Front disc brakes dragging

I have an issue with my '69 Camaro (front disc, rear drum).

I recently replaced the vacuum booster because the old one developed a vacuum leak.

Since then, I have had 3 occasions, where the front brakes - mainly the right front caliper - are dragging.

I'm guessing either a sticky caliper, or more likely, the master cylinder piston is not returning all the way back.

Where should I start? Thanks.

Added: the brake booster pushrod (between the booster and master cylinder) is not adjustable. The instructions mentioned shimming the master cylinder if the rod is too long. Is there a special shim,or should I just use flat washer? That will cause the master cylinder to not sit flush againest the booster, though.

Re: Front disc brakes dragging

Put a flat washer on each stud between the master and booster and I'll bet your problem is solved.

OR; if you still have the old booster, take the pins out of each booster and compare the length, I'll also bet the new boosters pin is longer than the old booster. Use the old front pin if it's shorter and forget the washers.
