{Chrysler 300} 300K Ram Brake Problems

Hi to all

A little background. Approx 2 years ago I was having leakage at the master cylinder and the brakes felt weak. I figured it was time for a rebuild. I removed both the master cylinder, the remote brake booster, and the slave cylinder and took them to Power Brake Exchange in Pittsburgh for rebuilding. They did find a broken spring in the remote booster and were able to replace it as well as the additional seals and such. They provided a test report and it showed the booster providing 300 psi? (I can not find the paperwork at this time but I believe that was the number.) I got everything back home and got back together. I also replaced the front wheel cylinders, shoes, and front hoses. Also, replace the vacuum line from the intake to the booster with the correct type of hose. I followed the service manual for the bleeding order of the system more than once.

Here is the problem. I have brakes when the car first starts up. But after a couple of stops, the brake pedal starts bottoming out and the brakes do not hold. I was so frustrated and fed up that I just put the car away.

In the meantime, I have become a cancer patient and I would really like to get this fixed and possibly enjoy the car this spring/ summer while I can.

I have considered taking the car to the local Chrysler dealer whose ownership is into Mopar Muscle as I am not sure how much I can still do.

Any thoughts or suggestions are appreciated as well as any shops in Ohio that may be able to work on this.

Thanks in advance
