      The brake booster will not give a low pedal unless it has an incredibly large diaphragm tesr, coupled with a very bad MC rear seal.

      first step. Check mc. Observe the rubber seal in the cap. If it is swelled up, look no further; system has been contaminated, and mc, all rubber brake hoses, calipers/wheel cylinders need replacement. Second step check the rear of the master at the booster. If there is any wetness dropping from master at the booster, replace master. If all of that check out, move on.

      next step is to pinch off all hoses. I strongly suggest only using appropriate hose pinching pliers, but if none available you can use locking pliers. But be careful! Clamping too hard on hoses can damage hose internal lining. Once you've clamped off the hose to each wheel, depress and hold the pedal. It should drop no more than an inch, and should not fade downward. If it drops more than an inch, but does not fade any more, it'd possible you have air trapped in the system....consult manufacturer for proper bleeding sequence. RR, LR, RF, LR isn't aways the proper bleeding sequence in every vehicle. If the pedal continues to drop, suspect either bad internal master seals or a rusted/corroded/cracked brake line or hose.

      Replaced the master cylinder with a rebuilt one. Bleed it at the mc brake line connections, loosen bl conn push pedal to floor then tighten bl conn, let go brake pedal, then each wheel per OE specs rr lr rf lf, repeat 5x's. Didnt help so I did it all again. Stiill the same. So your saying it could be air coming out some where after the brake hoses. I will try that test and post results.

      I think I may know why your brake pedal has an issue. this has to do with the abs unit. first off, does your master cylinder have an abs unit mounted directly to it? I know some buicks use this design, and the abs unit must be detached, opened, clock back the gears, mount to new master, then reassemble. hopefully you do now have this setup, as it is a pain to deal with. second, did you bench bleed the master before putting it onto the car? this step is of utmost importance to remove trapped air.

      Thx, I did do a replacement for a the frnt rght brakeline, which attaches to abs box. So being bubble conn bl I had to conn an adapter for the flare bl. The abs bl conn stripped, I mix welded the adapter to it, next day conn it & it never leak there. So I dismissed the abs as a culprit. But in the winter it had a sim issue when sand& salt got between the abs sensor by the wheel conn to lower control arm. I clean it, reattached & breaks worked fine. Does a faulty abs system cause pedal to floor?

      Clean the outside diameter of the wheel hub - and especially where the rim seats - of all dirt, grease, rust - even a slight amount may prevent the wheel rim from properly seating on the hub center.

      I did, with a wire brush. That also didn't work.

      The specific replacement part and the exact ABS control module to purchase- depends on the application and combination of options.

      Does your vehicle have AWD (all wheel drive) or two-wheel (front) drive? Does your vehicle have traction control - option NW9? Does your vehicle have tire pressure indicator system - option UJ6? Does your vehicle have 4 wheel disc brakes - option JL9 - as example.

      These parts will fit - based on the specific vehicle options and application;

      ACDELCO Part # 19302004 {#15269779}
      AWD; LOW TIRE PRESSURE IND(UJ6)

      ACDELCO Part # 19302014 {#15269789}
      FWD; 4-Wheel Disc ABS brakes(JL9), ELEC TRACTION CONT(NW9)

      ACDELCO Part # 19302006 {#15269783} AWD; Except Low Tire Pressure Ind(UJ6)

      ACDELCO Part # 15269790 GM Original Equipment Brake & Traction Control
      FWD

      ACDELCO Part # 15269784 AWD; Except Low Tire Pressure Ind (UJ6)

    I've had the drums looked at also. When the car gets hot, the noise appears.

      Check the power brake booster, the air could leak from a broken air vacuum.
