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

Its hard bleeding a master. Air gets stuck in the prop valve. I just crack the back bleeders push the pedal down all the way and have a beer while adding fluid when needed. Then repeat for the fronts.

The whole system will be open so the fluid will go down with gravity.
Did you also "Prime the master before you put it in? as in put in vise to bottom out the valve with a screwdriver to bleed it out before you put it on? If you didnt youll have to take it off cause you will have to get all the air out of the master.
