Have 99 RX 300 2WD. Bought rear rotors and pads from Lexus dealer. Did not purchase the shoes because I did not expect to have both shoes and pads on the back. My problem was when I installed rear rotors. The rotor fit perfect but after putting the tire and 5 lug nuts the wheel is locked. The old rotor is little bit more machined on the back and the new rotor is touching the backplate and it will notmove at all. After removing new rotor and installing old one back it is OK. Went back to dealer and they told me that rotor should fit fine and there were no midification on that model. They said I may have Toyota rotor. Did anyone have this problem?
