I bought a used 14ft Tandem Trailer for my 2210 today. It was built in 1998 and looks in good enough condition. But tell me, how do I check the electric brakes when I pick it up tomorrow? Do I just trip the safety switch and try to pull it? Is there a better way to know that all is working before I take it off the lot?

HELP!

I currently have three trailers with electric brakes and have traded or sold three others.

None of them would lock the brakes with the break-away switch or by manually manipulating the brake controller. But they would all smoke 'em in a panic stop.

The only thing I can suggest is to drive it. If you can feel the trailer dragging the truck toward the end of each stop on a paved road...... or if you can get them to lock up on a gravel road..... then they a probably working OK. ....

The brake controller in your truck should have a manual manipulator that you can actuate only the trailer brakes. You should be able to slide the trailer tires on gravel doing this.

Also on the controller are two other adjustments that can be used to adjust sensitivity (coarse/fine). You will need to adjust these to get the right brake force. I usually change mine from empty to loaded conditions. If set too heavy, the trailer tires will also slide on pavement.

To test the trailer's battery, pull the safety cord. When you move the trailer, the brakes should be on. Some slam them to lock, others just put a drag on them. You should periodically check this to make sure it is in working condition. A weighmaster can ticket you for a dead brake battery.

I have several trailers, each requires a different adjustment. It is a piece of cake once you are accustomed to using them. ....

Thanks guys! That's just what we did. Pulled the pin and set the control to a high setting and the wheels locked up in the gravel. By the way the battery was dead too and it was the truck's power that locked the wheels. We replaced the battery now and all is well.

Thanks for the sound advice. ....

Sorry to bother you guys again, but I've got a "rookie" question on trailer axles. I took the flooring off my "new" used trailer this weekend. Now I'm replacing all the wiring as some had cracked insulation.

But I noticed that both axles have a slight (and equal) bow to them. They are "drop" axles and do not look as though there was a problem. I'm suspecting that they are bowed (up) and flex down under load. Am I right??

You are correct. That 'bow' is called a 'crown' and does the same thing as the crown in a piece of wood, it flattens under load.

In the case of your trailer it is to maintain the wheeels in a vertical position under load by ensuring that any flex only brings the axle back to flat.

Best of luck. ....

Thanks Murf. I thought I was right, but it always pays to ask questions of the experts! Thanks. ....

Yooperpete - I was re-reading this thread this morning and focused on your note about getting a ticket from a "weighmaster". I never considered that I might need to stop at highway weigh stations if I travel main roads. Will I need to do that pulling a tandem trailer behind my Suburban? ....

No you don't have to worry about that! Your GVW isn't high enough to bother with that. But every now and then a weighmaster or police officer has a bad day and needs to get rid of some frustrations. Don't give them an excuse. Just make sure (all) your trailer lights are in working order and that you use turn signals, etc. and keep the unit under control. ....
