Brakes - Careful, You Might Get What You Asked For

[wdk450]

Bill, I don't care what brand of pump you have, there should not be a 3-4 sec delay. Your controller is not talking nice to you pump. Parked, with the trailer hooked up. While standing by the pump, have someone step on the brakes. You should hear the pump start within 1 sec.
You can private message me and I will help you through this. Need to know the pump brand & serial# Both Carlisle and Dexter have had some recalls.

Titanguy: I was by the trailer mid-October when the welder's crew bled my brakes as one of the final steps of my big frame/suspension repair. The pump started immediately every time that the brake pedal was depressed. What the other poster was saying, and I think I am observing, is that the hydraulic pressure from the actuator takes 3 seconds to reach full pressure (1200 psi) when applying the brakes.

3 Sec. to reach full pressure on a Carlisle actuator is exactly what testing shows. But you should only "feel" the 1 sec. lag to get to activation of 250 psi. I have never used a Carlisle actuator and was not aware you could actually feel that much of a lag. Sounds like normal operation for the Carlisle Actuator.

The pump does not run at all in standby mode. Having the pump wired directly to the house battery provides a split sec. better response but not measureable.

So to be clear - wired directly to the house battery means that the pump is wired directly, not the controls and the pump is not spinning at a residual flow all the time. But, when the controls activates the pump, the pump is being powered directly from the house battery, correct?

For my own reasons I could see the benefit of that.
But, since there is no measurable reasoning for doing this - why do it?

The Titan EHB will work on all newer 2010+ Ford & GM trucks without the “black box”. Over the past 7+ years all pumps have had periodic issues with talking nicely to OEM integrated controllers. Most fixes are as easy as having the dealer update the brake controller electronics. No known issues exist with TV using aftermarket controllers. 98% of all integrated controllers work fine but when you are in the 2% it can be easily fixed.

And I for one would want to know that it will specifically work with the 2011+ Ford TBC, without issue. Keeping in mind that the Ford system does more then just apply brakes in normal stopping.

The Brakerite EHB is what is used on 95% of RV Trailer applications where there are 5 wires that are wired into the 7 way.

I saw on the web that it was only 5 wires. So if 5 wires wired into the 7 way - where is the wired directly to the house battery come into play?

What do you mean by reverse lock out?

OK, 1 question answered, the rest?

But, when the controls activates the pump, the pump is being powered directly from the house battery, correct? No the voltage from TBC fires the pump. The wiring to the house battery allows the brakes to operate when not hooked up to the TV.

For my own reasons I could see the benefit of that.

In 2011 Ford changed the TBC in mid year and update the TBC electronics in earlier units. So with the update the Brakerite should work without adding the "black box".

Wiring Diagram:
Blue wire to brake controller
White wire to ground
Black wire to hot
Brown wire to breakaway switch
These are typically wired in the junction box where the 7 way is wired into the trailer.

Violet wire to house battery

The benefit from wiring the actuator to the house (trailer) battery is so that if the trailer breaks away from the tow vehicle, the emergency lanyard switch will activate the brakes by turning on the actuator (powered by the trailer battery). This is required by law. If the actuator was powered by the truck battery, the brakes would not actuate upon disconnect from the tow vehicle.

I think we are discussing two different things Bill.
If I understand it correctly, the titan pump motor is wired directly to the battery for B12+, not the controls.

Benefit that I can see is that the motor has no power loss as compared to being powered by the vehicle through the 7-way.
