info Chevy P30 hydro boost brake/power sterring bleeding

[1530004]

I am looking for info on repairing & bleeding the hydro booting brake system by a mechanic on my 1989 Coachmen 23 ft. MH. He has replaced the leaking brake lines on the frame rail below the motor, replaced the rt. real wheel cylinder & master cylinder as well as replacing all the brake fluid and same wheel seal. Bought a bleeder system and used it but still can't bring the brakes up to snuff. Also I have a friend who is a retired certified Chevvy mechanic and currently teaching a DBSC and he is attempting to find an answer. I found a post by radardog 01/28/09 reffering to a post by "OLUSEDBEAR" to try turning the steering wheel back & forth with the engine off to prevent further problems?? I have not been able to contact either of them to gain further info. Thanks, Dick

Turning the steering wheel is to bleed the power steering system.

The P-30 manual says to use a vacuum bleeder to bleed the brakes.

After replacing my brake hose I used the pump the pedal method and that worked OK.
