I guess I cut it off too quick not giving bubbles at the beginning of the lines to make it to the calipers/cylinders. Brakes are much, much better. Not perfect though. I think the booster may be going out. Pedal still travels halfway to the floor.
Also, I had a small leak from the reservoir hose. Fixed it but the fluid filled the rear lower switch plug with fluid. Emptied it out. Now my warning light doesn't come on and my brake lights don't work. Could the brake fluid have ruined the switch/plug?
Boosters either give boost or do not give boost. They are not responsible for a pedal that goes halfway to the floor.
Pump the brakes quickly with the engine running.
Does the pedal travel less after a couple of pumps? Wait a minute. Now apply the brakes again. Soft again?
Now apply the ebrake. Pump the brakes again. Does the pedal travel less? And does it now stay in this shorter travel
even after waiting a minute?
If the pedal remains shorter travel, you need to adjust the rear brakes.
If the pedal goes soggy after your wait, with the ebrake on, you need to bleed again.
