In the article we will consider checking the braking mechanisms of the car

Checking the wear of brake discs and pads

If the car moves away when braking or extraneous noise is heard, you need to check the condition of the pads

We prepare the car and install it on the observation ditch or lift

Removing the front wheel

Checking Mazda brakes 6

Check the condition of the pads through the hole in the brake bracket housing

If the thickness of the friction pads is less than the permissible value, replace the brake pads

Dimensions of brake pads and discs, mm

The diameter of the front wheel brake disc is 299.0

Rear wheel brake disc diameter - 280.0

The nominal thickness of the front wheel brake disc is 25.0

The nominal thickness of the rear wheel brake disc is 10.0

The minimum permissible thickness of the front wheel brake disc during wear is 23.8

The minimum permissible thickness of the rear wheel brake disc during wear is 8.0

The maximum beating of the disc of the front and rear wheels is 0.1

The minimum permissible thickness of the friction lining of the front wheel brake pad during wear is 2.0

The minimum allowable thickness of the friction lining of the rear wheel brake pad during wear is 1.5

Checking Mazda brakes 6

We measure the thickness of the brake disc at eight points evenly spaced around the circumference (through 45 °), approximately 15 mm from the outer edge of the disc

If its thickness is less than acceptable, replace the brake disc

In the same way, we check the degree of wear of the brake pads and the brake disc of the rear wheel

Parking brake check

The parking brake (handbrake) must hold the car at a slope of 25% when moving the lever in the car interior by 3-6 clicks (teeth) of the ratchet device

Checking Mazda brakes 6

To check the correct adjustment of the parking brake, we find an overpass with a height of H = 1.25 m with an entrance length of L = 5 m. This ratio corresponds to a slope of 25%

If there is no such ramp, then for a simplified check of the parking brake, we install the car on a flat platform

We set the gearshift lever to the neutral position, lift the parking brake lever completely in the cabin

We get out of the car and try to move the car from its place. If you have succeeded, you need to adjust the parking brake drive
