Brakes (A5)Question 59 of 120
The metering valve in a combination valve is used to:
a.Increase rear brake pressure
b.Warn of ABS faults
c.Bleed the master cylinder
d.Delay front disc application so rear drums engage together
Explanation
The metering valve holds off front disc pressure briefly so the rear drum shoes overcome their return springs and apply at nearly the same time, balancing braking. The proportioning section limits rear pressure to prevent lockup. Together these balance front-to-rear braking.
