Anyone who paints brake calipers and rotors might be interested in knowing that Plasti Dip appears to work well even on hot brake discs. So far, Plasti Dip is still looking good on the right side front brake caliper and disc, which I painted at least 500-1000 miles ago. This is surprising because Plasti Dip is only rated to 200 degrees. I originally painted the calipers and discs with PlastiKote 500-degree caliper paint but it simply does not stay on discs. It does well on calipers, but not on discs even though its temperature rating is much higher than Plasti Dip. PlastiKote will stay on for a while but then flake and/or burn off, which exposes the disc to rusting. Plasti Dip is rubberized and flexible, which I suspect is why it hasn't flaked off. Just tonight I took a good look at the caliper and disc and sure enough Plasti Dip is still looking good with no visible signs of rust even on the edge of the disc. I thought that by now Plasti Dip would have burned off, but it not only is still there, it basically looks as good as when I first sprayed it on. The real test will be during hot summer months when discs have less cooling ability due to hot weather.
I thought I had JE5 brake discs but after putting on one of the Duralast disc I bought from AutoZone, I was concerned that I bought the wrong size. The Duralast was obviously bigger than what was on the car. I'm thinking, it looks like the caliper bracket may not fit. So, I put the disc on--and thought--WOW! That is one pretty big disc! But, what do you know, the bracket fit with about 1/16 to 1/8-inch to spare. Apparently, the discs that were on were not the right ones, which explains why my brakes are gouged/grooved on the inside. The rotors I replaced didn't have enough surface area to accommodate the larger JE5 brakes. I suspected something wasn't right and now the new discs confirm that I was driving around with undersized discs. What else, since the Duralast discs are for JE5 brakes, have more surface area, and fit. My guess--and most logical answer--is that the original factory discs were replaced before I bought the car with the wrong ones. Now I have to replace the brakes a soon as possible, so I don't damage the discs. I also have Duralast on the rear. So far, so good. They are holding up well after at least 6 months.
