I just did a full rotor and pad job on the car yesterday. I guess the Z17 brake kit (rotor and pads) did their job. It could of been a combination of issues that caused the parts to prematurely wear incorrectly. I noticed some of the guide pins were stiff (cleaned up and used the correct lube) and both front piston gaskets were damaged (probably from the previous owner or shop that last did the brake job). With Hawaii stop and go traffic within 10 miles, brakes will get beat up around here. I replaced them with Autozone rotors and Gold pads so at least I could get some "warranty replacements" if they do fail within a year. Going to be looking into front caliper replacements because there's no telling how bad those gaskets were torn nor the condition of the pistons inner sleeve. Parts are not easy to come by out here and 9/10 times have to pay an exorbitant amount of money to ship a simple part out here. Amazon doesn't even ship a lot of things out either compared to the mainland so that option is very limited as well.
Here's some photos of the uneven pad wear, cracks and pitting on the Z17 rotors and pads. Hopefully by doing the brake job myself will produce a better outcome compared to what was done before. Also, I don't think the geomet coatings lasted as long as they should have, even living here under island conditions.
