This is for my 2002 Nissan Xterra with the 3.3L supercharged engine.
Brake system was working perfectly fine. I changed the front pads and all of a sudden the pedal is soft, goes all the way to the floor and has to be pumped a few times to get enough pressure to stop the truck. The hydraulics were not opened up. Simple pad replacement.
Since then I have done the following:
bled the system to try to remove air using the 2 person method
bled the system with a vacuum pump
replaced the master cylinder
bled the entire system with a vacuum pump
replaced both front calipers.
bled the system with 2 person method
bled the system with vacuum pump.
The front passanger side is scraping the pads against the rotor enough to keep it clean. The front driver side is so inoperable the rotor remains rusty as if it has been sitting for months even after driving a good distance and using the brakes to stop the truck several times.
There are zero visible leaks in the system and over a period of ~3 months the fluid level has not dropped.
I am at a loss at this point.
what am i missing?
