What is the Sachs part number for the friction disc? I haven't been able to find one from any of the suppliers I have tried.... I used to be able to get the complete Sachs kit, part # 271265, but can't get it anymore.
About your findings performing your power-brake test -- did you have someone watching both rear wheels? Volvos use a very heavy brake bias towards the front and a dual-circuit hydraulic system where each rear break is on a separate circuit, which depending on the condition of everything can lead to a little more application force on one wheel than on the other -- plus you have the open differential which, in my cars at least, always seems to have a noticeable bias towards the right side rear wheel. I wonder if the scraping sound you heard was one rear wheel still spinning?
