Two brake related things

Hi all, two questions. I have a tekonsha primus brake controller. Had it working great for about a year. went to use it this last time around and sped up to 25 or 30 mph and pulled the bar all the way one way to see if the trailers tire skid and they did not. adjusted it up and they didn't skid. You can definitely feel the trailer brake and pull the suburban down. Ended up to max power and still no skid. Now when I go back to least power I don't feel the brakes even engage. So is there a way to test the full ouput of the controller? I jacked up all four wheels and they were dragging slightly.

Second, when I went to jack up the trailer axles I went about 1/3 way in and as it jacked up it looked like it started bending so I let it back down. Never got it off the ground. I hope its not bent.

Third (I know I said two). When I checked the brakes I checked the bearings too. They may have had 1/16 to 1/8 in play in them up and down. All were about the same. I kind of want to take a turn on the nut but don't want to overtighten them. Is this too much play.

BTW re-setting up a reese dual cam to a e350. That front end only raised a 1/4 in from stock. What is kind of suprising is that the wdh from the suburban to the e350 barely changed at all.

Getting ready for a outer banks trip.

Thanks
Bill
  • Old-Biscuit, how long before I see the wearing on the edges? 1000 miles? few thousand? Or could I see it before go 250 miles? Also, is this going to cause it to wonder all over the road or sway a lot?

    Thanks
  • Ok, that is what I was afraid of. Just wasn't thinking. Oh well, you live and learn.

    Thanks, will adjust brakes.
  • It souns like your brakes are simply out of adjustment.
  • Need to adjust brakes.......

    NEVER jack up trailer 1/3 of way end on axle. You can jack it up using axle IF jack is placed under area where springs are attached. IF not there........use frame. You MAY have bent axle. YOU will need to monitor tire wear. Outside wearing indicates axle bent up.

    A little end play is OK....it will minimize when bearing/spindle heat up.
    Over tight and bearing/spindle will get damaged
