just order brakes for a 2000 2wd tundra with the v6 motor... that should get you the smaller brakes if the calipers you get have "13WL" cast into them then they are the wrong ones, you will need to tell the parts house to order the "other ones"....
No, the brand you're thinking is Wearever. I haven't heard bad things about them. I got the Wagner blanks from Advance since I can exchange them any time in case they ever end up warping.
Funny thing: just took it to the mechanic to take a look and on the way there was no shaking or vibrations on the highway on 55 and 60. I didnt do 70 today, but some how its just like it was before. Maybe I should give it some time, wait till it starts shaking again.
