This doesn't sound right. A breaker passing 10% over its rated current shouldn't be getting hot, and most need more than a 10% overload to trip. If a breaker is getting as hot as you say it is then there is something wrong, either it is passing much more current than you think it is, in which case it should have tripped, or the contacts are poor, dirty, pitted, etc., and there is a high resistance there. Another possibility is bad connections between the breaker and its cables. Apart from any other problems you may have, I think you need to overhaul, or replace this breaker, it sounds like a safety hazard in its present condition.
