Hi paul welcome back. Pedel problem sounds like a seal in the master cylinder has given up. Happens when they are left sitting for a while. A little moisture gets in around the rubber boot on the end of the cylinder and causes a little rust. Once the brake pedel is operated it grinds away the edge of the seal alowing the fluid to bypass it. A good clean up and a seal kit should have it sweet. Looking forward to seeing some pix of dolly on the road this summer (just going into winter here)
I just need a good rootes...
