Ben,
I'd take bearing out just to lube and clean. Really simple, just take note of the way they are oriented when they come out. New rotors are fairly cheap or just get them turned. If you go that far make sure you test condition of front end, wishbones, etc. Take a look in the back of the MOSS Catalog on detecting wear and tear on Sridget Front ends. Also you need to carefully inspect the wishbones for cracking. Lack of grease causes these parts to lock up and end result is cracked wishbones underneath all of the grease. Lots of PB Blaster on Bleeder screws multipole times before you try to do anything. Leard there is a treick using I believe a 1/8" drill bit inserted into bleeder screw before you attempt to loosen. 1/8" drill fits into bleeder and prevents bleeder from collapsing or breaking off. Sometimes heat helps as well. Be sure to replace both front and rear hoses. Limit is 10 years max, Spridget BMC Manual calls for 2 years or 24k miles. These hoses collapse internally and there are no apparent signs of collapse. Had issues with Front Brakes on my '68 pulling and not braking properly. Discovered issues with front hoses that were 12 y.o. and < 10k miles. Back hose collapse also affects rear brakes, found that first time around, no fluid getting to rear wheel cylinders due to collapsed hose. Slow and steady and your '69 wil lbe back on hte road.
BTW - Nice Wheels!!!
