Ram-Lin Trailer questions

[homer12]

So, I recently was sort of shocked to see what looks like no suspension under our 2004 Ramlin trailer. Am I missing something or do they rely solely on tires for suspension?





My old MC trailer had leaf spring so I was expecting that I guess.

What tire pressure do you run like this?

Also, is there a better way to change brake fluid then bleed it all out the caliper banjo bolts?

Called a torsion axle suspension. There is pretty much a giant rubber bushing in the axle that is under torque that is holding up the spindle arm. that rubber flexes to provide the "suspension" over bumps.

Tire pressure should be listed on a tag somewhere on the trailer, if not, use the pressure listed on the tire itself.

As for bleeding the brakes... not really.... I was so close to buying a mighty bleeder to pressurize the system to do it by myself, but eventually talked the other half into pumping the master cylinder via the hole in the bottom of the actuator. You can find a bunch of videos on the youtube on bleeding trailer surge brakes.

Hope this helps,

Tim

For bleeding the brakes, buy a small pump sprayer, take the wand off - you will have a threaded end near the trigger. Get yourself an extra brake actuator fluid fill plug. Drill and tap the plug the size of the threads, if there is a small vent hole you'll need to plug it with something (I used a small hook point), then add a jug of fluid to the pump sprayer and there you have a bleeder system. Just did mine last week after installing a new actuator and it worked well. Or you can buy a professional system.... bleed the furthest away from the master cylinder first. I actually flushed my entire system good and after making the the bleeder system, took me about an hour - by myself, taking my time..... Nice to have brakes again.

If it is a 'C' load range tire it's most likely 50 psi, if you have 'D' range tires, most likely 65 psi.

Thanks for the help guys! Very interesting on the axle types. I've heard of those and now I see what they are I guess. Will probably flush brakes this summer while boat is off or this fall.
