I agree with the others, try another copper washer for starters before doing anything else. This is the easiest fix to try. The color of the calipers should be black. I believe 1613 semi flat Krylon will work just fine. If you want to replace the calipers Napa carries rebuilts that are identical to the originals. They have the Delco stamping on them. Another thing you may want to consider or check is the fluid level in the master cylinder. You DO NOT want to top it off using the silicone fluid. You want to leave the fluid level approx. a half an inch down from the top of the master reservoir. Silicone fluid will expand in the closed system. Hope this helps ya...
