Trouble shooting the fact that I have zero rear braking with a new master cylinder and proportioning valve. Have a hard petal even with the left rear bleeder cracked open, and no flow. Think I must have a bad proportioning valve. Got another one ordered, and that doesn't fix it I will look at the rear rubber hose next. The valve trip rod is in the middle and the light is not on, and I have verified that the brake light works. Going to charge the ac tomorrow while I wait on brake parts.
