I was planning to buy the oem brake pad kit "1C3-W0046-B0-00" for my 08 wr450. As i see in the fiche, it surely includes two caliper shims, heat insulators and the pads, but i was wondering if it also includes item #6 , the little metal pad support, because mine is missing. does anybody know if it is included in the kit? also, i can see in the fiche only one metal pad support, while in the front brake it takes two, and ind other bikes rears i also saw two supports (or one support and one retainer). It´s clear in the fiche, but it looks strange to mee, because without that second retainer the pads have a little movement in the corresponding end. Really only one is needed? i´m looking at the fiche here: http://www.motosport.com/AR/dirtbike/oem-parts/YAMAHA/2008/WR450F/REAR-BRAKE-CALIPER thank you.
