Brakes Broken On The Road

I have a 2017 Coleman 300tq Toy Hauler with 4400# Lipert axles.

When I pulled into our campground last Tuesday I felt a serious tug on the trailer brake. I checked all the wheels with a temp gun and the right rear was 30 degrees hotter than the other 3.

Waiting until today (tell me about it) a day before we are due to check out I thought I better give that wheel a look.

With the wheel off the ground I could tell there was a problem when I spin the tire. Pulled the tire and drum I could see that things were bent out of place. The brake pad arms seemed out of position and the backing plate was bent out.

Don't know how it happened but it's Sunday anybody that is open today including camping world does not have the 10 inch backing plate with brake components for 4400# axle instock.

They had 3500# component which looked the same but when I checked to see what the difference was I found that the backing plate 4 bolt mounting holes are slightly different that the 3500#. The too is the same but the bottom a little wider.

When I look at the mounting holes I see no noticeable difference but when I tape measure I come up with 2 13/16 center to center. But my imperfect measuring tape may differ by 1/16"

Monday when a local trailer parts store opens I am going to try and get a total backing plate and brake component replacement for 4400# axles. I will be taking my old one with me.


Now. if I can't get the replacement part I need I am thinking of straightening out the backing plate and putting it back on without the brake components until I get somewhere that has the part I need 200/300 miles. and just running on the 3 good tires that still have brakes or Should I cut the power to the rear axle all together and just run brakes on the front axle.

Any thoughts.

Wish I would have got started on this sooner.
