90+ front brakes
« on: 15 Aug 2015 at 22:32 »
Afriend of mine has luckily found a 90+ to restore. Most parts are there, however the wheels are missing.
Does anyone have a front wheel or brake they would be willing to part with?
Has anyone ever produced patterns and castings for these brakes?
Thanks,
Roger (UK)

Roger,

I needed a mudguard stay carrier plate for the RH side and CNC machined a small batch from plate. No sooner than I did that (and as is often the way), and someone in the UK started offering the castings! But I have not heard of the rest of the brake being reproduced.

I'm sure I've seen John Carrick advertising Plus front brake plate castings over the years in the NCR - could be worth a try

Sorry, that should be John Caddick

Thanks for this,
I've now found a front wheel brake backplate and brake shoes, but still need a brake drum, wheel centre (were they separate?) and the mudguard stay backplate - I will see if i can talk to John Caddick on that one.
Regarding the rear wheel, am I correct in assuming it is the same as a mark, but with the sprocket bolted on? Would it be possible to modify a mark wheel by turning off the existing built in sprocket?
Thanks for your help
Roger

Roger,
           Both the front and rear hubs were the same as Mark hubs - just the brake drums were different. The front drum was, of course, larger in diameter. The rear drum was the same as a Mark, but had the bolt-on sprocket. The rear brakeplate was slightly 'beefier', and whilst looking like a mark unit, had an operating cam with a slightly larger shaft, and the boss on the brakeplate was drilled and tapped from the rear for a grease nipple (the Mark had the nipple in the end of the cam spindle). If you come across a rear drum, make sure it is for a 'Plus' - the 'Comp' had the same setup but the sprocket was offset more to the outside.
  Regards,
                 Eddie.

Thanks Eddie,
The puzzle is becoming gradually clearer! I'll now look for Mark front and rear hubs.
