Update: The modification on the Tam brakes didn't work. One went ok but using a hacksaw is too clumsy so it didn't cut straight on the 2nd one. Anyway, I thought I would share this find. I have a set ordered. They use a 25mm brake pad which is what the Tams use. The axle hole is way big but can be shimmed down. Not a bad price either.
Also, I will be posting all the parts from my previous gear tests for sale later today. Take a look if interested. (tam restracts, springair mains etc)
