help with fitting V70R rear rotors over e-brake shoes

This is what my roller cam mechanism looks like, taken from another thread on this topic here at MVS:

Confused me for a second as the last picture of for possibly a P80 V70XC as the back plate is deeper dished than that of the V70R (one year rear brakes most parts un-obtainable). Your back plates look past there best as there are whole chunks missing. This is another of Volvos great ideas where you have to pull the center hub to be able to fit the back plate or remove the old one without cutting. I know some guys just cut a slit through them and that allows them to bend them enough to get over the hub without removing it.

Above is one of the pair I have stashed away for the future. They probably cost me close to $120 US each to have a specialist parts yard remove them for me without cutting them and then having them powder coated. These were very hard to find in good condition. Found them at Chapman Motors on Vancouver Island (West coast Canada) where they use very little if any salt on the roads.

Good luck, and glad you found the issue.

Wasn't sure about your comment on how to adjust the roller, I'm guessing you mean the adjuster wheel.

If you rotate the lug nut holes you can usually see the adjuster through the hole. I use a long flat blade screw driver to turn it one tooth at a time. It rubs against the little spring on the shoes to stop it moving by itself.

I normally tension it until the hub won't move and then back it off 3-4 clicks. Then take up at the brake lever until it has a maximum of 5 clicks to locked hard on.

There is no hole in these rotors to adjust that cam, not in the new and not in those removed. I think the intent is to adjust them from the back/underside, there is some little access. Not entirely sure on that last part, but definitely no holes in the rotor unless one were to count the actual lug hole (sorry, edit for mistake).

Sounds like you figured it out so this is probably water under the bridge at this point. But since you asked for photos of the expander thingy before, I thought I would add a few. I just did this job on my XC a few days ago.

This guy needs to be well lubricated. The old ones were completely seized which left the parking brake non functional.

I had a hard time putting the springs on and everything fell apart right when I thought I got it.
So I came up with this little trick which worked like a charm.

All put together with springs.

Thank you, Dirk. Yes, my cable "adjuster" mechanism was rusty, but not seized. I did lube it for good measur.

After seeing your photos in addition to looking at every photo of parkign brakes on Volvo across the internet for the past 24 hours... I think my parts are in correct. The previous owner or his mechanic must have installed incorrect pads and/or the adjuster, as there was simply no way to fit the shoes into the rotor. My reason for believing that they are not correct is that I could not, no matter how I adjusted everything, get those two ends of the shoes to meet at the steel nub, as in your 3rd photograph.

Wrong parts suck.

I found my first set of rear brake shoes on my 1999 were too big and had to buy by VIN number
