Problem: I live on a steep incline, and as of lately when I park: put the car in gear, pull the ebrake all the way up... I get out and the car seems like it wants to roll backwards and does a few inches sometimes. A mechanic (from a $ hungry shop) told me I need new rear calipers and e-brake cable. Just wondering, has anyone else has this issue? Do I really need to replace all this or is there a simpler e-brake adjustment I can do?
