A few real life photo's tell a better tale than those in manuals with shiny bits and the wording " Release bolt A,B,and C", they don't show what you can occasionally come across, or have to solve.
These are from my 2005 free gift car, apologies for the slight image distortion whilst re-sizing.
This is a rear hub showing the ABS ring, you can see the difference between the cleaned section and the rest with the accumulated metallic fragments, at about 10 o'clock you can just see the stripes of the dust on the segments, this and the same on the sensor tip can lead to odd ABS faults.
This is a new and old, can you guess which is which
, front brake plate it is held by three M5 bolts.
This is where the fun starts, the original bolts are mild steel and after living for the past 16 years around 12 inches from every puddle, the head reduces from an 8mm hexagon to a 6mm button, painted white in the photo, so only two ways to remove plate 1) just maul the plate about with a pair of moles or 2) cut the heads off, next to it is a nice stainless one for comparison.
No problem drilling out and re-tapping, which can only be done with the hub off, I like challenges.
Finally, what you may come across if ever you need to change an ABS sensor, as can be seen on this front hub, the nut can be rusted ( the same as with a rear hub but it comes in from behind ) although the sensor body is plastic, rust in the hole can make removing difficult, but if the old one is faulty, no problem
This doesn't answer the problem, but gives an idea of what you can sometimes find when getting stuck into a couple of hours Saturday afternoon job.
