Yes, when you press your brake pedal for your air brakes on your truck it will tell your brake controller like the Hayes Air Actuated Trailer Brake Controller # HA100400C to activate the HydraStar Electric Over Hydraulic Actuator # HBA-10 on your trailer. You will need to confirm that your trailer brake controller is compatible with electric over hydraulic brakes like the Hayes unit is.
To test your actuator you can pull the emergency break away cable to ensure that the actuator activates... view full answer...
Disc brake actuators like # T4747200 do not have a check valve in them or a device to keep pressure in the system like drum brake actuators do. On a drum brake actuator there is a check valve inside the master cylinder that regulates the amount of pressure that goes back to the brakes. The wheel cylinders on hydraulic drum brakes will hold pressure as well.
If the master cylinder and wheel cylinders (if the trailer has drum brakes) are fine then you could have some air in the system or... view full answer...
If the pump is running but not building pressure it could be a mechanical or electrical issue. Make sure that all of the wiring is intact with no corrosion on the connections. The actuator should be grounded to both the ground on the trailer connector and to the negative battery terminal on the trailer.
You may also need to bleed the brakes. Check the manual of the actuator you have for the bleeding procedure. It could also be a problem with the breakaway system or the battery on the trailer.... view full answer...
To properly operate the actuator # K71-651, the brake controller you are using needs to be compatible with electric over hydraulic braking systems. We offer the Tekonsha Prodigy P2, part # 90885 that would work great for you.
If the brake controller is turned up to maximum gain, you should be getting 12 volts on the blue wire feeding the actuator (when the controller is activated). The black wire feeding the actuator should show a constant 12 volts. If you do not have a multimeter, we... view full answer...
It sounds like you have a factory brake controller in your new truck that doesn't like to work with electric over hydraulic actuators. This is a fairly common problem as most factory brake controllers in trucks either don't work all the time with an EOH actuator or they don't work some of the time.
Your best option would be a brake controller like the P2 part # 90885 that can easily be used with trailers that have EOH actuators.
Or you have a short on your brake output circuit to the... view full answer...
The factory brake controller on your 2018 Ford F-450 is designed to work on electric over hydraulic brake systems. One note I did find in your owners manual is brake output is diminished by the truck at speeds of 11mph or lower so this will explain why when you press the brake pedal you do not get the same output as when using the manual activation. The simplest way to test the actuator is by simply pulling the breakaway cable and verifying it does activate and continuously run. You will... view full answer...
The first thing I recommend checking is the output setting on the brake controller. If adjusting the power level does nothing to solve the problem, then we can work out way back. Check the vehicle and trailer side connectors for any dirt or corrosion because this can cause a short.
Next move on to the trailer and check the wiring for the actuator. The unit must be wired like in the diagram I have included. If there is a short in the breakaway wiring, the pin is pulled out from the switch,... view full answer...
There are a couple of possible issues that are occurring with the Dexter DX Series Electric Over Hydraulic Brake Actuator for Disc Brakes # K71-651 or Drum Brakes # K71-650 which are causing your brakes to smoke.
First, you will want to ensure you are wired properly, as per the accompanying diagram. If it is, you can troubleshoot it with a 12 volt battery. According to Dexter, you will want to first detach all wires from the actuator, and once you do this, connect the white wire to the... view full answer...
I spoke with my contact at Titan about the issue you are having with the Titan Zinc-Plated Brake Actuator w/ Electric Lockout - Disc - 2-5/16 inch Ball - 8,000 lbs, part # T4747220, on your trailer.
He informed me that there is no pressure adjustment on the trailer actuator, and that the breaking intensity is completely proportional to the braking intensity of the towing vehicle. He said most likely that the brake system needed to be bled again.
There is a way to test the brake system.... view full answer...
First thing I would do is test the wiring of the Dexter Electric Over Hydraulic Brake Actuator # K71-651. Connect the trailer to your tow vehicle so that the actuator pulsates like you said it was doing and then probe the blue wire with a circuit tester like part # 3808. If the tester shows pulsating voltage at the same time the actuator is pulsating then you know the problem is the brake controller.
I suspect that it's the brake controller since integrated brake controllers don't always... view full answer...
