• Trailer Brakes Dragging on Downhill Runs with a Demco Disc Brake Actuator
• The first thing you should check is the brake adjustment on the brakes themselves. If they are improperly adjusted, readjustment could solve the issue. We have a video detailing how to adjust trailer brakes, check out the 4 minute 30 second mark in the video attached below. You should also check the breakaway lever, to be sure it is not partially activated. The next thing to check is the coupler capacity and the gross weight of the trailer the coupler is mounted on. If the trailer weight

• Recommendation for Installation of a Brake Mounting Flange on a Trailer Spindle and Axle
• Welding a mounting flange, possible item # 4-35, is a very precise installation. The flanges need to be installed square and concentric to the hub and drum assembly and each other. If the flange is installed incorrectly rapid brake lining wear, improper braking, trailer dog legging, bearing failure, rapid tire wear and, worst of all, weakening of the axle can occur. Usually special jigs are used to install the flange. The jig will keep the flange square and concentric to the axle and spindle

• How To Reverse Without Trailer Brakes Locking When Using Demco Actuator Coupler, # DA9150-2HBC
• The Demco Actuator, # DA9150-2HBC, does not have a reverse lockout feature so you would need hydraulic free-baking drum brakes on the trailer in order to back up without actuating the brakes. I have included a link to all of the free-backing brakes for you to view.

• Can a Weld-On A-Frame Trailer Coupler be Bolted On Instead of Welded
• The A-frame couplers we carry, like # 12660-97SP, are weld-on applications and cannot be bolted on to a trailer frame. Any welding should be done by a qualified welder in a shop that works on trailers. The coupler you have reference accepts a 2-5/16 inch diameter ball. I have included a link to all of the A-frame coupler options for you to view.

• Coupler Lock Recommendation for use on a Coupler that has a 5 inch Wide Flange
• It looks like would need to get a latch coupler lock like a Master Lock Adjustable Trailer Coupler Lock - Stainless Steel, part # 2847DAT, for your Four Winns trailer that has a 5 inch wide flange. I attached a link to a review video of this coupler lock for you to check out. We do not have a surround coupler lock that will be wide enough to fit on a coupler that has a distance of 5 inches across.

• Installing Hydraulic Trailer Brakes on a Kristi Utility Trailer
• There are two ways to go. Drum brakes and Disc brakes. To determine which assemblies will fit on your spindles we will need to know the inner and outer bearing and seal part numbers. We will also need the Brake Mounting Flange bolt pattern on the spindles and the bolt pattern and size of the wheels that are on your trailer. For the hydraulic actuator we will need the size of the trailer tongue where the actuator will mount. If you will get back to me with your choices and the needed informati

• How To Check if Trailer Surge Brakes Are Working Properly On Tandem Axle Boat Trailer
• Checking the brakes can be done in two ways. The easiest way is to raise one side of the trailer and spin the wheels while someone applies the surge brakes at the coupler. The better way would be to remove each of the wheels and brake drums and activate the brakes while making sure the wheel cylinders and brake assemblies are functioning properly. After this the first thing I would do is bleed the brakes using the trailers surge coupler to force the fluid from the brake lines and make sure th

• Advice for Reomving Deteriorated Master Brake Clinder Cap on Hydraulic Brake Coupler
• The challenge here is to keep the remains of the cap in one piece long enough to remove it. I would suggest mixing up some 2 part epoxy and coating the cap with it. If you are careful to avoid getting the epoxy down into the threaded portion of the cap, once it cures you should be able to get the cap off. If you should get pieces of the cap into the master cylinder, most hydraulic couplers are set up so that the master cylinder is removable, you could remove it if needed and clean it out.
