you can fix em....if you got a some metric allen wrenches, some screw drivers and a couple other misc tools, and some patience you can fix anything and everything on your truggy...thats why we are here...to help you....we are your online bro's that want to make your rc hobby enjoyable.....

one thing you can do is order another set of brakes and double them up...but your truggy should stop just fine stock if set up properly....the front knod on the rod attached to the throttle servo horn is one adjustment...also on both sides of the center differential you will see your brakes....the 2 screws holding the chrome piece is another...I would get my handy dandy (2.5 mm I think) allen wrench and turn both sets of screw IN 1 turn...try your brakes..if not satisfied turn some more...if they grab too good loosen them up a bit
