The best solution is to crack open the bleeder screw (not the brake line) and slowly push the piston in with a C-clamp. Be sure to use something between the clamp and the piston, such as a piece of metal. On some vehicles, you could even use the old brake pad. Another option is to use a large socket centered inside of the caliper. Be sure to close off the bleeder prior to assembly. After you've reassembled the brakes, press down slowly on the brake pedal, about 1/2 to 3/4 of the travel, as many times as necessary to restore proper pedal. Top off brake fluid as needed. Also, this is an excellent opportunity to replenish the brake fluid to the front wheels. Use a syringe to draw out as much old fluid from the master cylinder as possible, fill with new fluid, and then bleed each front brake until new fluis comes out. The use of a piece of clear plastic tubing attached to the bleeder screw allows you to observe the color of the fluid, as well as minimizing mess. doug
