i dont know if my truck doesnt like to go fast or wat but the rear brake caliper is stuck... the only other thing i could think of is the emergency brake being stuck but im not sure. My mpg is already low enough, i dont need this helpin out. Any ideas how to fix it? 2005 Powerwagon

 

sweet a PW ..post pics then we will help .

 

Can you tell if it is the brake or parking brake? If its the parking brake you might be able to get away with adjusting the star on the bottom side of the parking brake.

 

you should be able to chek out the pics in my profile and i cant tell if its the parkin brake or not

 

block the front tires,
put it in neutral (trans or transfer case),
jack up both back wheels and turn them by hand,
you should be able to tell if the wheel is sticking and if its the parking brake or caliper
