What is brake lining pressure of brake lining?

Since the lining is the portion of the braking system which converts the vehicle's kinetic energy into heat, the lining must be capable of surviving high temperatures without excessive wear (leading to frequent replacement) or outgassing (which causes brake fade, a decrease in the stopping power of the brake).

How to Calculate Mean Lining Pressure of Brake Lining?

Mean Lining Pressure of Brake Lining calculator uses Mean Lining Pressure = (180/(8*pi))*(Brake Drum Braking Force*Effective Wheel Radius)/(Friction Coefficient between Drum and Shoe*Brake Drum Radius^2*Brake Lining Width*Angle between Linings of Brake Shoes) to calculate the Mean Lining Pressure, The Mean lining pressure of brake lining formula is defined as the pressure developed on the brake linings due to the number of forces like normal and actuating forces that act on it during braking operation. Mean Lining Pressure is denoted by mlp symbol.

How to calculate Mean Lining Pressure of Brake Lining using this online calculator? To use this online calculator for Mean Lining Pressure of Brake Lining, enter Brake Drum Braking Force (F), Effective Wheel Radius (r), Friction Coefficient between Drum and Shoe (μf), Brake Drum Radius (r_BD), Brake Lining Width (w) & Angle between Linings of Brake Shoes (α) and hit the calculate button. Here is how the Mean Lining Pressure of Brake Lining calculation can be explained with given input values -> 2143.174 = (180/(8*pi))*(7800*0.1)/(0.35*5.01^2*0.68*0.4363323129985).
