Why do my brakes judder when I stop?
If you’re forced to stop, either shift into neutral or give room in front so you can allow the vehicle to roll slightly while waiting for the light.

What causes the brake pedal to go to the floor?
What typically happens is the master cylinder starts leaking and consequently leaks brake fluid into the booster. This destroys the seals within the booster and you loose pressure. In a slight leak, the booster pressure can be built up when the engine is off, because it’s not pulling vacuum. Once you crank it up, your pedal hits the floor.
What are the symptoms of a bad Brake Control Module?

What happens when you depress the brake pedal?
As the driver depresses the brake pedal, the pedal compresses the piston in the brake cylinder. This compression increases pressure in the brake lines making the brake fluid particles move to the brake caliper. Due to the brake fluid’s high pressure, the brake pads move and squeeze into the brake rotor.
