Rear Brake Grease Zerk QD Hub 1967 #818561 08/03/2020 4:55 PM

Reassembling my 67 BSA after 20 years in pieces. Putting together the rear brake, and there is a zerk fitting for the brake cam. Part listed is 28-2080 for fitting into 68-6130.

I've attached a picture - even accounting for the lack of masking from my powder coater (bad story for a different time...) that hole is way too small.

Any ideas as to what might be going on?

Looks like your rear brake plate is the steel type which was phased out sometime around 1965/66 in favour of the alloy type which was used on subsequent bikes.
The earlier steel rear brake plates didn't use a grease zerk and instead relied on a squirt of thick oil, the later alloy brake plate did use a zerk fitting. The oil hole on the steel plate was covered by a type of circlip to protect it from dirt and debris. The circlip is part no 65-5674 "Oil hole clip", see This Link for parts diagram.

I would recommend using a silicone/teflon based high temp brake grease on the brake cam spindle as they are waterproof and much better at lubricating and resistant to drying out.

Grease it properly on assembly and you will be fine.
Put in a zerk and you will be tempted to over grease--getting grease onto the brake linings.
