Is there a real need for it? Most brake questions are answered in the general car chat forum. I suppose if there was more feedback from members actually wanting this then Waynne would have done so a long time ago. Brakes for me seem to be one of those areas where the new members to car modifying forget about it. They think power, fancy wheels and tyres but forget about how they will actually stop.
If you guys think that there is a good need for it and there will be lots of discussions in there then I'll happily add a forum. IMO it doesn't come up enough, but it really should.
