Bonfring International Journal of Industrial Engineering and Management Science, Vol. 7, No. 1, March 2017 5 Abstract--- In enhanced temperature control in disc brakes, the problems regarding the heat generation in the disc brakes have been taken into account and their solutions are provided. The notification of the temperature raise of the disc brakes is made available to the driver when the temperature reaches above the safe value. In addition, the problem of heat generation is minimized by using the forced convection technique. It is concluded that the heat generated due to friction between the disc and the pad should be minimized to avoid the loss of friction coefficient between the disc and the pad and to avoid the temperature rise of various brake components and brake fluid vaporization due to excessive heating. Keywords--- Disc Brakes, Temperature Problem, Convection Principle. I. INTRODUCTION Brake is a mechanical device that inhibits motion by absorbing energy from a moving system. It is used for slowing or stopping a moving vehicle, wheel, axle, or prevent its motion, most often accomplished by means of friction. A disc brake is a type of vehicle brake employing the friction of pads against a disc which is attached to the wheel. It uses calipers to squeeze pairs of pads against a disc in order to create friction that retards the rotation of a shaft, such as a vehicle axle, either to reduce its rotational speed or to hold it stationary. The energy of motion is converted into waste heat which must be dispersed. Hydraulic disc brakes are the most commonly used form of brake for motor vehicles. When compared to the drum brakes, the disc brakes are good in their performance but they have some limitations too, which reduces their attractiveness to some degree. So our project aims to rectify these limitations in order to improve the attractiveness of the disc brakes. The aims of this project are as follows: (i) To warn the driver when the temperature of the disc elements reaches above the safe value (ii) To reduce the temperature raise in the disc brakes by the forced convection technique P.

Brake Rotor or Brake Disc A rotor is a round disc that is made of metal or can be made of composite carbons and ceramic materials. A rotor is clamped by the caliper and the brake pads when the brakes are applied. This in turn slows the wheel. b. Brake Pad A thin block of friction-producing material, that presses against a vehicle’s brake disc or rotor to enable the wheel to stop. They are made up of materials like Non-metallic materials (cellulose, aramid, PAN, sintered glass), Semi- metallic materials (synthetic mixed with some proportion of flaked materials), Fully-metallic materials (composed of sintered steel without any synthetic additives) and ceramic materials (composed of clay and porcelain bonded to copper flakes and filaments). c. Caliper The brake caliper is the assembly which houses the brake pads and pistons. The pistons are usually made of plastic, aluminum, or chrome plated steel. d. Master Cylinder The master cylinder is a control device that converts non- hydraulic pressure (commonly from a driver’s foot) into hydraulic pressure. This device controls slave cylinders located at the other end of the hydraulic system. e. Brake Fluid The fluid used in a brake system to transmit pressure from the brake pedal to the pistons at each wheel, producing the braking action f. Temperature Sensor A temperature sensor is a device, typically a thermocouple or RTD, which provides for temperature measurement through an electrical signal. A thermocouple made from two dissimilar metals that generate electrical voltage in direct proportion to change in temperature. g. Nozzle A nozzle is a device designed to control the direction or characteristics of a fluid flow (especially to increase velocity) as it exits (or enters) an enclosed chamber or pipes. A nozzle is often a pipe or tube of varying cross sectional area and it can be used to direct or modify the flow of a fluid (liquid or gas). Enhanced Temperature Control in Disc Brakes P.
