Recall on electric over hydraulic brakes

I recently purchased a 2004 25 feet limited with electric over hydraulic brakes which locked up on me shortly after purchase. The AS in Alachua FL. now to repair anyone experienced this? Joe

If this trailer has sat for a long time the pads may be sticking in the anchors or piston may be sticking in the calipers.

Is it all wheels?

not sure but the 2004 may have been a retrofit to e/h brakes. They may be Kodiak which are a sliding style caliper. These are subject to seizures. If this is the case you should pull off the wheels and lubricate the 'slide pins' with a silicone based grease. If they are factory originals they are probably Dexter brakes. These are a fixed caliper design with four brake pistons on each. with these the issue from sitting is rust developing on the piston sides and in the caliper bores from leaking piston seals. As requested above if all brakes locked up, you need to focus on the brake controller/pump assembly. Is it an Accubrake or a Dexter? In order to be of any great assistance we would need to know what brake components you are dealing with. Lots of info on the Forum. All the best.... Pete

Yes it sat for a year in a pasture but the hydraulic pump continuously runs and makes a groaning continuous sound until I pull the plug out of the brake box under the forward end of the camper.

Runs continuous, 7 way plug connected to tow vehicle or disconnected.

Groaning sound is what they can sound like while creating max pressure up to 1600PSI.

Actuator only runs when you apply brakes.

7 way plug molded or replaced? Replaced has REMOTE chance of power being incorrectly applied to brakes. And that’s a BIG IF.

If yours has the factory installed E/H system (shown below), they should be rebuilding at no cost, right?

I had the actuator recall test performed and at that time it passed. So it was not a guaranteed R&R it had to fail the test. And the test was to drill a hole and see if fluid leaked out.

Hopefully these recalls were addressed but I try to bring them up when a new owner raises a question.

And that hose looks like the original config looks good right? Now mount wheel lower trailer and suspension goes up and hose gets shorter and kinks at caliper connection.

Exactly.
Yep. J/C did the "test" on my original Actibrake, and it passed. Brought it home, parked it in the driveway. Failed the next day (fluid leaking out hole).

The drill here test instructions were pretty weak. Low grade images. My shop drilled thru the side of the case not thru the bottom.

It later failed and I drove home w/o trailer brakes.

Replaced with Carlisle actuator.

Decided to take old one apart. Had to use saw to cut cases apart.

Found that test drilling drilled THRU a circuit board.

Brakes are working great.

Your hose pic is poster child for that problem.

Although I don’t have these disc brakes, they look to be a problem child..sitting and absorbing moisture from the air, and rusting internally....our old cars with hydraulic brakes, have to be pumped at lest a couple times a month to keep the rust away...brake fluid does evaporate and absorb water....

I've found bleeding is required once a year. YMMV. The fluid isn't 'out of the bottle' new, but it's not bad. Only slightly darker.

Pulling all four wheels and bleeding takes 60-90 min maybe. Yeah, it's more maintenance but I wouldn't trade it for electric drums, and it can't hurt inspecting your running gear regularly.

Goes nicely with rotating tires and pull pads to clean anchor points and dab grease on them.

Yeah I’ve spent some time working on them, no make that learning them and fixing a design flaw (short hoses) with my own version but no way am I going to change them to drums.

I know I have brakes it’s stopping like a matched set of TV brakes and AS brakes.

Hydraulic brake blues

Thank all y’all so much. They plan to do the drill test soon. It seems to me that the controller is defective as the hydraulic pump runs while the RV is sitting unhitched.

Comment? Joe

If it's an Actibrake controller, the company has been out of business for many years. You have no recourse other than to purchase a new replacement from a different manufacturer.
