You've gotten the advice I would give. If you work up slowly enough, a dog will let you do just about anything to them if they know they are getting a treat or good long play session afterward. Just do a tiny bit of brushing several times each day and reward him for going through it - even if it's just a few seconds.
In time, he will allow a full brushing session but it could take months if he's terribly fearful. That's okay - just imagine something you are very fearful of and shakes you to your core being done to you - such as touching you with a snake or spider - and you'll understand and go at a slow, slow pace a little each session and then always give the reward. Also, always allow him to go outside to potty and de-stress, run off tension afterward.
