Frequently Asked Questions
Can a faulty outlet valve damage the brakes?
A stuck-closed outlet valve causes brake drag, leading to premature pad and rotor wear.
Why does my rear brake drag after ABS activates?
The outlet valve may not properly release pressure after ABS deactivates, trapping pressure in the caliper.
Should I replace all ABS valves at once?
Since valves are usually part of the hydraulic unit, the entire unit is typically replaced.
