Not a Ford but i didn't know where to post....


I can press the Brake pedal all the way to the firewall and i gradually stop, but not right away. What could cause this problem? Air in the lines, bad seal? leaking lines, leaking calipers?

I replaced the master cylinder just recently.


The Truck is a Nissan Pathfinder 1992 Let me know if u can help.

Thanks
Steve
