The rear brake on a "new to me" Rev 3 takes a lot of foot pressure to start braking and when it starts to work feels sort of on or off. Is this normal? It feels different from Sherco and Gas Gas but does look to have steel braided lines.

You may find the brake pistons are sticking and needs new pads ?!?!?

You were correct. Upon inspection, I saw that the disk was pushed to one side when operating the brake. After removing the caliper and the pads from the caliper, I found that I could move both pistons by hand. I sprayed with WD40 to clean and then sprayed with brake cleaner to remove the WD40. Upon reassembly it worked well. I did not dissemble the caliper or remove the brake line. I'm surprised that a simple external procedure worked.
