As the epidemic gradual lifting of the ban, many drivers began to return to normal car, 2020 ldquo; car life rdquo; considered officially kicked off. Driving most important thing is safety, traffic safety brake is the last protection. But with the use of the car, the brakes may not be in the best state of your brakes can continue healthy work? Wish themselves to simple judgments about.
1, see: brake pad thickness
Most vehicles now use disc brakes, as well as a part of the car is used in the front disc drum. But no matter what kind, its principles are: with a force of foot brake, brake fluid through the transmission of brake pads force, so that the friction brake pads brake discs / drums. Whether it is the kind of brake pads are the main supplies.
look at your brake pads it. New brake pads, in a thickness of about 1.5cm, a lot of ends of the brake pads are marked with the security mark, it is generally about 0.5cm. If you wear to the security scale it is even less likely that your brakes have failed at the edges.
generally recommended replacement cycle brake pads is 2 years / 40,000 km, but only for the general case, if car owners prefer to reduce acute and urgent, rough driving, but also the life of a discount.
Listen: brake abnormal sound metal
Brake abnormal sound very many, but there is a very special: [123 ]
metal scratching sound.
This is because the brake pads are buried in the lowest wear depth ldquo; rdquo ;, the alarm device is an alarm section metal member. When your brake pads friction to expose the metal parts, metal parts and brake disc friction will, if you forgot to look at the thickness of the brake pads, then grind of real time will remind you: brake pads to the limit.
heard the sound of metal friction brake, do not hesitate to quickly change brake pads, brake discs, after all, more expensive than the brake pads.
3, step: whether the brakes soften
to determine the brake by foot feels life is generally some older drivers to master, based on many years of driving experience, as well as familiar with their car. This is notIt recommends new owner uses two or three years, because the foot feeling things are more iffy.
Usually, when the brakes, the stroke feeling is short, resistance is large, which is commonly known ldquo; hard rdquo ;, because brake fluid does not need to push the brake pads to complete the over-braking action, while the brake oil itself volume-stable, stable transmission;
If the stroke length becomes, soft foot feeling, then the brake pads and a brake fluid at least a problem; if stepped on brake oil kicks softer, or brakes suddenly soft suddenly hard, it should be the brake fluid problem.
4,
See: Brake Fluid how much
brake fluids are generally 2-year / 40,000 km replacement, generally we owners can determine whether the content of the brake fluid is normal. When the liquid level above the normal position of the scale line, the content of the brake fluid is not reduced.
does not mean there is no problem of brake fluid, brake fluid hydrophilic, while our system is not a sealed brake fluid, brake fluid over time may be mixed with water and impurities deteriorated.
And when braking, brake oil temperature is extremely high, brake fluid in the case of lower boiling point impurities mixed, Boiling extremely easy. So that when we step on the brake is squeezed out of this part of evaporated gas instead of the brake oil, of course, foot feeling soft, when the brake is not working when the Spirit. This alone see, is not apparent.
Some owners now using a counterfeit brake fluid, brake fluid which is typically add alcohol, characterized in that the relatively thin; the addition of alcohol, more hydrophilic, of course, faster deterioration.
The professional evaluation criteria, brake fluid, when in an aqueous 2.5 weight percent, can not continue to use; unsealed brake fluid, even if, for two years, the water content will reach a percentage. Periodic replacement of brake fluid is very important.
5, open: determining braking situations The braking distance
no one can find the owner, open enclosed space, placing the pile cone braking distance tests on the roadside. Drying the concrete floor is generally flat, 40km braking distance should be about 9 meters, the asphalt is about 10.5 meters.
