Nothing is more terrifying than cruising down the street to the fairgrounds when some idiot pulls out in front of you and you have to jump on the binders. Making a panic stop can be difficult when you are trying to stop 800 throbbing horsepower with a set of 9-inch rotors and single-piston calipers. You might even wonder if it will stop as you mash the brake pedal. When it comes to street rods with big motors, one braking concern is vacuum pressure. Is there enough? Many high-performance camshafts add power to the motor but produce low vacuum levels. This is something to consider when selecting your engine components. Of course, if the motor fails, you will have no vacuum, so stopping will be a real problem.
