Hey guys can you shed some light on this.
I replaced the front rotors on my 2004 Toyota 4 runner about 5 months ago, because after 3 times to the dealer for whinning breaks when stopping they could not fix the problem. When I did this I used Toyota OEM rotors. When I compressed the pistons in the caliper I loosened the bleeder screw as to not force brake fluid back through the ABS sensor when I compressed the pistons. I put the truck back together and the problem was fixed until the other day, when I took the truck in the other day for an oil change at the dealer. When they were doing the 10,000 point inspection they found that the pistons on one of the calipers was siezed and the boot on the pistons was torn. They fixed the caliper under the warranty, but after getting the truck back I now have shimming of the wheel at speeds when stopping. I took the truck back to the dealer and they are now telling me that the rotors are warped, I knew that that was what the problem was, but they just fixed the caliper, they should fix the problem with the shimming because it wasn't there before and it is now. My question is two fold first of all could the warped rotor be caused by the siezed caliper piston and second the dealer is telling me that the bearings need to be repacked at the same time as changing the rotors, is this true? I didn't have to touch the bearings or the dust cap when I originally changed the rotors. Any help or light on this situation would be greatly appriciated.
THank you
