safe brake disc

QUALITY CONTROL:
SAFE brand of brake disc is manufactured under the strict quality control system of ISO9002 & QS9000: 100% inspection of material, structure, dimensions, dynamic balance and trace. 

100% balanced to prevent vibration and guarantee the utmost in safety and comfort.  Therefore, Safe brake discs provide safe, consistent, smooth braking each and every time the brakes are applied.

Smooth non-directional surface finish for quick and proper “Run-In” with pads

Surface is greased and shrink wrapped to prevent rust

METALLURGY:
SAFE brake discs meets the SAE J431 Grade 3000 material standard of gray cast iron.  SAFE discs combine specific amounts of Copper (Cu) and Chromium (Cr) blend during the alloying process to achieve the desired tensile strength and hardness.  This produces unique anti-heat fade characteristics.

CASTING:
Temperature is controlled during casting to create a uniform distribution of graphite flakes.  This results in higher wear resistance and ability to dissipate heat.

HARDNESS: HB215-187
The overall hardness of a brake disc is extremely important.  If a brake disc is too soft, it wears rapidly. Too hard, it is more likely to crack. Producing a brake disc with an uneven hardness results in uneven wear or hard spots development that cause pedal pulsation. Taking into account each of these issues is important as they affect brake performance and disc life.  Based on the Brinell Hardness Test, the ideal hardness to maximize pad and rotor life is HB210-200.  SAFE discs maintain a controlled hardness close to the ideal with HB215-187. This provides even wear between pads and rotors while delivering maximum braking ability.

Tensile Strength ≥ 210Mpa
Each batch has the right amount of carbon to achieve the desired tensile strength that minimizes brake disc warping and cracking as well as maximizes the depth of the heat damn.

Lateral Run-out < 0.05mm
Lateral run-out should not exceed 0.05mm to 0.13mm.  Lateral run-out exceeding this range can create vibration, pulsation, or brake noise.    SAFE Lateral run-out is held to less than 0.05mm

Thickness variation < 0.13mm
Lack of parallelism is a variation of the rotor thickness.   A thickness variation as little as 0.013 mm can contribute to pedal pulsation, vibrations, and brake grabbing.
