Brake pads. In the automobile brake system, the brake pads are the most critical safety parts, all the brake effect is good or bad brake pads play a decisive role.
In general, a new thickness of the brake pad is generally about 1.5cm, with the use of constant friction thickness will gradually become thin. When the naked eye to observe the thickness of the brake pad has only the original 1/3 thickness (about 0.5cm) or so, the owner will increase the self-test frequency, ready to change.
The following three self-test tips are a few simple self introduction method, so that even if the owners can not replace or repair their own hands, but also to check and judge their own small vehicle problems.
1, see the thickness
A new thickness of the brake pad is generally about 1.5cm, with the use of constant friction thickness will gradually become thin. Professional technical staff suggested that when the naked eye to observe the thickness of the brake pad has remained the original 1/3 thickness (about 0.5cm) or so, the owner will increase the self-test frequency, ready to change. Of course, due to the design of individual models due to wheel design, do not have the naked eye view conditions, the need to remove the tire to complete
Each brake pads on both sides of a sign of protrusions, the logo of the thickness in two or three mm or so, this is the replacement of the thin disc brake limit, if the brake pads have thickness with this symbol in parallel, must be replaced. So when the brake pad thickness close to the mark, the owner will be observed at any time to prepare, but without dismantling the tyre case by the naked eye is difficult to observe, at present many models instrument in the brakes too thin the handbrake lamp position will have some easy tips, relative self.
Small proposal: brake pads according to the car environment and driving habits are not strict replacement interval, generally about sixty thousand kilometers to consider the replacement. When the observed brake should be thinner in the maintenance requirements of the technical staff to check, because the eye will have errors, professional maintenance station through the caliper than observed more rigorous.
2, listen to the sound
If the tap the brakes with "iron iron rub" sibil, this brake must be replaced immediately. Because the brake pads on both sides of the mark has been directly on the brake disc, brake pads have exceeded the limit. In this case, the replacement of the brake at the same time to check the brake disc, brake disc sound often has been damaged, even if the replacement of a new brake still cannot eliminate noise, serious when need to replace the brake disc.
Tips: when you hear the sound of the brakes are often too late, when the brake disc will be more or less damaged. The price of the brake disc is much higher than that of the brake disc, so it is recommended that you frequently check the brake pads, to avoid damage to the brake disc.
3, the feeling of strength
When the brake is thin the braking effect we will be affected, the need of a deeper on the brake pedal to reach the original light on the braking effect can be achieved, the first half of the braking effect is weakened, many people feel a little soft brake, brake, then we must check whether the brake in need of replacement.
Tips: this method is relatively abstract, with the feeling may be some bad grasp, so develop a good habit of self inspection is very important. In addition, the brake effect will reduce the brake oil consumption increases, so replace the brake pads at the same time to focus on checking the brake oil.
