    Exclamation Help New here 74 Brake Bleeding issues

    Hi I have a 1974 stingray. My husband is an auto mechanic and we do all our own work on all our vehicles. We recently have done work on my car and cannot get the brakes bled. We replaced the master and proportioning valve, the rubber lines and all 4 calipers. We have bench bled the master and bled the brakes everyway we know possible and still no brakes. There is not a lot of corvettes around here and not really a place to take it that we trust. Any help would be greatly appreciated as I really hate her sitting up on jackstands in the driveway.

    Welcome to the forum

    Did you bleed the rears from both bleeder screws? Offhand I don't remember which should be done first. Many people miss this.

    I have seen new masters and proportioning valves be bad right out of the box as well. And there could be small leaks around the bleeders themselves.

    Here's an article that may help:

    Normally you start with the bleeder farthest from the master cylinder and work your way to the closest.
