I know this is jumping the gun a bit Allan, but when you've finished the rear brake are you going to do an upgrade on the front brake?I've toyed with the idea of machining a new front brake arm, doing away with the pivot so that the arm is fixed directly to the fork leg mountings, then using a suitable caliper with sliding pins. Maybe a floating disc as well, if available. Braking should be stronger and it would get rid of the pesky squeal! 🙂

As Ted said twin upgrade done already with forks, calipers and discs from a cb400n and some calipers that are the sliding type (plus a few other changes to fit the required speedo driveBig difference Best wishes AlLooks great Allan. 👍Sent from my iPhone using Tapatalk
I upgraded the rear brakes on my Cooper S back in the 1970,s no dual brake circuits on them at the time - the rear drums would lock up really easily after my rear wheel cylinder upgrade - ended up fitting an adjustable brake balancer to replace the existing fixed one mounted on the rear subframe. Worked a treat.
Looks good in concept, obviously gives you real look at fine tuning before committing. If you look at the changing alignment of the first link it's going toward a regressive ratio as it gets into travel. If you moved the top right pivot (first joint on white link) to halfway between current location and it's main pivot it will move the linkage to a more progressive ratio. Aesthetically odd at rest as the geometry won't look parallel, but as the brake pressure gets higher in use it will probably give it more feel as well as giving you more cylinder stroke with just one alteration.
