Brake pedal slowly sinks to floor and works better if pumped. Installed a new master cylinder, new rear brake wheel cylinders two times, front brake pads and a brake fluid change.

Hi,

It sounds like you still have air in the system. On these vehicles, I have found that you need to use a brake bleeder at the master cylinder to pressure bleed the system.

I attached the directions below. Try this and let me know if it takes care of the issue.

Let me know.
