Cadillac Repair/1981 Eldorado brakes and climate control


Working on a 1981 Eldorado and just replaced the brakes rotors and pads and they worked great let the car sit for a day and now they go to the floor and have to be pumped.  Checked the power booster and it is not making any noise as don't believe it is leaking and when you disconnect it there is the wising sound of pressure.  Trying to figure out what else could be wrong doesn't seem to be leaking any fluid or anything.  Do you have any ideas what else I could check to make them work properly.  
Second also am looking at the heater, the antifreeze was low so filled it back up but it is stuck at 90 degrees and will not go down or up for the temperature and there is no noise or fan/blower working.  Checked the fuses and they seem fine so what would cause the temperature to be stuck and the blower to not kick on in any setting.  Cool or heat?  Any help would be greatly appreciated.


Unfortunately, your questions require quite extensive answers and will need to be presented separately.
As for the brakes, there again are many answers, but I need to know what brake assist it has, vacuum or hydro boost? Vacuum located behind master and hydro boost not.

Alarm system questions cannot be answered on this forum. These systems are not what I can answer. Without being physically at the vehicle and not knowing what kind of electrical service has been done on the vehicle, there is no possible way to give an accurate answer over the internet. My expertise is in Ignition/key based anti-theft systems. These issues include GM VATS (resistor chip in key blade) PASSLOCK (MRD)-ignition lock rotation based, no special ignition key and the PKIII Transponder (computer chip in key) systems. These systems are not alarm based and are integral with the starting of the engine. This is why I cannot diagnose alarm problems without physically looking at the vehicle: Alarm systems are a completely different annimal than ignition key/lock based anti-theft system. Many alarm questions come from vehicles 10 years old, and since older, many hands that had been involved over the years.I am an expert in all GM factory (ignition/key based)systems. Alarm system questions pose to many situations beyond my knowledge as to what has been done to the vehicle over the years. Some guy may have actually wired the stereo into the alarm system. Who knows? Over my past 30 years in vehicle wiring repair, I have seen unbelievable wiring disaters done by guys that consider themselves "mechanics." I have seen stereos and alarms intalled using surgical tape. I have seen modules burn up, un-fused circuits, wiring jambed between the doors and even lamp cord used for a starter kill. To answer alarm questions over the internet without examining the vehicle is like asking; What does it take to remove a dent?
