Looking to replace the front rotor/hub assembly on my 2 WD. Been looking on Ebay. Has anyone heard of or bought from Calahan ? Are Powerstop a decent brand ? Thanks. Truck has 71K on it and the rotors are worn. To have them machined takes a special bit and the dealership wants over a hundred dollars to do it. Thought it makes sense to replace the who hub/ bearing and rotor would serve better. Any opinions are aprreciated.
