2001 Hyundai Tiburon, calipers were a dream, rotors required 2 days to remove from the front.
Rust had formed a nice ring around the back of the rotor, capturing it firmly to the hub. Sledge did nothing, oxy torch did nothing, air hammer did nothing... had to use all 3 at once... Should stop a semi after we put the big brake kit on it, uses Hyundai XG300 rotors, calipers, and pads. There's a 1030# difference between the luxury yacht and the tibby. :) Walt On Oct 26, 2011 1:06 AM, "Ed Booher" <edboo...@gmail.com> wrote: > No MB content, unless you count me offhandedly mentioning my W110 and my > W123.