The brake actuators we offer are designed for the trailer weight and tongue weight capacities, and will work the same regardless of the surface you are on. If the reverse lockout is disengaging and locking up the brakes on your trailer, then you may have a bad solenoid, or a bad actuator.
If you have a Titan Model 6, Model 60, Aero 7500, or newer Model 10 or Model 20 actuator, and also Dico Models 10, 20 and 60 actuators, the replacement solenoid is part # T4748800. For 2000 and older... view full answer...
When bleeding the brakes on a surge actuator, such as the Dexter DX7.5L A-60 Brake Actuator w Electric Lockout # DX56FR, you want to start by making sure there is fresh fluid in the reservoir then press a screw driver against the rod in the access hole to pump the brakes. If you don't have an access hole, wrap the safety chains around a pole or board and push the top into the coupler to force the pumping action that way. I attached a detailed write-up page that explains this process, and... view full answer...
I completely understand, it's always nice to try to salvage what you have before purchasing again. I can explain the difference to you, and might have a possible solution for you.
Drum and disk brake actuators use different pressures for operation. Drum brake actuators typically produce 1000-psi pressure while disc brake actuators produce 1500 or 1600-psi pressure.
The higher pressure of a disc actuator could blow out the wheel cylinders of a drum brake assembly so you cannot use the... view full answer...
I spoke with my contact at Dexter and there is a way to troubleshoot your actuator. If you use a 12 volt battery and connect just the white wire from the actuator to the negative post and then connect the black wire to the positive side of the battery, you could possibly hear a click sound but the actuator should not turn on. If it does turn on and run, the unit is defective and needs to be replaced. This would be done without having the blue wire connected.
If you have disc brakes on... view full answer...
I called HydraStar who is a prominent manufacturer of electric over hydraulic brake actuators and they said the issue that you are having is caused by a compatibility error between the factory integrated brake controller and your electric over hydraulic brake actuator. Therefore, you will need to use an adapter. Please also make sure that you are in the electric over hydraulic mode if that is an option. In order to recommend the correct adapter I will need to know what electric over hydraulic... view full answer...
It sounds like there may be an issue with the wiring in the trailer to the hydraulic brake actuator. When you installed the Adapter Module # DX35FR you did receive the trailer connected message.
I have attached the instructions for the Adapter Module that shows several different wiring schematics for the popular hydraulic actuators. If yours is not listed let me know and I will help you find the correct wiring.
It sounds like there may be issue with the power wire that is going into... view full answer...
There are several possibilities that could be causing your brakes to not function properly. Is there a certain reason you believe the issue to be the master cylinder? Poor braking performance may not mean a faulty master cylinder.
The first thing you will want to check is the brake adjustment. It could be that the brakes need to be adjusted and so they are not functioning. Another option is to take the hub off to inspect the brake pad to see how much brake pad is left. This is a good... view full answer...
There are a few different issues that could cause your Titan EHB actuator to not build pressure. The first and easiest things to check is the ground connection and fluid level. A poor ground is the most common cause for electric-over-hydraulic actuators to fail. The actuator should be grounded to a 12 volt battery, not the trailer frame. The trailer frame is not a suitable ground location for this actuator.
If you adjust the ground connection and the unit will still not pressurize, you... view full answer...
It is possible for the actuator inside the Hydrastar Electric Over Hydraulic Actuator for Disc Brakes # HBA16 to go bad. The brake fluid should be checked with a tester to determine if moisture is mixing with the brake fluid. As moisture gets into the fluid it can cause corrosion to build up inside the actuator and brake lines. This corrosion can cause the actuator to freeze up or debris to get into the lines and clog the lines or the calipers. I recommend attempting to bleed the entire... view full answer...
I spoke to my contact at Demco and he told that the Demco Hydraulic Brake Actuator # DM62VR should not slam forward when you slow down. He said this brake actuator is inertia based, meaning as you start to apply the brakes it will begin to slowly activate your trailer's brakes. It should not be where the brake actuator slams forward as you say.
There are a couple of things he said that could be causing the problem. The first thing he said could be the issue are the bolts that hold the... view full answer...
