Soft pedal

[007gn]

My power master started leaking so I removed the unit and converted over to a regular brake system from a 79 Malibu . I'm using a new billet vacuum block n I purchased a new master cylinder . The only part that's old is the brake booster. I've bled the brakes all the way around. My pedal is soft n the brakes r worst than the leaky power master unit was stopping . Oh n I do have a 215/220 Hyd rllr cam with 1.60 rllr rockers in this engine ... What could b the problem n what did I do wrong ? The booster looks the same as those I see on 89 turbo t/a s. My brothers car has been converted to vacuum brakes n his car stops better than any power master I've ever felt. Any helpful info or suggestions please.

Did you bench bleed the master cylinder

No I didn't bcoz I had to bleed all 4 wheels anyway.

Step back bleed the master, then rebleed the rest. Sounds like you have some air in the system.
