anytime i drive the car for over 5 minutes and use the brakes the driver side rear caliper wont release so it constantly slows the car down. i already replaced the caliper with a new one, re-bled the system, and blocked off the vacuum to the brake booster to check it but i still cant figure it out. PLZ help!!!

Slide pins. Take them out, clean them up, re-grease them.

You might have to remove the splitter in the rear that splits the hydraulic fluid to both rear calipers, see if that is blocked at all. This is assuming the caliper you are working with is fully functional and you can verify that the slide pins are moving in and out with ease.
