Question

Application of brakes wear out the brake shoes. Why

Answer 1

when we apply brakes surface area of brakes and rotating wheels comes in contact due to frictional force arise. due to frictional force brakes wear out the brake shoes

Answer 2

$\bold{\large{\underline{\underline{Answer }}}}$

1) The brakes which contains the brake shoe known as $\bold{drum\: brake}$.

2) When we apply the brake so that shoe will be $\bold{expanded}$ and opposes the kinetic energy causes application of brake.

3) These type of brakes contain friction lining made up of $\bold{ceramic}$ , thin $\bold{copper \: wires}$ and heat resistant material.

4) When we apply the brake cam rotate and expand the brake pads which causes $\bold{friction}$ in between $\bold{friction\: line}$ and drum body causes wear and tear.

5) These brake shoes have $\bold{1-4\: lines}$ are designed to reduce the heat and also help us in changing up of brake pads.

6) These brake shoes are changed according to the specified $\bold{kilometres}$.

Reason : Due to friction in between the $\bold{brake\: pads}$ & $\bold{drum\: body}$.
