hey, whats up CF
Along side of my 89 XJ
I own a 1997 mercury mountaineer which is my DD and two nights ago
i changed the front brake pads that ive done countless
times before, but this time, when i went to take it for a test
drive the pedal kept going all the way to the floor.
I even had my dad come and check over my work
and he couldent find anything i did wrong

i figured the master cylinder went out
so i went and swapped that too
and i still have the same problem
Can anyone help me??

do the caliper slides still move or are they seized?
caliper siezed?
pads seized in saddle?
did you clean everything up very well?

Nothing was seized up, and everything was pretty clean
i just did the rear pads, and its still the same.
could it have something to do with the ABS?

Possible air in the brake lines? That's the only thing i can think of. Does it still stop with the pedal all the way to the floor?

did you bleed the master and all 4 wheels after?

When i did the front i dident bleed them.
After i changed the master
I bled it and the front wheels
I just changed the rear pads
and im about to bleed all 4 wheels, but its night now
and its 30 degrees outside and im in central Florida
So the brakes are gona have to wait lol

...break fluid does get worn down just like oil and trans fluid...
...worn rotors/drums will cause excessive pedal travel...
...leak in resivor(sp) cap/seal...

also check look for distrubution blocks and under frame connections for leaks

i hope you used bot 3 brake fluid
ive seen people use trans fluid and ruin every seal
