New breaks

i put new breake on my truck and the back right side its like i can jack up the truck and cant speen the tire

Help us help you. Disks? Drums? Can’t spin the tire? Did you follow the directions and use the proper tools? And follow the correct procedures to install brakes? You’re not only endangering youself but everyone else on the road as well if you don’t know how to install brakes correctly. I suggest you get it towed to a mechanic that specialises in braking systems. If the tire doesnt spin freely the brakes heat up. Hot brakes are never good and can blow out a tire if it gets hot enough…

it is disks breaks i can drive the truck at about 1000 rpm the truck will move
