The easiest way to tell if the brakes are working on the trailer would be engage the manual override and have a friend sit outside the vehicle and watch the wheels on the trailer. If they begin to drag when you let off the brake pedal (slowly) on…

We do have tire chains that fit your size 17.5-24 tractor tires, though it is a different part number than the one you mentioned. I verified with the manufacturer for you that the correct chains for your 17.5-24 tractor tires are the following: -…

If the brake controller appears to working properly and the brakes of your electric over hydraulic setup are still not applying that would lead me to believe that the problem is on the actuator itself. Does the actuator cycle on to build pressure…

Thank you for all of the info you listed. Since you have a Dexter 3,500 lb trailer axle the correct bearing kit you need is the part #BK2-100 that you referenced which comes with the correct bearings, races, and seals. For grease I would recommend…

Bearings will be pretty tight on the spindle when they are installed. They should not be so tight that you have to really pound on them to fit but they can require a little bit of effort to get them to slide onto the spindle. When installed there…

You will naturally see some voltage drop from the brake controller all the way back to your trailer brakes, but what you're describing sounds like a bad ground somewhere. What you need to do is check the grounds related to the trailer brakes and…

On most breakaway kits such as the Hopkins Brake Master part #HM20001, you will not need to cut or splice any of the wires to move the trailer with a dead battery. If your power supply is not active, then the only effect is that the breakaway system…

I am not entirely sure what process you took so I'll give you some other things to try, or maybe a different way to test the Prodigy P3 #90195. First, sever the blue wire a couple inches from the back of your controller. Then use a circuit tester…

You are correct, you should only be getting output when the brake is applied, or the override switch is activated. It sounds like the controller might be bad, but to make sure, you should probably bench test it before tossing it. Use a circuit…

The is most likely related to the fact that there are two ways a 6-way will typically get wired and the only difference is that the 12 volt accessory circuit and the brake output circuit are switched. I attached a picture that shows a diagram for a…

It is a simple switch, so brand compatibility should be a non-issue. When the pin is pulled, two pins are allowed to contact and complete the circuit to engage the brakes. Any switch should work fine. I pulled the Hopkins Switch, part #HM20010, to…

If the drums look like they are in good shape you don't have to turn them when replacing the assemblies. Take a look at the inside of the drum and if you don't see any grooving or obvious signs of wear they don't have to be replaced.…
