Ok, so I called and can get rebuilt Calipers at a reasonable price.....Lets assume I get the brake lines/hoses off each bad caliper with out snapping off [always my problem area] and the rebuilt calipers installed. The only area I feel hesitant about is bleeding the system with out the aid of a specail brake bleeding tool. Can this system be purged of air with just the conventional method of pumping the pedal and opening the bleeder of each caliper?
Thanks guys for all your input.
