A sum of money that the owner of the mercedes is the most vulnerable to the pit is the phrase "the brake system should be maintained" — people are dragged to the grinding iron, and the wound is dangerous; some people are simply replaced by a bunch of non-requireable aggregates, which cost thousands of dollars to find it useless. The benz plant actually has clear periodicity and thickness criteria for the brake system, which, in terms of data, is both safe and economical。
How often do brakes change
The benz plant recommended the replacement of pre-branch films by approximately 30,000 to 50,000 kilometres and post-brand films by about 40,000 to 60,000 kilometres, but the number of kilometres is only a reference line, and the physical wear and tear speed is highly related to road conditions and driving habits. Shouldn't it really be changed, depending on the remaining thickness. Take a depth measure and change it below three millimeters. Don't just stare at the numbers on the meter。
The brake load on the front load is significantly greater than on the back wheel, the replacement cycle of the previous front disk is generally shorter than the back wheel, and four rounds of unsynchronization are normal engineering designs. All four rounds must be measured at the time of the inspection. The hindsight to the limit influences the brake balance, and even runs away at high speed, a detail that is ignored by many。
Brake oil is not a secret
The brake fluid is highly humid, and the water content rate rises every year when it is opened, and the more time it takes. Once the water content is exceeded, the boiling point drops, and the local boiling of the liquid creates aerobic resistance when the continuous brakes are compared to the long slopes below, the pedal is significantly softened and the brake distance is stretched directly. It's done every two years at a cost of $1,200。
Oil exchange shall be carried out with a brake fluid of dot4 and above that conforms to the mercedes certification and shall not be combined with the different labels, which shall be combined with a direct discount on performance. The work was carried out using specialized equipment to completely cleanse the old oil and remove the remaining air from the pipeline, which was the source of subsequent pedals. Normative processes affect the end effect more than the oil itself。
You don't have to change plates
A lot of stores have two charges for "scatter together" and the owner feels responsible. The correct approach is to measure the thickness and wear and tear of the surface prior to construction: even wear and tear, no deep trenches, thickness within the standard range, only a change of film. Don't spend an extra $23,000 on the easy way, measure it and set it up。
However, if the plate has been sharpened, partially deformed or the thickness has reached the lower limit, the plate must be changed together. The brake blades that are grinding to the backboard will scratch the face, and if they are not handled, the new ones will go up for hundreds of kilometres and shake. About 60,000 to 100,000 kilometres for the front and 80,000 to 120,000 kilometres for the back。
Don't panic
It is normal to have a rusty face after the rainy days, and the first squeaks on the brakes in the cold car and to disappear with a few feet. However, if the continuous sharpness of the metal friction is accompanied by a pedal shaking or a long journey, it means that the wear is limited or the alien is stuck in, the shop must be inspected as soon as possible。
The brakes are shaking in two ways: the high-speed brakes are shaking in the direction, most of them thermal transformation of the brakes, and they are transposed; and the low-speed brakes are shaking, which may be a loose or shift-over problem for the bottom of the ball, not related to the brakes. If you look in the wrong direction, you spend your money, and you go in front of the store and explain the symptoms。
Driving habits determine the life of the brakes
Urban congestion, frequent brakes, constant brakes on the downhills of the mountains, and heavy driving will wipe out two and a half years of normal life. There is also a hidden habit: the foot is always on the brake pedal, which is equivalent to constant light brakes that accelerate wear and tear. The downhill should be low-strengthed with a start-up mechanism, so as not to keep on the brake pedal。
There is also an easy-to-neglect inspection: brakes and hoses. Aging rubber hoses and leaks directly weaken brake performance, and screen the plate with a look at the condition of the tube. The monthly security segment is slow and slow, and feels whether the pedals are vibrating and acoustic, resulting in self-censorship through the thick lenses of the wheel。
