I'm having troubles with the rear "drum Brakes" No matter what I do they heat up. I tried to adjust them (manually) way down like half a pedal and adjuste pedal too (in case there was not enough free play. Still heats up. Someone mentioned the Emergency brake. Any other ideas out there? I had to R & R rear brake rubber line that splits off to both sides and bled them MANY times and seems clear and no bubbles...
