the way i started was brakeless, it sounds stupid, but instead of rocking onto you're back wheel using the brake, try rocking and getting you're wheel up with pressure on the pedals.
when you get to taht point hit the pedals and hop ( not to hard ) when you land the wheel may roll out underneath you so it would be good to start on grass to save broken a broken ass.
Anyway after you manage the hop part try and land with you're brake on then go for another hop, after a while you should be able to get 1-3 hops but not keep going, its all about getting you're own personal point of balence, and when you do you will just get better and better. I hope this helped, Zac
