We have replaced everything to do with the brakes, vacuum booster, master cylinder, etc. We have done a complete bleed and still have no pedal when we start the car. Any ideas

    and then what? do the brakes stabilize (get better, pedal comes up)? if so look to proportioning valve allowing too much pressure to the rear brakes. if the pedal stays spungy and low, did you try adjusting up rear brakes (if drum type)?

Hi Friend:

#1) Check and make sure your Power brake boosters Hose is not Cracked or just not a tight fit going to Intake.

#2) Since you Have Rear Drum Brakes You might have left to much Brake to Drum Clearance==Ajust rear Brakes out to Just give you good clearance to slide Drum Over Brakes.

#3) Check all your Brake Lines for Possible leaks.

#4) CHECK to make sure your Accuating Rod from your Brake Pedal to your Power Brake Booster is in the Rear of Boosters Piston that whenb you apply brake its Acctuating the Power Booster.

#5) Also did you bench bled your Master before instaling? If not you'll have to bled your master clylinder 1st, and then Start at farest wheel from master cylinder and work your way to the brakes on front Drivers side.

#6) only other thing that comes to mind is your Anti Brake Module.

Hope this has helped you ,PLEASE let me know by Voting For the Soultions i've Given You.

Thank and Good Luck d_hubbs

You changed the master cylinder and vacuum booster and have no leaks anywhere, but did you bleed the entire brake system after you did this work? A little bit of air in any of the lines will make the brakes ineffective.
