Odd brake issue

[meanletters]

I have a '72 Coupe and after about 3 miles of driving the brakes 'apply' themselves and I slowly come to a halt. I let the car cool for 10 minutes or so and that usually frees up the brakes again enough to get me back home. Has anyone else seen this issue? Know where to start troubleshooting? this is my first Honda 600 so I have a lot to learn!!! I love driving my 600 but I'd love it more if it could make it more than around the block.
Your thoughts?

Ps-any one know of a place that will make 600 seat covers?

I had one once that  did that and drove me crazy trying to figure it out. It kept building pressure in front calipers, I would break open bleeders and it release the pressure. I had changed both master cyls and booster with no change. Tried every piece with no change.One last part was the vacuum check valve in the vacuum line. It was full of corrosion.  I replaced it and It fixed it. To this day I don't understand why,but it was fixed.  Usually the problem is on most cars is no freeplay at the pedal. Good luck on it!
