My front brake upgrade has been progressing.... carved out some OVLOV time last Sunday afternoon. As I mentioned earlier, the SKANDIX mounts which adapt the later 850/C70/V70 calipers to the 7/9 strut interfered with the ABS pulse wheel. Remedied with some careful grinding & then primered:

Nothing like summer sunshine to bake on the black enamel paint:

The assembly of the calipers, abutment mounts, and AKEBONO ceramic pads took a bit of fiddling. Also my FCP stainless hoses had to be reclocked after I threaded them into the calipers. Thankfully Volvo did a nice job with a junction block right behind the brake assemblies so the hose and hardline can easily be disassembled & reclocked so the SS hose is not twisted in it's normal position. AKEBONO requires a moly brake lube be applied at the contact points between their pad "ears" and the SKANDIX abutment mount. I also used the Permatex purple "brake quiet" between the piston/caliper and pads. Here is the pass. side assembled:

Well the all important
fit check of wheel to spindle remained. Since the 7/9s came factory with (as small as) 15" wheels, and the stock 280mm rotors, I presumed that the 302's would clear my 16" MSW wheels. The fit check confirmed they CLEAR, but not by a bunch!

A little difficult to make out, but the clearance between the 850/C70/V70 caliper and the ID of the MSW wheel is around 6mm.

I think the next standard disc rotor would be in the 320~325mm OD range.... definitely a NO GO for the 16 inch wheels. My 70 Chevelle Malibu is fitted with C5 brakes all around, and the fronts with 325mm rotors similarly just clear my 17" wheels on that machine.
I'm pleased with the fitment..... you really can't run a bigger rotor setup and the 16" wheels. Those who have followed this thread will note I originally ran 17" Propus wheels, but I've stepped back to the 16" setup for reasons stated earlier.
I think the Zimmermann Sport Coat Z rotors look pretty sweet against those 16" MSWs:

Brake bleeding will be out in the future, but I'm wrapping up the front brake work and hopefully moving into the other areas of my reconstruction (rear axle assy/LSD/fuel pump/rear subframe reinforcements).
