Description
A known issue on various Vauxhall models is a failure within the ABS pump hydraulic unit, resulting in no brake fluid delivery to the front left brake caliper. This internal fault causes brake imbalance and can seriously affect braking performance and safety.
Common symptoms include:
-
Little or no braking force at the front left wheel
-
Vehicle pulling to one side under braking
-
Spongy or uneven brake pedal feel
-
No visible leaks or faults in brake lines or caliper
-
ABS warning light may or may not be present
This problem is usually caused by an internal valve failure inside the ABS hydraulic unit, not a mechanical issue with the caliper or brake lines.
