Finally had a day off to work on my rear brakes. Needed a new caliper for the rear right. Installed it and tried bleeding the brakes. With bleeder screw closed, had my helper push brake pedal to the floor. Loosened bleeder screw. Heard air come out. No fluid. Closed screw. Helper released pressure on brake pedal. Repeat the process and hear air again but no fluid. Repeat, a tiny bit of fluid. Repeat, no fluid. Repeat, tiny bit of fluid. Stop.

Now I just went into the car and pressed the brakes. minimal resistance. Pumped a little bit and couldn't get any more resistance. Started the engine and pressed the brakes, no resistance at all.

Is it just a matter of continuing the process until we start getting some substantial amount of fluid being forced out?
