Question on brakes

[Bdawg]

We have a 2011 Rockwood Signature Ultra lite 34 ft tow behind. Problem with rear brakes. Left side works fine, ample power going to left side. Right side, magnets hum but wont lock up wheel. Have taken apart right side, lubed and replaced magnets and adjusted brakes. Still no brakes. Replaced wire completely from left side to right side, still no brakes. Amperage on right side same as left side. Cleaned ground on front of trailer, still no brakes. Any ideas???

Maybe they need to be adjusted.

All brakes have been adjusted

When you replaced the wiring did the ground wire run back to the junction box or was it terminated near each wheel on the frame? If it was terminated near each wheel, I'd check all the grounds and clean them well. Also, what gauge wire is ran through from the left side to the right side?

[Bdawg]

Ground goes back to junction box and replaced wire 14 gauge that was on their from forest river

Is the right side the heavy side?
How did the hubs look when you replaced the magnets? Were they shiny on the rubbing surface? If they were shiny, you may want to pull them and have them turned so that they have a roughened surface and then burnish the magnet against them properly.

I think I'd remake the connections.

Left side is heavy side which is on drivers side and that's where the brakes lock up good not so on right side when replacing magnets on right side yes inside drum shiny with slight groves from old magnet all connections have been checked and rechecked

Today I took left side magnet and hub and put on right side and nothing still just a hum those parts worked fine on other side next went to junction box disconnected left side and installed temporary line from their to ride side brakes still just humming no brakes next even though grounded thru junction we added another ground to right side as a last straw still nothing but hum no brakes any ideas greatly appreciated

Did you look at the brake shoes to see if they were glazed? If they were, the magnet and lever mechanism will work fine but there will no (or very little) braking power.

[Bdawg]

What do you mean by being glazed I took sand paper to clean shoes up they looked ok

Controller?? I didn't see mention of that. Some of the old ones may not be compatible with 2 axles. Prolly not it, but it might warrant a check

[Bdawg]

The brakes were not shiny if that's what you mean

[Bdawg]

The controller on the truck Chrysler installed checks out had at dodge dealer 2 weeks ago the truck is a 2011 dodge ram Laramie with 20000miles original miles almost new

[Bdawg]

Had that checked out their

Did they ever work? If you took an Amp draw to each side, then I say the magnets are working correctly. I would look at the actuators and verify the shoes are getting spread. The activated magnet drags on the drum, the hum you hear, causing a lever effect as the drum turns to a fulcrum that spreads the brake shoes.

If they did not ever seem to work, then I would verify that you do not have some left side parts mixed in on the right side. Rotation will be backwards and brakes will not activate. Test this, rotate the affected side backwards and see if you get braking.

[mwdilday]

Sounds like adjustment to me.

[Bdawg]

Adjustment has been done numerous times

Have you gone through the "Burnishing Procedure" that is listed in the Dexter Manual? Youroo!!

Did someone recently install new brakes? Loaded assemblies are right and left.

Good point even factories make mistakes
