Second try. First post got eaten. Forum is definitely buggy these days.

I'm working on rear brakes for a '60 Lark VIII. Washed up the backing plates, and found this typical wear:



If those grooves get deep enough, they can interfere with free movement of the brake shoes. First step was to run a bead of MIG weld over the grooves:



Next step was to rough-grind the welds with an angle grinder, and then file them flat with a rotary file in the drill press. I found it easier to use the table-raiser crank to lift the backing plate up into the rotating cutter. End result was nice flat tables again:



In another thread here, mention was made of using Zerks in the threaded holes of the axle housing to pump grease into the rear wheel bearings. That'll get it around the bearings, but not necessarily into them. Here's a pic showing the tried and true method of packing tapered roller bearings, mostly for the benefit of any newbies reading this:



Hand pressure basically squeegees new grease into the open edge of th bearing cage, forcing out any old grease and dirt that may be lodged there. You continue until you have a curl of clean grease coming from every gap between the rollers. Works for front wheel bearings, and throwout bearings, too, although with the latter, you don't see much of anything expelled. But the new grease goes somewhere!
