Steel Shoes

A braking system is composed of type disc brakes, which are commonly used in the front wheels and drum brakes that are used in the rear wheels. They are connected by a series of tubes and pipes attached to each wheel brake and master cylinder. This mechanism is responsible for stopping or slowing the vehicle in motion. This is done by absorbing the kinetic energy of the vehicle and turns it into heat that is created due to friction as the brake is engaged. Disc brakes consist of the brake caliper, piston, brake pads and the disc rotor. While in your Mazda have drum brakes, it is composed of the back plate, brake drum, wheel cylinder, return springs, the automatic or self-adjustment, and brake shoe Mazda. On a disc brake when the brake pedal is pressed, the hydraulic master cylinder is fed into the brake caliper where it pushes on the piston and allows it to compress the two brake pads against the brake rotor . As the plates rub against the rotor, friction is created which is sufficient to stop or slow the rotation of the wheels.

With drum brakes, the process is executed in a different way. When the brake pedal is engaged, the hydraulic fluid is forced under pressure into the wheel cylinder and allows him to push the Mazda brake pad so that friction material rubs against the drum, causing the wheel to stop . When the pressure is released, the springs is the sole obstacle to its resting position. Since the friction is created each time the pads in contact with the drum, they wear out and possibly causing the shoe to travel a greater distance to reach the drum. If the distance reaches its predetermined position, an automatic adjustment mechanism will automatically react and do the work for adjusting the position of rest of the shoe so it is closer to the drum to achieve the proper braking operations. The brake shoe consists of a steel runner who is destined for a friction material riveted or connected to it. Like the disc pads, friction linings may wear with time and place will be necessary. If the coating is not checked regularly and is allowed to wear down to bare metal in the shoe, it causes serious damage to the drum.

The most common service required for drum brakes is the replacement of brake pad Mazda . Some drum brake design has an inspection hole on the back that lets you see how much friction material is left so that you can determine if a replacement is already needed. The brake shoe is recommended to be replaced if the friction material is worn to less than 1 / 32 inch (0.8 mm) rivets. If the friction material is related to the plate (no rivets), it is recommended that the brake shoes to be replaced when it has only 1 / 16 (1.6 mm) of friction material left. The help of a worn brake shoe for a prolonged period may allow the rivets holding the friction material to support the cause wear grooves in the drum. A badly perforated drum may be repaired by machining to smooth its surface. However, if the machine it would exceed its allowable thickness, it is necessary to have it replaced.
