Well, being new to the LT glad to hear this is normal. I got a helluva racket every time I apply the brakes. Sounds like the pads in the rear caliper are slapping around loose or a sound like the caliper bolts were loose.
Squeal from hell too. Anyhow, I pulled the caliper off, all bolts were tight. I applied Wurth Anti-Squeal spray to the rear of the pads. Then put them back in and re-mounted the caliper. Then I was playing around with the rotor... all loosy-goosy and I'm thinking what the heck? Now I read here it's normal. Well the "bolts" that hold the rotor surface onto the rest of the rotor hub look like big rivets no way to tighten them... the whole floating rotor thing. I'm wondering if this is my clackety clack noise when I hit rear brakes at a stop light while going real slow.
Hopefully the wurth spray fixes most of my squeal issue. I'm gonna spray that stuff on the front brake pads as well next fix-it-session.
I left the rear wheel off, gonna replace the tire this week, have a new one on the way.
