Frequently Asked Questions
How does an ABS inlet valve work?
The inlet valve allows or blocks brake fluid from entering the wheel cylinder during ABS operation.
Can contaminated brake fluid damage ABS valves?
Yes, old or contaminated fluid can leave deposits that clog or stick ABS valves.
What happens if the valve is stuck open?
ABS cannot reduce braking pressure to that wheel, so it may lock up during hard braking.
