I only say air in the system, because the pedal compresses like it does in my other sprite now, and it didn't do that beforehand.
The other sprite is due to leakage past the seals in the master cylinder.
Anyway, it's a 1500lb car, so it's not hard to make it stop. I've always got the e-brake, which is working well. I can lock the front tires on the car, and when I'm yanking the ebrake while using the foot brake, the car stops nice and level. I might need to buy new rear cylinders. I'm pretty sure one of the pistons (or more) is frozen right now.
