I just bought my 2nd SOHC 750 and have the same problem with both. My front brakes don't grab. In both bikes, I have rebuilt the master cylinders, rebuilt the calipers and adjusted the caliper to the rotor so that it is just a partial turn from rubbing the rotor. I both cases, the master cylinders were all clogged up and the calipers had large amounts of glop in them. I cleaned up the pads, which had some electrolysis between the aluminum caliper housing and the steel pad back. I replaced the upper and lower rubber hoses. I bled the systems with Amsoil brake fluid and have a firm feel to the brake lever.......but the brakes don't stop the bike well.
I have other disc brake bikes with which I can lock up the front brakes. Not so with my Honda CBs. You could not possibly lock up these front brakes. The pads in my K5 are newer and the pads in my K1 might be original but have lots of pad.
I have a '71 BMW 750 with drum brakes that stop better than my CBs. Any feedback? Are all SOHC CB750s poor this way? Are there new pads that work better than the OEM pads?
