Question---how much "drag" if any should there be between the pads and the disc, when the peddle is not being applied? I have installed a 2 pound residual check valve in the line leading from the master cylinder to the front disc brakes. (This is what is recommended for a master cylinder under the floor application.)---It is installed with the arrow pointing in the correct direction---away from the master cylinder. I haven't bled the brakes yet (I'm waiting for some "speed bleeders" from Russell)--however, when I pump the brakes up the pads definitly grip the discs and hold them---but after I release the pedal and the pads "back off" the passenger side ends up with very little "drag" while the drivers side has quite a bit of "drag" on the disc. (I can still rotate the disc by hand.) The mounting bolts and bushings are well lubricated with silicone base grease (which is recommended.) ---is this unequal drag just because everything is brand new?
