Hi, recently crashed my car into a tree! at the time i thought sumthin was wedged under the brake pedal as it wouldnt depress properly. Having looked at the car since the brake pedal only moved about an inch. Thought it might have been damaged in the crash as the bulkhead ended up ina bad way, however after the brakes were all disconnected to remove the bulkhead the pedal started to move properly again!! any ideas as to what the problem could hav been??
