Rear brakes(?) squeak under load
I had noticed a while back that when reversing uphill (like my driveway) the rear would squeak just a bit. It also seemed that backing up, I would hear it more often. I never heard anything squeak if the truck was moving forward.
Once it reached the point of annoying, I did a rear brake install, cleaned everything and reassembled it. Everything has been working great, no noise or anything for about 200 miles or so.
I went and picked up a trailer this weekend. When the trailer is on, the rear brakes squeak a lot whenever the brakes are applied. It seems strange that load would cause the brakes to react this way. The trailer is small and had nothing in it, so I can't imagine the load was that much.
I tried searching around but couldn't find anything like this, so I thought I would toss it out here and see if anyone has seen anything like this?
