I just bought my 2001 1500 Quad Cab 4x4 and have drove it on the freeway and city with no issues. I even towed my Honda back when I picked up my Truck. It has 186,000 miles on it. I had no problem with brakes or motor. I go to the store yesterday and hit the brakes and the front right tire locks up. Not having an issue before I think drive it a short distance at a slow speed and try again. Repeatedly lock frot right tire and seems like the other brakes are not working? What gives?

 

Pull the wheel off and check for anything abnormal.

 

x2..caliper piston could be shot..if it seems like the others aren't working cause the fr right is kinda doing all the work..
but gotta pull it check wear on both sides (drivers/passenger) is rotor wear even...
