90+ Brake Plates

[giz.neal]

Gentlemen,

2 queries:

The small grease nipples located in the brake plate for the 'cam operating' shaft specific to the Plus (as opposed to the ones in the end of the shaft for the Mk series, Plate No 27, Pt No SA.1496), what size are they?

It appears that the 'cam operating' shafts for the plus are of larger diameter to the Mk item, is this correct for the Plus?

Yours

Happy New Year,Steve.I just looked at my dismantled Plus brake plates and the grease nipple on the rear item measures 0.185inch(3/16th inch) so maybe BSF OR 2BA?Regarding the 'cam-operating shafts',both of my Plus items,front and rear,measure 0.562inch (9/16 inch),and my Mark ones are both 0.496 inch (half inch).Hope you are keeping well these days? Best wishes,Ken Playfoot.

Ken,

All is well. Yes your measurements confirm my findings, thanks! Hope you are well

I'm pretty sure the small grease nipples are 3/16" BSW as opposed to BA.They are found on eBay under Bicycle parts;used I think around bottom bracket lugs of "racers".I spotted some this week.
