B Brake problem

[Dave Houser <mgs4dave@warwick.net>]

An Open Tech Question,
Here's the problem. 64 MGB going fine until front brake noise, disc 
smell and pull to right tell me I have a problem. Check right wheel, 
slightly warm to touch, motor home and forget about it. Next time out 
driving for about an hour, you guessed it, same problem returns. Car 
cools, no problem going home. So what do I check? Bearings? Pads? All 
possible tips appreciated.
