I have replaced the brake booster and master cylinder and brake lines, I have bled the brakes; back passenger, back driver, front passenger, front driver. About six times and when the car is not started I have partial pedal but when I start the car I have no pedal at all.
Do you

Hello,

This could be a problem with your vehicle's brake booster check valve or a leak on the vacuum line going to the brake booster. Have an assistant press on the brake pedal and listen to the brake booster vacuum line and check valve for any audible leaks and then get back to us with what you are able to find out.

Thanks,
Alex
