This is a '73 with rebuilt calipers and proportioning valve. I first gravity bled the brakes in the recommended order. I then switched out the top bleeders to speed bleeders and bled the brakes twice waiting a couple of days between the first and second speed bleed. So far I've used roughly 1.3 L of brake fluid.
Questions: 1) My front left caliper seems fine, but the front right seems to bind. I cannot get a shim between the pad and rotor. When I spin the wheel it goes around maybe a bit over one revolution before stopping. Is there a way to adjust this? Will the clearance set when I drive the car and start braking harder? Is this a result of air in the line? (Car is not driveable now, no engine) 2) When I did the gravity bleed with the normal bleeders brake fluid wept from the bleeder threads. Should a sealer be applied to the threads to prevent this? The speed bleeders seem to have a thread coating and do not leak from the threads when open. |

If you have a dial indicator and magnetic base you can measure the run out on the rotor. The money is well spent on the Motiv product.
