I have a brake problem that's driving me nuts.
I have a Titan model 60 that I bought from you guys in 2013 and 4 less than 1 season old drum brakes and drums. I got them from you in July last year.
The problem is the wheels are locking up after I brake. Its random sometimes its the front right sometimes the left rear whatever.
I have lubricated the brake shoes at the backing plates and also the hitch actuator. Bleed and adjusted the shoes multiple times trying to get them to work. They do release when I back up. Pull forward stop and a wheel or two will be locked and dragging random.
When I have the wheels up to adjust the brakes the brakes will lock and release when I pump the Master cylinder but not with the trailer on the ground.
So what should I do next?

OK I may have found something is the shock absorber in the actuator supposed to expand on its own after it's collapsed? When I collapse it it stays collapsed is it supposed to expand on its own?

No the function of shock is to be a cushion in both directions so it doesn't slam. The problem you are experiencing sounds more like wheel cylinder issues not the actuator. If it was the actuator and the brakes were functioning correctly it would be a problem at all of the brakes.

x2 And possibly weak return springs. Are you sure the shoes are the correct size for the drums?

Well I still have the same problem after changing out the wheel cylinders I still get brake lock on a slow stop with no release unless I back up. I have lubricated the shoe contact areas and adjusted the shoes to 10 clicks off lock up. I have bled for he brakes until all the bubbles are out. As a bonus I replaced the shock in the actuator.
I also took apart the actuator to check for wear and lubricated seems to be working well.
I also took apart the wheel cylinders I replaced with new to see how bad they were. Well except for the grease being washed out from under the boots the boars looked good. They came apart easy and we're still in good shape after all.
So all that is left is the Master cylinder I guess.
Funny thing is when I use a screwdriver to bleed the brakes they stop the wheels and don't lock up they seem to release just fine.
But when I put it on the ground I can't get out of the driveway before they lock up.
Any ideas would be helpful, I'm out.

Do the pistons on the wheel cylinders point towards the front of the trailer on the wheels locking up?

The brake hardware is directional, meaning that it only work correctly when installed on the correct side of the trailer. Similarly, the shoe/lining must also be installed correctly.

On surge systems, the (top mounted) wheel cylinder piston must push toward the front of the trailer. the shoe with the shorter piece of friction material (primary shoe) or brake lining should be located on the front, and the shoe with the longer piece of friction (secondary shoe) should be on the rear.

Improper installation will cause issues.

'Just tossing ideas out there to try to help.

Seems you've exhausted the possibilities. You mentioned that you adjusted them several times. Are you adjusting them so there is a slight bit of drag? If not, the piston in the wheel cylinder might be extending too far and could be handing up in the cylinder. Not a high probability but I've run out of ideas.

Being as they don't lock when raised look at your hoses they could be pinched when trailer is on the ground or flexed in a way that fluid won't return. Best of luck with finding your issue

Believe it or not I know precisely what you are experiencing. I had the same problem last year, when I was scratching my head about the possible causes and got tired of changing wheel break cylinders on my passenger side trailer wheel. Never found what caused the wheel to lock and overheat, so I just disconnected the break line from main cylinder and said the hell with it. Later on I found out that some manufacturers don’t even install breaks on their new boat trailers. Ever since I had no problem with wheel on either side getting locked. Good luck finding the real reason for that problem and if you do I would be interested to know what it was.
