You will need: Phillips screwdriver, wire.

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.

The minimum allowable thickness of the brake disc of the brake mechanism of the front wheel of a front-wheel drive vehicle is 24.4 mm, all-wheel drive is 26.4 mm. If the thickness of one of the discs is less than the specified value, replace both discs. When replacing brake discs, be sure to replace the brake pads with a new set.

1. Loosen the front wheel nuts on the side of the disk being replaced, place wheel chocks (“shoes”) under the rear wheels. Apply the parking brake. Raise the front of the car with a jack, place it on secure supports and remove the wheel.

2. Remove the caliper without disconnecting the brake hose from it (see "Replacing the front wheel brake caliper")…

3. ... and attach the caliper with wire to the coils of the front suspension spring, avoiding twisting or stretching the hose.

4. Turn out two screws of fastening of a disk to a nave …

5. ... and remove the disc.

6. Similarly remove a brake disk of the brake mechanism of other forward wheel.

7. Install the parts in the reverse order of removal.

NOTE

Before installing the disc, carefully clean the mating surfaces of the disk and hub from rust and scale, as even the smallest particle sandwiched between the mating surfaces will cause the disc to beat and vibrate when braking.

The process of stopping the car is accompanied by a gradual wear of the front and rear discs. Their timely replacement is necessary to maintain the possibility of effective braking. At the same time, it is important to use high-quality consumables that can perform the functions assigned to them throughout the entire service life.

The original front brake discs of Kia Sportage 3 have article number 51712-2Y000. Their price is more than 5000 rubles. Branded consumables provide optimal braking performance, but have a short resource.

ATTENTION! Found a completely simple way to reduce fuel consumption! Don't believe? An auto mechanic with 15 years of experience also did not believe until he tried it. And now he saves 35,000 rubles a year on gasoline!

The new brake disc is 26 mm thick. With a run of 45 thousand km, the size of the consumable is reduced to the minimum recommended 22.4 mm. official instructions indicate the need to replace when a given thickness is reached. A sporty driving style significantly reduces the life of the original discs. Many car owners complain that they have to change consumables after barely exceeding a mileage of 30 thousand km.

Article and cost of good third-party front brake discs for Kia Sportage

The installation of original discs is accompanied not only by their low resource, but also by strong dusting of the brake pads during the lapping process. Therefore, despite the high efficiency of native consumables, drivers often prefer their counterparts from third-party manufacturers. The best products that have performed well on the Kia Sportage are listed below.

Article and estimated price for rear original wheels Kia Sportage

Rear original Sportage 3 wheels are part number 58411-3A300. Their cost starts from 3000 rubles. Consumables provide silent stopping of the machine, and are also part of the parking brake.

The rear axle has less force on the disc when the car slows down. Therefore, their resource is not so small compared to the front consumables. Replacement is usually required when the mileage exceeds 70 thousand km.

The main disadvantage of the rear original discs, which is noted by most car owners, is the appearance of corrosion spots after a short downtime. This does not affect the stopping power of the vehicle, but it detracts from the aesthetic appearance of the Sportage 3 wheels. If the rust is severe, the braking performance will still be affected.

Article and approximate cost of good analogues of the original rear discs for Kia Sportage

Experienced car owners recommend purchasing analogues from third-party manufacturers instead of original products for replacement. In this case, it will turn out not only to save money, but also to buy a disk with better performance. The best options for alternatives to native consumables are shown in the table below.

Replacing the front discs on the Kia Sportage

Replacing the front disc on Sportage 3 is carried out according to the step-by-step algorithm, which is given below.

• Jack up the front of the car, fixing the rear axle with a handbrake and shoes.
• Remove wheel.

• Unscrew the caliper and remove it.

• Remove the two screws that secure the brake disc to the hub.

• Pull the disk towards you and remove it.

• Mount a new consumable on the hub.

• Install the caliper in place, checking the condition of the pads and replacing them if necessary.
• Mount the wheel.

• Check the operation of the braking system. A decrease in its effectiveness is the norm at the time of grinding.

Step-by-step replacement of the rear discs on the Kia Sportage

To replace the rear brake discs on the Sportage, follow the instructions below.

• Engage forward gear or park mode.
• Jack up the rear of the car from the side from which the replacement of the consumable is planned.
• Dismantle the wheel.

• Loosen the caliper fasteners. Very often they stick and become covered with rust. In order not to damage the brake mechanism, it is recommended to spray the bolts with penetrating grease.
• Remove support.

• The rear disc of the Sportage 3 is integral part parking brake. Therefore, its dismantling can complicate the handbrake pads. If they cling to the inner surface of the disk, it is necessary to turn the adjusting gear with a screwdriver and remove the friction linings from the contact point. After that, pulling the consumable toward you, dismantle it.

