I think I finally have a line on this one. After said smoke from yesterday on the passenger side, I pulled both sides and poked around. Low and behold, BOTH sides were scorched and melted the dust boot on the calipers.
Which means pushrod after all!! Still don't know why it only pulls right but that's a start. How far to adjust it for the first go? This is the same master and booster that's been on it for years and years... but I think it didn't show up cause I didn't keep my rears adjusted very well. Just a thought.
90% of the time that is the calipers sticking. The pads get thinner and thinner and the pistons move on out to compensate. All that old dirty fluid in the caliper starts creating rust behind the piston. When you put new pads in and take a c-clamp and squeeze the piston back in the caliper bore, it rides right over all that rust and gets stuck.I need to check this out on my 83. I installed a new booster a couple years ago, everything has worked perfectly until I put new pads on the front last weekend.
Now they are both dragging, right side worse than the left. I'm hoping the rod adjustment is my issue. If not I guess my next step is to blow the pistons out of the calipers and polish them.
