According to the three techniques Hengding noted automotive wheel hub unit, brake must be noted:
First, check the brake pads
Regardless of any brake system are ultimately the brakes (disc) or brake shoes (drum) to complete the braking effect, so to regularly check the thickness of the brake pads or brake shoes tablets. When they find it close to or less than the minimum thickness as specified by the manufacturer, should be replaced immediately. Check the brakes at the same time, also check the brakes or brake drum wear, such as exposure to dent the surface, should be promptly disc or drum, in order to ensure the contact area with the brake pads, improve braking force.
Second, check the brake fluid
(1) Before checking the brakes, carefully wipe the dirt on the master cylinder, so as not to fall into any dirt tank. Removable fasteners (typically a pin) and a lid. For no scale cylinder, the cylinder should be kept away from the top surface 6 mm, if the scale, as long as the scale level than another job can be.
(2) if found oil drop, check the brakes immediately place the oil leaks.
(3) If the brake fluid is dirty, rinse and let go of the whole system, and then fill the master cylinder with a new solution.
(4) Do not re-use brake fluid, all from the system to be let go of the brake fluid should be discarded.
(5) If the master cylinder needs to refuel, please join in line with DOT3 or DOT4 brake fluid overloaded specification. Do be careful not to paint the brake fluid on the cheap, because it has a strong corrosive, would destroy the finish.
(6) in a very long period of time if the total lack of brake fluid, but you can always add, then obviously something wrong with your brakes, you should check it.
(7) Since the brake fluid absorbs moisture from the air, a long time will fail, according to the manufacturer's requirements, periodic replacement of brake fluid, preferably replaced once a year.
(8) Clean, high quality brake fluid is a good security situation and the basic power brake system, you should buy the best quality commercially available brake fluid.
(9) in the project and maintenance of the brake system, the brakes checked regularly is the most important level, at least once a month to check, more often the better.
(10) colors brake fluid can also see the problem, the color of brake fluid should not be too deep, nor should it look like burnt. If so, then there is a problem, but this does not happen very often.
Third, the car brakes self-test three tips
According Hengding automobile hub unit learned that the car is now in addition to a simple means of transport, but also a lot of people's life partner, many friends like to play with cars in his spare time pondering the car. There are even some of my friends do not understand the car, but also hope to get more knowledge by car through the car, using this knowledge to check their vehicles. Tips self-test through some brief hope whatever, so that owners can not even replace or repair it yourself, it can be more timely understanding of vehicle information in the case can not always get a professional inspection, examination and determine their own methods of vehicles minor problems .
1, see the thickness
A new brake pad thickness is about 1.5cm, thickness with the use of continuous friction will gradually thinning. Professional and technical personnel suggest that when the thickness of the brake pads have been visually remaining original 1/3 the thickness (about 0.5cm) or so, the owner will increase the frequency of the self-test, ready to be replaced. Of course, individual models due to the wheel design reasons, do not have the conditions for the naked eye to see, you need to complete the demolition of the tire. Both sides of each brake pad has a raised flag, this flag is about the thickness of twenty-three mm, which is replacing the brakes thinnest limit, if the thickness of the brake pads have been parallel with this flag, it must be replaced. So when the brake pad thickness close to this mark when the owners should always observe the ready, but without removing the tire is difficult to accurately observed by the naked eye, there are many models in the brakes too thin handbrake lamp position when the meter will The tips, relatively self-test on convenience.
Tips:
Brake pad replacement intervals not strictly according to the car environment and driving habits, generally running around sixty thousand kilometers should consider replacing. When visually observed thinner when brakes should be required in the maintenance technician checked visually inherently exist because of errors by a professional repair station caliper more than the naked eye rigorous.
2, listen to the sound
If accompanied by "iron rub rail" tap the brakes at the same time the slightest sound, then the brake pads must be replaced immediately. Because the brake pads on both sides of the limit identity has direct friction brakes, brake pads have been proven over the limit. In this case, when replacing the brake pads at the same time to check with the brakes, the sound tends to happen brakes have been damaged, then even the replacement of the brake pads are still not eliminate the noise, serious brakes need to be replaced .
Tips:
When you hear the sound when the brakes have often already too late, when the brakes will be less damage. Brake disc brake pads to higher prices compared to many, it is recommended that you ground check brake pads, brake discs to avoid damage things appear.
3, the intensity of feeling
When the brake pads thinning our braking effect will be affected at this time need a deeper brake pedal in order to achieve the original light step braking effect can be achieved, significantly reduced braking effect before the half, a lot of people feel their brakes softened, not brake a little bit, then we must check whether the check brake pads need to be replaced.
Tips:
According Hengding automobile hub unit is understood that this method is relatively abstract, there may be some good grasp of the feel, and therefore develop a good habit of self-test is very important. Also braking effect will cause the brakes to reduce the consumption of oil increases, so replace the brake pads at the same time to focus on the inspection of brake fluid.
Summary: If you find handbrake brake performance or sensitivity is not ideal, usually by adjusting the handbrake operating copper to resolve. In the bottom of the handbrake handle with copper connections (generally covered by the interior parts) has an adjustable compensation mechanism, loosen the lock nut with a wrench, you can stretch the length of the brake copper.
