I did the brakes, all four, on my 1990 lumina, and now the left rear is binding. This is ticking me off, I do something on this car that took forever (I didn't know about the tooll you needed to use) and am wondering if there is a way to adjust it myself without a new caliper? (Payday is saturday, don't know if I have enough brakes to drive until then, car is a delivery vehicle) THe other side is fine,. not showing any wear yet, and the fronts are fine. thanks!
