If available on working surface scuffing disk, deep scratches and other defects that increase pad wear and reduce braking efficiency, as well as in case of increased lateral runout disc that causes vibration when braking, replace the disc. In specialized workshops, such a disc can be machined and polished on both sides to the same depth, but after processing, the thickness of the disc must not be less than the minimum allowable.

If one of the discs is less than the minimum thickness, replace both discs. When replacing brake discs be sure to replace brake pads new kit.

You will need a Phillips screwdriver.

1. Engage 1st gear (move the selector automatic box gears in the "P" position) and install wheel chocks("shoes") under the front wheels.

2. Loosen the fastening nuts rear wheel.

3. Pick up and install back car on supports. Completely unscrew the fastening nuts and remove the wheel.

4. Remove the caliper assembly (see "Replacing the caliper disc brake mechanism rear wheel, p. 190) without disconnecting brake hose and drive cable parking brake, and secure with wire to the body without twisting or pulling on the hose.

5. Turn out the screw of fastening of a brake disk to a nave of a back wheel...

6. ...and remove brake disk from the hub. parking brake located in the saloon

7. Install the brake disc in the reverse order of removal.

NOTE

Before installing the disc, carefully clean the mating surfaces of the hub from rust and scale ...

If there are scuffs, deep scratches and other defects on the working surface of the brake disc that increase pad wear and reduce braking efficiency, as well as in case of increased lateral runout of the disc, causing vibration during braking, replace the disc. In specialized workshops, such a disc can be machined and polished on both sides to the same depth, but after processing, the thickness of the disc must not be less than the minimum allowable.

If the thickness of one of the discs is less than the allowable one (see Table 1), replace both discs. When replacing brake discs, be sure to replace the brake pads with a new set.

To replace the brake disc front wheel carKIARioYou will need:

Phillips screwdriver.

1. Brake the car with a parking brake and install wheel chocks (“boots”) under the rear wheels.

2. Loosen the wheel nuts.

3. Raise and place the front of the vehicle on stands. Completely unscrew the mounting nuts and remove the wheels.

4. Remove stopping support assembled with the shoe guide without disconnecting the hose from brake cylinder(see "Replacing the front wheel brake caliper").

5. Hang the caliper on a rope or wire to the parts of the front suspension. Make sure that the brake hose is not kinked or overstretched.

6. Turn out two screws of fastening of a brake disk to a nave of a forward wheel …

7. ... and remove the brake disc.

NOTE:

If difficult to remove, tap the disc with a rubber or polymer mallet.

8. Install the brake disc and removed parts in reverse order.

NOTE:

Before installing the disc, carefully clean the mating surfaces of the hub from rust and scale ...

…and the brake disc, as even the smallest particle caught between the mating surfaces will cause the disc to wobble and vibrate when braking.

If there are scuffs, deep scratches and other defects on the working surface of the disc that increase pad wear and reduce braking efficiency, as well as in case of increased lateral runout of the disc, causing vibration during braking, replace the disc. In specialized workshops, such a disc can be machined and polished on both sides to the same depth, but after processing, the thickness of the disc must not be less than the minimum allowable.

If one of the discs is thinner than the specified thickness, replace both discs. When replacing brake discs, be sure to replace the brake pads with a new set.

REPLACEMENT OF BRAKE DISC AND PADS KIA in Moscow

braking system refers to the main devices for ensuring the safety of driving. For this reason, failures brake system of the car are the very first in the list of all defects, in the presence of which it is forbidden to operate the car.

Working system- in terms of efficiency and application is the main one. The direct purpose of the main braking system of the car is to reduce the speed of the car or stop it. The principle of operation of the system is based on the compression of a rotating disk or a wheel drum spacer with special brake pads, which are compressed or released by the brake pedal through a reinforcing hydraulic system pressure transmission.

Brake discs with pads- one of the main elements of the brake systems, which, in the process of slowing down and stopping the car, convert the kinetic energy of movement into heat, resulting from the friction of the pads on the discs. To improve heat dissipation, and hence increase braking efficiency, discs with a ventilation system in the form of internal channels (ventilated) are used.

Replacing KIA brake discs and pads in Moscow at Respect Auto cost:

RIO, SIID, Picanto, Soul, Magentis, Optima, Quoris front 1750 rubles, rear 2000 rubles

Sportage, Sorento, Mojave front 1890 rubles, rear 2160 rubles

Types and causes of malfunctions

First of all - This normal wear and tear working surface due to pad friction on the disc. The pad wears faster, the disc wears slower. This process can be somewhat accelerated or slowed down due to driving style.

The need to repair or replace the disc arises when: deformation of the disc 1, uneven thickness around the circumference 2, the formation of "shoulders" 3.

Cause accelerated wear disc may have brake pads with poor quality linings (another mixture with big amount solids, etc.)

Ways to restore the tomosis system of a car:

According to the requirements of some automakers, brake discs are not repairable. Nevertheless, there is equipment that allows you to eliminate some of the defects that occur during operation. So, by turning (without dismantling or after removal from the machine), the shoulders and grooves are removed, which reduces the process of grinding in new pads and increases the efficiency of the brake system as a whole. When turning, the minimum layer of material is removed simultaneously from both sides of the disk. In the event of a runout, this part must only be replaced. The bead can sometimes be removed with a regular file, which is pressed against the untwisted disk. But the human hand in this situation is not a very reliable tool..

Accordingly, the main, but as noted above, not the only way to repair remains the replacement of Hyundai brake discs and pads.

If one of the discs is less than the minimum thickness, replace both discs. When replacing brake discs, be sure to replace the brake pads with a new set.

To replace the rear wheel brake disc car KIA Rio you will need:

Phillips screwdriver.

1. Engage 1st gear (transfer the automatic transmission selector to the “P” position) and install wheel chocks (“boots”) under the front wheels.

2. Loosen the rear wheel nuts.

3. Raise and place the rear of the vehicle on stands. Completely unscrew the fastening nuts and remove the wheel.

4. Remove the caliper assembly (see “Replacing the rear wheel disc brake caliper”) without disconnecting the brake hose and parking brake cable, and secure with wire to the body, avoiding twisting or pulling the hose.
