Help on Brakes

i have a 96 Probe GT

anyadvice on changeing the rear brakes?

i have an odd problem, when i turn on my lights my dash lights go out. do you known how i could fix that?

last question where can i get probe parts cheap and reliable and a probe performance site?

1) i cant help woth the brakes b/c i dont trust myself that much.
2) sound like a ground, or wire are touching, might want to play around under your steering wheel.
3) The one and only www.probeaddiction.com (there pretty expensive but got some cool stuff)

thx
