to test the sensor you need an o-scope so just replace it if there is any doubt. to fix the dragging you need to rebuild your calipers and prolly do a full brake job. you can get rebuild o-ring kits from mazdatrix for something like 13 dollars a caliper....

when he said it was your brake lines, did he mean the 6 or so inches of rubber hose or the hard lines that route back to your engine bay? if it's the rubber ones then yes the ss lines will fix the problem because you are replacing what has failed....make sense?

yea what he said.
but to add a little bit too it. if putting the SS lines on doesn't fix it then it could get pricey. most of the time replacing the rubber lines (most people replace them with the braided lines) should fix the problem as they deteriorate internally and block themselves up.
you could try opening all the bleeders and doing a complete system drain of brake fluid too might help you out, you could do it when you put on the braided line.

ok well yeah he meant the 6 or so inches. and i ordered corksport single rotor ss lines early this morning so that should fix the problem.
on one hand, it makes sense that the ss lines will fix the problem because this car's been sitting for a decade before i came along and bought it (a few coolant hoses were dried up and so are the tires). on the other hand, ALL four brake lines failing? of course, some brakes are worse than others but they're all dragging.

Well, it is possible for all 4 brake lines to be collapsed/pinched, but with the car sitting out for 10 years, I'd still check and make sure the pistons in the calipers aren't seized. If you have any doubts, just replace everything. I recently put new calipers, rotors, and pads on my GXL and truth be told, it wasn't very expensive. I got rebuilt front Bendix calipers for $38 apiece (lifetime warranty), $33 each for front Bendix rotors, and $35 for front Bendix pads. Rear calipers tend to be a lot more expensive, I think I paid $90 for my left rear when the parking brake seal blew. I got everything from Advanced Auto, because around here their service and prices are very good.
As far as the Oxygen Sensor issue, I also just replaced mine on the same car, and I think I paid $18 for a universal Bosch one from Advanced Auto, it definitely improved my mpg, considering that the one that was on there before wasn't hooked up - the wire was melted through. I get about 21mpg in mostly stop-and-go traffic, with some highway speeds in between. My car is an 86 GXL with a full RB exhaust, cone filter, and 255 wide tires in the back, so it's not too bad.
