Normally Closed - This solenoid valve is installed into a T-fitting from the master cylinder. NOTE: A “three port” valve is also available to eliminate the T-fitting. A return line from the valve, must be installed to return brake fluid into the master cylinder. Advantages ♦ Eliminates the Disadvantages with “Normally Open” Valves. Disadvantages ♦ Needs additional fittings, extra brake line, and requires drilling and tapping an access hole in the master cylinder for the return line.

Troubleshooting * For trailers with surge brake actuators Can Not Back Up Surge Braked Trailer Probable Cause Corrective Action 12 v. solenoid valve is inoperative. 1. Check tow vehicle back-up light circuit. Check 12 v. solenoid. (Should be able to hear a “click” when 12 v. DC is applied to lead wire.) 2. Check connection to tow vehicle back-up light circuit. 3. Check trailer ground connection (do not depend on hitch ball connection to provide ground).

Preventive Maintenance Check 1 - Visually brakes before each trip. (See pg. 3 #6) Check 2 - After each hook-up, check trailer brake operation before travel. Check 3 - Follow manufacturer’s recommendations for use and replacement of brake fluid. Check 4 - Wash brake assembly immediately after exposure to salt water or other corrosives. Check 5 - Occasionally check hub and assemblies to see they are within normal operating ranges (130º - 175º F).
