Frequently Asked Questions

What is an ABS outlet valve?

The outlet valve releases brake fluid pressure from the wheel brake circuit during ABS operation.

What happens if the outlet valve is stuck closed?

ABS cannot release brake pressure from the affected wheel, causing brake drag.

Is this related to the brake caliper?

No, the outlet valve is inside the ABS hydraulic unit, not at the brake caliper.
