Re: Old Girl (aka Project Underhaulin)

Buck, check the brake pedal clevis. When the brake pedal is in the full released position you should have aboit 1/4" of free play before any brake pressure is applied to the push rod. This will allow it to be in the fully "released" position when you let completely off your brakes.

Also, the original hole where it mounts to the brake pedal rod itself, drill a hole 1" down from the original mounting point. This will not only give you a better pedal feel, but a more linear lateral "push" stroke as the pedal moves through its range of motion.. then likewise a full pull "off" when you let your foot off the brakes.

To me, it sounds like residual line pressure. In short the calipers aren't fully releasing allowing enough space between the pads and rotors when it's just rolling. The brakes are being slightly pushed at all times if that makes sense.

Ask me how I know.. Lol. I'm fighting this same issue.
