2002 saab 9-3front brake caliper
 

driving home a couple days ago I started to hear a strong metal to metal rubbing noise in the left front wheel. i got the car up and spun the wheel..quiet...pulled the wheel off turned the rotor ..quiet. conclusion as i observed the caliper was still in full extension..and believe it has seized.. the other side..right front as I am coming to a stop...i hear a metal piece hit the underside of the car..the brake caliper came off! and the brake fell into the rim..i drove the rest of the way home (a mile) using my emergency brake...

did one cause the other from brake line pressure? that is a serious amount of pressure to pop a brake screw. I can work on the brakes but need to know where to start on this.

thx

The whole caliper came off? That would have nothing to do with brake pressure, but rather bolts coming loose. Unless a piece of the bracket broke off.

bolts did come off did not strip amazingly ..this happened on the passenger side.

the rubbing metal sound came from the driver side...it looks like the caliper was really out there ..a lot more than usual for relatively new brake pads.

i was able to compress it and pull the brakes off is there a way to seems like if it were to seize it wouldn't compress .

in the back brakes i have a rattling metal noise ...with all the stupidstuff i deal with on this car the engine thankfully is strong as ever.
