Information - Brake discs

The safety of the driver and passengers depends primarily on the braking system. If you notice the slightest malfunction in this mechanism, then better give up on the trip, because this can lead to dreadful consequences. The entire brake system consists of pads and discs, which are equally important for the entire mechanism.

The most common car braking systems are considered the disc brakes. This means that the main element of this type of brake is a brake disk, because the force of the actuator is applied to it. Car brakes produce frictions as the main principle of action, therefore, between the disc and brake mechanism is located a block. When braking, the kinetic energy is converted into heat. That is exactly what the brake discs and pads are responsible for.

The work efficiency of the whole system depends on the distribution speed of the resulting heat. And itgets sometimes very hot. The overheating of the brake disc leads immediately to the deformation of the metal, causing the brake failure on the road. In order to avoid such consequences, it is best to take care in advance of the quality and reliability of the brake system in your car, namely, to choose the "right" discs. But it is not so simple, and the driver may have difficulties in selecting discs currently offered in the global market. Of course, the purchased items must be original, since these parts undergo strict quality control and can last for a long time.

Today you can buy original brake mechanism disks in our online store; they are of high quality and at an acceptable cost. You can also order from us other parts such as brake drum or brake pads.

All you should know about brake discs replacement: service life, common defects and their signs, tips and recommendations

Brake discs manufacturers specify their minimum permissible thickness on the parts edge. On reaching it, components are to be replaced. Usually it happens after 80 000 - 120 000 operational kilometers for the front axle discs, and 130 000 - 170 000 operational kilometers for the rear axle discs. In comparison with the rear discs, the front brake discs are more apt to wear out because they suffer more loads during braking.

Moreover, sports - drilled or slotted brake discs can also get out of order earlier.

In some cases the components should be replaced even if their thickness is more than critical. As a rule, such necessity is dependent on uneven disc wear, its deformation or cracking, appearance of shears and grooves on the surface, formation of special protrusion on the outer edge.

Screeching, creaking, vibration and beating of discs during braking point at discs defects. You can also feel loosening of the brake pedal. Moreover, if you noticed that the braking mechanism is jamming at brake pedal pressing or the car is pulled aside during emergency braking, then you must perform immediate components inspection.

The brake discs are to be checked according to schedule during every car general inspection and at pads replacement. Mechanical damages, deformation, change of the surface color point at replacement necessity. Special equipment - the dial indicator and the beam caliper - are necessary for measuring value of wobbling and residual thickness of the components. Take into account that the ventilated brake discs have more thickness than non-ventilated ones which is dependent on their construction. After having performed measurements compare data you got with values specified in car technical documentation.

For brake discs replacement remove the wheel, unscrew caliper bracket bolts and fix the caliper itself with the help of improvised tools. Remove the pads if needed and then unscrew disc fixations and demount it. When replacing components on the rear axle deactivate the parking brake and loosen its pads otherwise disc removal will be impossible. After installation of a new part, assemble the unit in the reversed order.

Components are to be replaced in pairs on every axle. That is why it is desirable to buy the brake discs kit - so you will be able to save money. Brake pads are to be replaced during new discs installation.

Important advices for our customers

What are the best brake discs for me to install on my car?

When choosing brake discs one should consider their operating conditions and cost.

  • Discs by manufacturers like Japanparts, LPR, Mapco, Icer, Ridex are afforably priced and are intended for standard, city driving.
  • A.B.S., Metzger, ABE, NK, Vaico are mid-range priced discs, intended for moderate to heavy-duty performance. They are usually the choice of sportive style drivers.
  • Premium-class discs by ATE, Zimmermann, Bosch, Textar, Brembo, Stark Professional Line withstand extreme strain and provide maximum braking efficiency. They are usually installed in powerful sports cars.

Can I replace brake discs myself?

We would definitely respond in the affirmative to that! The replacement itself is not complicated, but requires certain skills as the procedure implies removing wheels and brake calipers. If you don't have the necessary experience, it will be better to turn to professionals for help. When installing new parts, the car manufacturer's recommendations should be followed strictly.

What's the minimum thickness allowed for brake discs?

That dimension depends on the manufacturer and model of every part and is usually indicated on the side of the brake disc. Most cars would have vented brake discs in the front; they are thicker than the rear, solid ones. Measure your brake discs using a slide caliper. If the disc thickness is approaching the minimum, the disc should be replaced immediately.

When is it time to replace brake discs? Should front and rear discs be replaced at the same time?

The best way to find out if the time has come to replace brake discs is by measuring their thickness. If it is less than the prescribed minimum indicated by the manufacturer on the edge of the disc, the component should be replaced.

As a rule front brake discs endure bigger stress which wears them out faster. Discs should be replaced in sets per axle. It is recommended to install new brake pads every time the brake discs are replaced.

Would high-performance brake discs be a good choice for city driving?

Perforated and slotted brake discs would be a good fit for city driving in the following cases:

  • You enjoy assertive driving. Frequent and abrupt braking causes brake discs to overheat. Perforation and slots remove heat swiftly. After the brake pedal gets pressed several times in a row at a speed of about 80 kmph, the efficiency of regular brake discs drops significantly, while the slotted and perforated discs show great results.
  • You drive a powerful SUV. The large weight of the vehicle puts an additional strain on the braking system, causing it to overheat and leading to an eventual disc deformation.
  • You would like to give your car a sleeker look. Perforated brake discs combined with cast wheels look stylish and imposing.
