My braking system is not working correctly.

When I got the coach beginning of February, all was well.

a couple-three weeks ago, however, I got the brake warning light,
accompanied by the pedal doing nothing for the first half of its
travel. I'm still able to bring the coach to a stop, but I have to
really push hard if it's going to be a quick one. for a while, every
other pedal push would get full braking, and the light would go back
out. then, it was every third, then every fourth.

Now, it's on much of the time. I can reliably shut the light off, and
get normal pedal feel, but only if the parking brake is engaged.
without the parking brake, it's once in awhile. Judging by
temperatures and sound, its the rear brakes that I've lost. the front
reservoir is about half full.

Now I went and bought a bottle of DOT3 fluid at O'reilly, but it
occurred to me that I don't know what the correct fluid to use is,
aside from the old GM part number, 5464831.

Any advice? i've already looked over Gene's brakes pages, and aside
from the advice that I install a vacuum pump, and which master
cylinder is OEM equivalent, nothing there seems terribly useful to my
situation.
