![]() ![]() A fluid inlet allows high pressure brake fluid to flow inside, creating a pressure inside the cylinder pushing the piston and the brake pads attached to it, eventually creating a high compression force pressing the brake pads against the rotor resulting in decreasing its speed or to stop the rotor. In the Baja vehicle a fixed type brake caliper is used. Basically there are two types of calipers floating type and fixed type. ![]() It is an assembly consisting of brake pads and pistons. Eventually creating high pressure inside the calipers leading to compression of brake pads with very high force. As the pedal is pressed, the plunger connected to the pedal moves in opposing the piston return springs force to push the piston inside, creating a pressure in the fluid by pressing the fluid present inside the brake line. The other chamber of the master cylinder is the compression chamber, responsible for retaining pressure in the brake lines even when the brakes are released. It is a device comprising of two chambers, one chamber is the reservoir containing Brake fluid, which is the working fluid in the braking system and is responsible for compensating any fluid curtail in the brake lines or due to leakage, though rubber seals are used for preventing leakages. The braking system consists of following components: The aim of the braking system is to provide a reliable and easy to operate system capable of locking the wheels, and provide continuous control over vehicles speed in all terrain. The braking assembly and components are restricted with space complication of a compact BAJA vehicle, where all the components and assembly needs to be accommodated in a sound and functional manner without restraining any other component or the driver or any of its motion.Ī passel of calculations hence need to be done in order to achieve the goal to lock the tires within the given distance keeping all the constraints in account. The force of compression on the brake pads are generated with the help of fluid pressure generated as a result of the force from the foot brake pedal. to lock the tire within a specified distance. The frictional force produced by the pads on the disc all together should be enough to counter the rotation of the disc and bring it to stationary i.e. The braking system works on the principle of energy conservation converting the kinetic energy of the rotating disk in to heat energy, produced due to friction force between the pads and the disk. Hence, enabling the driver to have a good control over the vehicles dynamics. It enables the driver to press the pedal and control speed by decelerating the vehicle. The braking system is an essential device of a vehicle used to retard the vehicles speed and provide control over its motion. This document gives a brief introduction to braking system and provides a calculation methodology to calculate and determine the rightful braking calipers for a BAJA ATV vehicle, to be stopped within a specified distance running at a specified speed. Index Terms: Braking system, Disc brakes, Calipers, Weight Transfer, Hydraulic braking, Pascals Law. The related data is calculated and attained to extract average values for different design parameters to make the theoretical calculations as realistic as possible. ![]() This paper discusses the reverse calculation of the braking system and eventually calculates the required bore diameter of a caliper and hence apprise about most preferred caliper that should be used to have the most effective braking for a hydraulically operated braking system of a BAJA ATV. The evaluation is done by calculating the required braking torque and comparing it with the generated braking torque. The safety being priority, braking values are computed using mathematical models. Abstract: An important factor in handling of every vehicle is its effective braking, making the vehicle easy and quick to stop with complete control of its essentials in the drivers hand.
