Re: Rear Pads @ 13K?
I'm sure there are many threads about using both brakes, and I believe your model has "linked" brakes. If you apply the front or rear only, it applies a portion of pressure to the opposite brake that was not squeeze/pressed.
70% of braking power is on the front brake; weight transfer during the decel results in the front brake having more traction and less weight/traction on the rear tire. Some folks here predominately use front brake; given the wheelbase of the LT, a stoppie is practically impossible.
This may explain why your rear brake is 80% used up: you are only using the rear brake and getting only "some" front brake stopping power as a result of the linked brake system.
Practice using both brakes during stopping or slowing. Of course, then, your front brakes will wear more but then, you have twin discs up front.
