Removing and Replacing Trailer Brake Shoes Review

Today we are going to show how to remove the break shoes on a typical electric break axle, this one in particular is a twelve inch drum. We are using that one because it is large and easy to see. This applies to virtually all electric brakes from this size on up and down to the smaller sizes. We will go over how it comes apart and the tools you will need to do it with.


Trailer Brake Controller Wiring Colors

Today we are going to cover a frequently asked question. It really turns up a lot. And actually it is easier than you think. Basically, if you have a pickup and you got a tow package with it and you got one of these wire harnesses that plug underneath the dash and plugs into your brake controller, you might have five or sometimes even more wires coming off of it. And you notice that your brake controller only uses four. We have got one over here, we will show you, that has just the four wires and what do you do with the extra wires? The short answer is do not worry about it, because the brake controller has all that it needs from these four wires.


Trailer Brake Controller Wire Testing

Today we are going to cover a few notes on testing an electronic brake controller. What we are going to cover here is going to apply to virtually all brake controllers. Basically, if you run into a problem where you think your brake controller is not working, well, it could be a the brake controller or it could be something in the truck itself, in the connector or c it actually could be problems in the trailer. What we are going to show you today is how to look for problems that will either rule out the brake controller or make sure that it is the brake controllers fault. Just like any electronic devices, they seem to have a limited lifespan some will work for years and some will not. But this way you can also verify that it is working good.


Trailer Brake Controller Comparison Review

Today we are going to talk about the two main kinds of brake controllers, the proportional and the time delay. The two we have here are the Journey HD and the Draw-Tite Activator II. These are what you call the time delay brake controllers. Basically what happens is that when you hit the brakes, they come on at a certain speed that you set on the brake controller. Like on this one here, we have a sync switch here that controls how fast it comes on and then this knob here controls how much power it takes to stop the trailer. Basically you hit your foot brake and it comes on at the rate you determine and at how much power you have set aside for it, and then it stays there until you completely let off the brake.


Diagnosing a Brake Controller Problem

Alright, today on this 2009 Ford F-150 we are going to diagnose a brake controller problem. Now we can use these steps on any brake controller that is on the market to verify if it is working or not. Now our brake controller is already telling us that it has an error message. It is flashing an Er on top. Usually it means an internal problem. We tested our trailer so we know it is good. So, it is not that. So first off we will make sure we have a constant 12 volt power supply. We will check the black wire first. OK, we are good there. Now we will try our red wire for our brake signal. OK, that is good there. Now we will try our blue wire and that will be our output. So we should have output on this wire whenever we hit the foot brake or the manual override. OK, we get nothing on the foot brake and nothing on the manual override. So definitely the error is internal and this brake controller does have to be replaced.


Trailer Brake Controller Installation Wiring Kit Review

Today we will show you part number ETBC7 brake controller installation kit. What this kit does is it fills in the blanks between your 4 pole connector and the brake controller. Basically on the instructions of your brake controller, it will show you a link between the foot brake and stop light switch, a battery, and then a line going out to the connector out back. This kit here fills in those missing pieces. We will cover each individual part. First we will start from the rear of the vehicle and work our way forward. This part here is 7 and 4 pole to 4 pole adapter. This will plug into your existing 4 pole that you have on your vehicle. It just plugs in like normal while this white wire gets grounded to the body of the vehicle. You will have a couple extra wires. The black wire will be ran to the battery. This blue wire here gets run to the blue wire on the brake controller.


Trailer Brake Controller Reverse Light Lead Installation

All right what we are going to do on this install is the reverse light lead to our electrical connector. For instance on a 5-pole you can use this on a boat trailer that has a reverse lock out for hydraulic brakes on it. Also you can use on a 7-pole application the trailer may have reverse lights on the back of it. Some RVs have a reverse light hook up on the back of it. I will show you the basic generic steps of how it is installed. 00:22

Brake Controller Questions and Answers

  • Troubleshooting a 2009 Integrated Brake Controller on a 2009 GMC Sierra that Quit Working
  • It sounds like you have some corrosion in your trailer connectors and that is why it seemed to work and then it stopped. Typically, when we see an intermittent electrical problem it is either corrosion or a weak ground or loose wire that causes the circuit to not work completely. My guess in your situation is that there is corrosion in the connector and that once you clean it the problem will go away. I attached an FAQ on trailer wiring for you to check out also.
