Motorcycle Brake Calipers Motorcycle Front Brake Friction?

Motorcycle front brake friction? - motorcycle brake calipers

I have a1981 Yamaha 650 and I changed the front brake pads. The adjustment is very tight and now it seems to grind the caliper when on the road. I'm slow and can not now at any price. How to relieve pressure on the front brakes? Any help would be appreciated.
