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. |

Thanks. The calipers are new from PMB. The rotors are not new, but by rotating the wheel they do not "feel" warped out of spec.
Starting to think it's a bleed issue. On the rears I found I have to manually hold the e-brake in the release position during bleeding. So much for 1 person speed bleeding. (IMG:style_emoticons/default/dry.gif) |

(IMG:style_emoticons/default/dry.gif) I was able to bleed mine solo pretty quickly after installing speed bleeders, and this was after installing a new dry MC. The Motive pressure bleeder only helped me with getting fluid through the MC. The old pumping the brake method worked fine to bleed the system though. I don’t understand your comment about having to hold the e-brake in the release position. Is your venting clearance on the rears set correctly? Are your e-brake cables configured correctly? |
