I noticed my rear near side brake was overheating, so suspected the caliper was sticking. I stripped the brake, cleaned all rust off, cleaned and lubed the slides, retracted the piston, which seems to move ok now. The problem is now both sides seem to be making scraping noises off and on, which usually goes away after reversing for a few feet. I can't see rust or obstructions on the back plate where the noises seem to be coming from. I haven't had time to take the disks off to look at the drum brake side of things yet (12 hour night shifts), but could the noise be coming from the drum brakes? I have read that the shoes can be problematic on these cars. It is a 2001 V70, age of shoes unknown.
It's very likely the drums. The shoes will almost certainly be original, since the drums are only used as a parking brake - so the shoes, in theory, should never wear out.
The rear brakes on my 2007 (not latest shape - so probably same as 2001) V70 make graunching noises if I apply the handbrake whilst still moving
- but as far as I know they don't overheat. At the 3-year service, the Volvo dealer took them all apart but couldn't find anything obviously wrong - and they were no better afterwards!

I pulled the rear brakes apart today. Near side was OK but shoes very worn. Offside was a mess. Both shoe retaining springs had worked loose and were rattling around the drum gouging into the shoe braking material etc. Shoes and springs a total mess. Thankfully no other damage, all I need to do is replace shoes and spring sets. I have the spring set, but am still waiting for the shoes, which should arrive tomorrow. If they don't, I have to drive to and from work with no handbrake for four days and go to a funeral before I can get time to replace them.

Yes you can. Wheel off, caliper bolts undone 7mm Alan key . Caliper hung out of way. Caliper holder bolts off, 13mm bolts. Disk/drum retaining bolt 10mm. Pull off drum.
Recently, I noticed the handbrake needed adjusting to bring it back to 5 clicks. Then I heard little bangs and grinding from the back brakes, then I noticed the near side caliper seemed to be seized judging by the temperature of the wheel (steel). I decided to have a look, as I have done the same with my older Volvos, a 240, and three 740s. I was expecting to see something like delaminated shoe friction material, but found that the shoes were still in one piece, but very worn. The problem was that the holding springs in the middle of the shoes were missing, or rather displaced. They were rattling around the drum, taking gouges out of shoe linings here and there, they were badly deformed due to the hammering they had taken. This meant that the whole assembly was floating about in the drums. They still managed to hold the car and a caravan on a hill though, but if I had known the state of them sooner there is no way I'd be using the car handbrake for that, or indeed towing with the car. I replaced the shoes and the springs, £23.00 for the shoes and £8.00 for the spring set. Feels much better now, but to get the shoes in I had to shave a bit off the shoes where they fit onto the expander. I had already sanded down the lips on the drum. The old shoes were Ferodo and the new shoes are Bendix.
Does it make the noise when driving along, or only when applying the handbrake (parking brake, if on the west side of the Pond)? The drum and shoes are only used by the handbrake. When my 2007 V70 (same body shape as yours) was just under 3 years old, it started making graunching noises from the brake drums if the handbrake was applied before coming to a complete stop - and sometimes when pulling away after releasing it. I had the dealer strip it down and check it while still under warranty, but he couldn't find anything obviously wrong, and it continued to make the noises when re-assembled! However, it gradually got better on its own. The car is now five and a half years old, and no longer seems to make these noises. Perhaps yours will get better, too!
