How do a roller coaster brakes work?

Answer 1

There are several types of Roller coaster brakes, most of them look loosly similar .

The exception is the ratchet brake that goes "Clack Clack as you go up the lift hill.

The next several types look like a metal fin that stick out the side or bottom.

The friction brake rubs a brake onto this fin as the car goes through. Common on old school wooden coasters.

The Linier induction brake, esentially the brake "Fin" goes between a bunch of electro magnets that are computer operated to either speed up or slow down the coaster.

The neatest kind is an Aluminum Fin on the car that runs through a series magnets and through a weird interaction between the Aluminum and Magnet the car slows down. If you vary the strength of an Electro Magnet you can increase or decrease the effect.
