calipers, the issue may lie in the ABS pump. On vehicles like Peugeot and Citroen, the ATE MK100 ABS unit can suffer internal valve faults that trap brake pressure at one or more wheels, causing persistent brake drag.
Can ABS cause brake binding?
Yes. A faulty ABS pump, particularly the ATE MK100 unit used in many Peugeot and Citroen models, can cause brake binding. This happens when a valve inside the pump fails to release pressure after braking, keeping the caliper engaged even when the pedal is released.
Is brake binding an MOT failure?
Yes, brake binding will result in an MOT failure. If one or more wheels are found to drag or resist free movement during brake testing, the vehicle is considered unsafe due to unbalanced or ineffective braking.
What can cause the brakes to lock up?
Brakes may lock up due to:
- A seized caliper or slide pin
- A blocked flexi hose
- Incorrectly fitted pads
- Or more commonly, an internal ABS pump fault—particularly if the lock-up affects one wheel and returns after parts have been changed
In many modern vehicles, a sticking valve inside the ABS modulator is a hidden cause often missed in early diagnosis.
