Cobra just did the walk of shame
I just went down and picked it up from the shop and trailered it home. I had to have it explained to me several times and then look at the assembly a bunch. The rotor bolts on to the back of a plate (kind of like a two piece rotor). The plate bolts on to the back (inner side) of the bub with the bolt heads being on the back side and the pins which ultimately hold the wheels in place capturing the bolts on the front (outer) side of the hub. The hub is held on to the upright by a nut on the back (inner) side of the up right. The nut sets the preload and I have been told draws the hub over a splined shaft. The up right has to be disconnected from the upper and lower control arms and the tie rod arm. The nut has to be removed and the bearings and hub have to be pressed off of the upright. If you don't press it off you can damage / flatten the bearings. Once you press the hub / bearing / plate and rotor off, you now have access to the fasteners and can machine the rotor if necessary. My mechanic also showed me that there is some slop / play in the hub right now, so we need to check to see if we can eliminate that with some more pre-load or if we need to change the bearings or if it is just a design problem. The original 4000 series had a relatively standard hub with a rotor that just slipped off once you removed the brake caliper. I am going to play with it some more tommorrow. I still wish some one could explain why the hub / rotor assembly was redesigned for the 4700 series from what the 3000 and 4000 series has.
