One piston pushes on the piston-side pad, the other piston pushes on the yoke which pushes on the outer pad. Either the yoke is frozen or the piston is frozen. Either will prevent the pad from being pushed against the rotor. > After we finished up, on the test drive, the brakes started > smoking on one side.

However, I have had the problem where the lever that enters the piston assembly binds. When this happens, the handbrake will not release and the brakes will burn. You should probably remove the yoke and handbrake lever, clean up the shaft on the handbrake lever and replace the seal. That should get it working freely again. John
