While not an expert on the L4701, I looked at the parts diagram on Messicks
and, like my L35, the brake pedals are mounted to a common axle that actuates the left and right rear brakes.
When I rebuilt my L35, there was a ton of rust and crud on every joint, including the axle to brake pedals. A mess. Yep you're correct - no grease fitting. Not having the condition of your machine, you might try penetrating oil on every joint from the brake axle to the rear brakes, and large amounts of brake actuation to get things loosened up.
Since I was tearing the machine down anyway, I removed the console and cleaned and lubed everything in that area.
