Weird Rear caliper and e-brake question

[twitchy]

Well...my rear calipers were sticking (or one of them anyhow)

and i had the calipers and pads changed on the back of my car. The mechanic told me that until I got a new parking brake, pulling the lever would cause the same caliper(s) to stick / sieze up again. I was in a rush to leave so i didnt really ask why or how. Well i went all week without habitually using the parking brake like I always do. This morning I left to drive 8 hours away with my family and my brother decided to pull my car into the garage for me. He never drives it whatsoever but decided to since there were 6 inches of fresh snow on the driveway and he wanted to spin my tires or something. Hes 17. Anyhow he yanked the parking brake and i found out and lost it. I just paid $500 to have them fixed and now the brakes stick like they did before.

anyone have an idea why this would happen....and why changing the parking brake cable would help this out?

I already lost my car for 3 days this week and now I Have to go back home and take it in again.

I HATE XMAS!
