Replaced the oil bath hubs,rotors & breaks on the trailer for the Ranger 188vs. Put the original specked brakes for the TieDown Vortex hubs i got from Ranger parts dept. Installed the new brakes & after putting the calipers back on the rotors there was a lot of play between the brake pads & the rotors. Is this due in part cause the piston in the tongue hasn't been actuated or were the brakes installed incorrectly?
