I found a really great Toyota mechanic here in my area. I brought him my '00 T4R to get the wobbly brakes fixed. I told him that I knew this model had a reputation for warping rotors. He agreed and said that its a problem on other models from that period, too. When I asked about a more lasting fix, he explained that the problem is not in the design, but the metallurgy. He said that over time he realized that Chinese rotors warped, but Bosch rotors did not; owing to superior quality steel. He said that he only uses Bosch rotors now and that he's not had one come back warped yet. I don't know if this is BS, but so far my 4Runner is steering and braking like its brand new. I guess parts are not always the same...
