Hoping for some advise .. I've just rebuilt my rear brake caliper after it had seized , smoked the pads, melted the brake line where it entered the caliper. I installed new pads, brake line and seals. Using a Mitivac I drained the old fluid and added fresh but for the life of me I can't get any hydraulic pressure under the pedal. It almost feel as though there is nothing in the master cylinder but I know I was drawing the fluid from the reservoir to the bleed nipple. If I spin the rear wheel I can hear the pads dragging and can see that they are touching the rotor. Another weird thing is that I can't get the rear brake light to turn on. The front works, signals are fine, headlights etc., all the fuses are good. Is the switch activated by pressure ? So, before I pull the caliper off the rotor again to check for obvious owner errors has anyone run into issues like this.
