Maybe the brush you are using is hurting. What kind of brush do you use? Maybe you should try a Christensen brush.
Although some consider them a bit expensive, I think they are totally worth it! I bought a Christensen brush for my Sassy and she loves getting brushed! See them here:
Pin Brushes
Maybe you could make some small treats (Cheerios?) part of the brushing session and this would distract him and make him look forward to being brushed. I always brush Sassy on my bed and all I have to say is "Let's go get brushed" and she zooms right in there.
Hope you can work it out. Being bitten is definitely a problem!
