How a Brake Booster and Master Cylinder Work
The Mazda is being difficult, which is foxing dutiful daughter. It won't start and when you try if acts squirrelly. Being a modern car, you need to push the brake pedal before you push the start button, so according to delightful daughter it's a 'push-start' car, which foxxed me when she said it. To me, push-start means a couple of guys pushing a car to get it rolling and then popping the clutch to start the engine. This used to be common knowledge. I wonder if anyone under the age of 30 has ever done it.

Anyway, back to the Mazda. Under normal circumstances, when you push on the brake pedal prior to trying to start the car, it moves, not much, but you can feel it move a bit. But now, devious daughter tells me, it doesn't. Being an independent sort, she did some Googling before she called me, and now she wants to know how power brakes work. I explained it as best I could, but then I thought a video might help, so I went looking and found this one and it's pretty great. There are some subtle funnies mixed in with explanation, and it's all technical all the time, so I enjoyed it.
