I've been having a problem with my brakes for awhile now, even before I got the LT kit. It's very sporadic and the rotors & pads are new. The calipers have about 168k miles on them.
Sometimes I'll be driving and say coming up on a red light or stop sign, and as I start applying the brakes before I make a complete stop I'll hear this grinding sounding like metal on metal. Then it will be fine for awhile maybe couple days, then start grinding again. Like I said pads are brand new rotors were changed about 3 months ago. It happened before I changed the rotors and pads as well but they had plenty of meat and I took it to a brake shop and they couldn't see anything wrong. They even drove it around and braked hard for me but it wouldn't grind for them. It's progressively getting worse.
Maybe I need new calipers? Not sure what it could be at this point.
Thanks for your help.
