First, I'd check to see if the throttle servo fried. that could be holding the brakes on. Then, I'd put WD 40 on the lever and try to work it in to break the lever loose if it has frozen. After that, I'd check for binding in the linkage. or whatever order you want to go in. If you still have your owners manual. It has exploded views of everything. there are exploded views of the MT & TT on Redcat's website as well. I haven't messed with my brake linkage much but I just made sure the throttle and brake worked smooth by just turning on the electronics and just checking to see if it was operating smooth and didn't bind by having the spring etc... move on the linkage.
