When I drive my 89 Classic, it drives pretty straight on its own. However, when I brake, the car pulls to the right, so I figured that the caliper. However once the car gets to operating temp, it starts pulling to both the left and right sides. I cant figure out why though. I have been driving the truck for about two years now, and didnt have this problem until recently, when my swivels started leaking. I fixed the leaking, cleaned off both brake dics and pads. Any suggestions as to what it is? Thanks.
