Hi Klaus.
I don't have a FWD Volvo yet (still have a fleet of 240s, but I know I'll someday have to change over), so I don't know what the assembly looks like, but I've been reading the FWD forums regularly for educational purposes so I'll be ready when I get my first FWD. Which brings me to a question:
I read your remark, "...The holding pin ... holds the rotor in place until the torque of the lug nuts takes over. Don't want the rotor falling off when you are changing the tire in the dark...."
This has me wondering. I thought that FWD's rear brakes were very much like the 240's rears (i.e., not of the "floating caliper" type) in that the calipers were firmly bolted in place. So if the calipers are in place, won't that hold the rotor so that it doesn't fall off when the wheels are removed? On the 240s, there is also a small (10mm) holding bolt (later, a pin), but these can be removed if you have (e.g., older winter) wheels without the provision for the pin -- and the rotor won't fall off when you change your snow tires.
So I can't imagine how a rotor could fall off if the caliper is in place, so can you explain this?
Thanks.
