Brakes Lock Up After Installing Reverse Lockout Solenoid Valve # T4748800
Updated 03/20/2013 | Published 03/18/2013
Question:
Do you have to bleed your trailer brakes after re-installing this part. Also, my brakes appear to be locking up after I come to a complete stop and then start out again. Can this be due to a faulty solonoid part # T4748800? Note: I just replaced calipers, pads and rotors so I know those parts are not the problem. I think I narrowed it down to parts within the acuator.

I would recommend bleeding your brakes after installing a new Solenoid Valve, # T4748800. The main brake line must be disconnected from the actuator to install this item and anytime the brake lines are disconnected, there is a chance for air or some type of debris to enter the brake lines.
The electric lockout solenoid should not cause your brakes to lock up after you come to a complete stop. The solenoid has two wires, one should be connected to the reverse light circuit coming from the tow vehicle and the other wire should be grounded. Make sure you have the solenoid valve connected directly to the master cylinder and not to the orifice connector.
If you continue to have issues after bleeding the brakes and checking the connection of the solenoid valve, it may be possible that the shock in the actuator is going bad. Shock failure may also noticeable when you are bleeding the brakes.