• Check the condition of the parking brake elements and the thickness of the friction linings. Clean up disk space.

• Install new disk to the seat.

• Adjust the parking brake mechanism.

• Check pad thickness.
• Mount the support.

• Install the wheel.
• Check the operation of the brakes. Since the rear axle does not have much effect on stopping the machine, there should not be a noticeable decrease in deceleration efficiency during the break-in process.

The safety of a car consists of many parameters, and the braking system plays an important role in its active part. Each part of this system affects the overall effectiveness of the brakes. Their maintenance includes many procedures, one of which is the replacement of brake discs.

Kia Sportage brake disc and caliper disassembled

Kia Sportage brake disc replacement is usually required for the following reasons:

• Mechanical damage;
• Natural wear (development);
• Tuning.

A disc malfunction may be indicated by a decrease in the tenacity of the brakes (lengthening of the braking distance), the car moving to the side during braking, the presence of vibration when the brake pedal is pressed, and a large output on the working surface of the discs.

Needed with disks. Older pads have roughness on the running surface, which will not allow them to press firmly against the surface of the disc, which may make braking insufficiently effective. It can also damage new discs.

Changing the front brake discs

To work on the diagnosis and replacement of brake discs, you will need the following tool:

• Micrometer
• Set of keys or sockets
• Flat and Phillips screwdrivers

To begin with, we put the car on a flat surface on the handbrake and put the back wheels under the rear wheels to prevent rolling back during operation. We release a little nut of the front wheel from the side where the replacement is planned. We raise the crossover on the jack and remove the wheel.

For safety reasons, do not operate the machine while it is on a jack. It is better to keep it on special stands.

We unscrew the screw with a hole for the brake hose, and then the caliper mounting bolts. Remove the brake caliper. The disc is held on by two screws loaded from the wheel mounting side, unscrew them and remove the disc.

In order to diagnose a Kia Sportage brake disc, you need to perform three steps:

1. inspect the disc for scratches and damage
2. measure its thickness
3. check it for beat

The first two are quite easy to do, the third will require a special tool such as a dial indicator.

Front brake disc with pads

Measure the thickness of the brake disc with a micrometer of eight or more approximately equal to remote friend from other places. The thickness of the new front disc should be 26mm, the minimum thickness that meets the repair limit is 24.4mm. For Sportage with all-wheel drive, the normal thickness is 28 mm, the minimum is 26.4 mm.

To check the disc for runout, you need a device at a distance of about 5 mm from the outer edge. The maximum runout value is 0.025 mm. If the value exceeds this figure, you must reinstall the disk. If it is within the normal range, you need to turn it 180 degrees and take a new measurement. If you cannot achieve normal values, then the brake disc needs to be replaced.

Installation must be carried out in reverse order. After completing the work, you need to remove excess air from the brake circuit.

You will need: Phillips screwdriver, wheel nut wrench.

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 be at least the minimum allowable 8.4 mm. If one of the discs is less than specified, replace both discs. When replacing brake discs, be sure to replace the brake pads with a new set.

1. Remove the wheel from the side of the disc being replaced.

2. Remove the caliper (see "Replacing the rear wheel brake caliper") without disconnecting the brake hose...

3. ... and secure with wire to the body, avoiding twisting or stretching the hose.

4. Turn out two screws of fastening of a disk to a nave …

5. ... and remove the disc.

6. Similarly remove a brake disk of the brake mechanism of other back wheel.

7. Install the parts in the reverse order of removal.

NOTES

Measure the inner diameter of the parking brake drum. If it is larger than 169 mm, replace the disc.

Before installing the disc, carefully clean the mating surfaces of the disk and hub from rust and scale, as even the smallest particle sandwiched between the mating surfaces will cause the disc to beat and vibrate when braking.

12.5.2. Removing the rear brake disc

Shown is the rear brake disc mount. To remove it, you must first dismantle the caliper and caliper bracket, as described earlier. Removing the rear brake cylinder must be carried out in the following order:

Loosen the caliper mounting bolts and remove it. Tie it with wire to the rear axle so that it does not hang on the brake hose. When assembling, make sure that the brake hose is not twisted and does not rub against other parts;

Loosen the brake disc mounting bolt. When unscrewing, raise the parking brake lever, then lower it again when finished;

Before removing the disc, depress the parking brake pads. To do this, insert a screwdriver, as shown in , through the hole in the hub and remove the adjusting gear of the pads. This is necessary so that the pads move away from the drum and do not interfere with removal. Knock down the disc with a rubber or plastic hammer;

Please read the following section before reinserting a drive. Tighten the disc mounting bolt to a torque of 20 Nm, the caliper mounting bolts to a torque of 105–115 Nm. After tightening, check again that the brake hose is properly positioned.
