I just want to warn everyone about a guy named Jonathan Ross Gibbs out of Slisbee TX who uses the business name Engineered Coating . He has a website and sells on eBay. This business offers powdercoating and refinishing of brake calipers and other miscellaneous small items. I bought a pair of supposedly fully disassembled, powder coated, and totally rebuilt rear calipers with new brake pads for my 2003 Cobra from him. He told me I would have the calipers in less than one week. I paid this guy, $415.99, less $200 eventually, for the return of my cores on Aug 31st, 2012 and did not receive the items till Sept 28, 2012. When I received the parts I was shocked to find that the calipers were not fully disassembled and rebuilt as advertised (was obvious because the seal for the built-in parking brake shaft, the big spring, and parking brake shaft was powder coated red), the brake pads were for a GT not a Cobra, the slider pins were mixed with coarse and fine threads, and the caliper brackets were scratched. When I called him I had to explain the difference between GT and Cobra pads and he said he had no idea there was a difference. He said that he would send the correct set of pads and another caliper bracket overnight to me because he already delayed my project. After a week goes by and no parts, I tried to get in touch with him numerous times and no response. The only way I was able to get a response from him was to file a complaint with PayPal. In his response he admitted that everything I claimed was true but that it was too expensive to overnight the parts. After 2 weeks go by I finally get the parts owed to me (after I already bought pads from the local Ford dealer) and finally get to install them on my car, now this is in November, only to find that both calipers leaked from the parking brake seal as well as the piston boots. Now I spend extra money to buy a rebuild kits for both calipers and rebuilt both calipers myself. One caliper I was able to fix but the other turned out to have a damaged piston in it. I texted him explaining the problem as well as sent pictures of the leaks and he said he would send another caliper. 3 weeks go by and no parts and no response from him after numerous calls and text messages. I finally ended up buying two calipers from RockAuto.com that come fully rebuilt with all brand new hardware as well as powdercoated for $160, less $45 for my cores, shipped to my door with a 90 day warranty. That is $100 less (after refund for the cores) than from this guy and comes with a guarantee from a reputable company. I just want to make sure that nobody else goes through what I have with this guy.
