Could someone please refresh my memory --- Are the rear rotors (2-valve 308) actually press-fit onto the hubs? I don't remember this to be the case, but mine are certainly stuck on there --- perhaps it's just corrosion combined with a close fit tolerance? Anyone else ever observe this?
No they are not--they are held on by 2 12mm bolts---they should be pretty easy to slide off--corrosion is holding them on
if the rotors are really glued to the hub, what worked for me on a 328 was: remove the caliper from the mounting bracket...keep track of the shims! get a couple bolts that will fit in the caliper bracket holes, and are long enough to reach at least to the outside surface of the rotor. Also need nuts and washers for these bolts, and a flat metal plate to protect the rotor. You will damage these bolts, so they need to be throw-away insert bolt in caliper bracket hole, and put on a washer and nut so the nut is between the rotor and the caliper bracket. e.g. as you tighten the bolt, the end will get closer to the rotor slap the metal plate against the rotor and tighten bolts. The end of the bolts will press the rotor away from the hub. Back off the bolts, turn the rotor 90 degrees, and tighten down the bolts again. Repeat and you'll walk the rotor off the hub. since that is probably not too clear, the order of things is: rotor | protective plate | nut | washer | caliper bracket | bolt once you get the rotor slightly separated from the hub, penetrating oil can be shot into the lug holes and it will work it's way between the hub and rotor. The protective metal plate needs to be thick enough spread the load from the bolts. You don't want to dimple the rotor surface. The washer will prevent the nut from gouging the caliper bracket.
