Big Dipper crossed perforated plate, black conversion disc

The original bit installation, without any changes, direct replacement installation, strengthen quality material, high friction coefficient, can greatly enhance the braking effect, rapid cooling on a hot day, rain and snow quickly exclude water. Vehicle brakes in the road, there will be trembling feeling. This is what many motorists headaches, in fact, this is the brake discs is a problem, use a timeout brakes appeared uneven phenomenon. That Face brakes and shaft mounting surface is uneven, should be replaced with new brakes. Some say that for the new brakes are jitter, and why? This is caused by the low quality of the disc. Face mounting reference unbalance and brake light car brakes Generally speaking between 0.08MM ~ 0.12MM, other models in the range of 0.1 to 0.15. If you exceed this error occurs between the brake disc brakes swings produce brake jitter. If you use a high-precision brakes will not appear on this phenomenon, our brakes machining precision 0.03MM ~ 0.08MM so no jitter, can be 100 percent assured. Advantages perforated brake discs 1. scribe scribing enables brakes as soon as possible because the dust generated by friction brake pads and dispersed into the air by a scribe groove, so as to avoid the generation of dust due to rolling friction, improve the brakes and brake the friction between the sheets. 2. Punch holes through the surface of the brake, improving air flow rate and thermal efficiency of the brake disc surface, prevent heat build-up, affect the braking effect, but also the heat transfer through the rim not too much to the tire, reduce high temperature puncture risk. 3. Punch crossed plate when driving in the rain, because there are openings and slotted, can effectively avoid the water film lubrication to prevent brakes less effective, as in the sunny air travel can reduce air film generated, thereby improving braking effect . 4. perforated brake discs crossed the heat dissipation. Prevent during braking due to high temperature deformation leads to brakes and brake effect is reduced, but can also rust and corrosion and prolong life.
