The OEM caliper is every bit as good as the FZS1000 one which many replace it with (myself included) , but it has a design flaw in that the small drain holes at the bottom get blocked with crud and water/salt will rest within the caliper and corrode it and pads on poorly maintained bikes. The FZS1000 does not have this issue as the bottom of the caliper is completely open like the top.
To sort the OEMÂ caliper on the FZS600 and 400 properly this kit from Powerhouse is what you need as it includes the inner caliper seals which allows you split the caliper to check out the caliper completely. Yamaha do not supply the small inner seal.
