Why is my emergency brake not working on my Chevy Silverado?

What happens is the emergency brake, if not properly adjusted, wears a groove into the drum and prohibits the rotor from pulling off — you basically need to finesse it off and if that doesn’t work — pound it off.

Why do I get 0.2 volts on my brakes?

If the 0.2 volts that you are getting is when the brakes are not being applied then that is the signal that the brake controller sends back to the brake magnets to detect if a trailer is connected or not.

How can I tell if my brake rotor is resurfaced?

Every rotor has a “minimum spec” for thickness, usually stamped on the rotor near the hub where the lug nuts are.

How does ABS work on a Ford F250?

Your F250’s ABS system uses a system of sensors to determine wheel speed when braking. If one of the wheels is starting to lock up, it’ll apply the maximum amount of brake to that wheel in order to keep it from sliding. Wheels that are turning will slow a vehicle faster than a locked wheel.
