Brake Disks dominate the aftermarket with first-to-market part numbers and industry-leading coverage. Brake discs are made out of unmachined castings containing flake graphite (grey cast iron). The configuration of the cast iron is based on the one of the vehicle manufacturer for brake discs. Different ingredients are added on the basic material, in order to influence positively the properties of cast iron for durability and machining.

Brake Disks

Supplements in the iron alloy like e.g. copper, molybdenum, titanium and carbon are analyzed in the OE discs and are also used for the ARIRANG discs. Therefore cast material for each individual brake disc of ARIRANG matches with the OE parts. Over the last few years, an increasing number of brake discs, which are not identical to the respective original part in terms of their design and function, have been sold on the market. Tests have revealed, that basic material specifications in particular, but also changes to tolerances result in deformations and increased cracking of brake discs. Any "cracks" in a brake disk are a bad sign for your car's brakes! The cracks happen as a result of the disks reaching high temperatures from breaking. Disks showings signs of cracking should be replaced immediately.
Samyong Co., Ltd has been performing inertia dynamometer tests and driving tests on an ongoing basis for more than 10 years, at great financial cost. On the basis of these tests, we are able to offer the free spare parts market qualitatively equivalent spare parts.
Application-specific vane configuration offers safety and performance, minimizes noise and vibration, and maximizes airflow to help keep your disk running cool. They also feature a non-directional ground finish that minimizes thickness variation and helps with brake pad life. These dependable aftermarket Brake Disks offer quality at an economical price. Whether you are looking for durability for high-performance vehicles, dependability for everyday driving situations or protection against the harshest of elements, ARIRANG has a disk for you.


The following inspections and maintenance procedures can help prevent potential brake problems:

- Regularly check brake rotor for signs of rust and visible surface ridges.

- Check brake fluid level at every oil change. Replace fluid according to owner’s manual recommendations.

- Calipers and wheel cylinders should be checked every brake inspection and serviced or replaced as required.

- Inspect the brake lines for rust, punctures, or visible leaks (You may be able to do this, but consult a qualified technician if necessary).

The following should be conducted by a qualified technician:

-Inspection of the brake hoses for brittleness or cracking.

- Inspection of brake lining and pads for wear or contamination by brake fluid or grease.

- Inspection of wheel bearings and grease seals.

- Parking brake adjustments (as needed).
