FMP Automotive Malaysia says it is possible to look at brake pads and identify wear and tear.
As an expert in the field of automotive friction materials, marketing the popular Bendix brand of products, FMP Automotive Malaysia has shared the following tips for car owners to tell whether their brake pads are running low and are due for replacement:
Look, Listen & Feel
It's possible to look at brake pads and identify wear and tear. Pads should be visible by looking through the rims of the car's wheel - the outside pad is pressed against a metal rotor. There should be at least three millimetres of the pad visible. If you see anything less, get the brake pads inspected.
This is the sound of the wear indicator (show wear indicator sample). When enough of the friction material is worn away, the wear indicator will contact the disc and make a squealing sound. This means it is time for new brake pads.
If you hear a grinding sound, that means the friction material is completely worn off. The grinding sound is cause by two pieces of metal rubbing against each other. This can scratch your disc rotor, creating an uneven surface. When this happen, don’t be surprised if your mechanic tells you that your disc rotor needs to be skimmed or even replaced.
This is added safety feature on mostly continental cars. When the brake pad wears and the electronic brake wear sensor makes contact with the rotor, a warning is given, usually in the form of a light on the vehicle dashboard.
If the brake pedal vibrates when you push your foot down on it, they could be warped due to heat.
Once you have sensed any of the above mentioned signs, what’s next? Send your car to a professional mechanic for a thorough check on your brake system! Here’s what you can expect to see in the workshop, when the mechanic is checking on the braking system (brake pad, disc rotor, brake fluid)
By visual, tools or checking at the feature on products, such as the Bendix brake wear indicator. This indicator is the latest innovation by the ‘brake expert’, Bendix. Printed on the side of the replacement Bendix brake pads, the wear indicator enables the trade to see at a glance when the brake pads are due for replacement, so simple and effective.
Disc rotors are disposable items and will need replacing around 150,000 km into their use depending on your driving style and the type of brake pads used.
Replace or Skim? This depends on the rotor’s thickness and condition. Get advice from a professional mechanic.
Brake fluid lives in a sealed system and can survive for years, but moisture from the surrounding air can work its way in through hoses and other parts of the brake system. If your brake fluid has become dirty or contaminated, it can change how your brake system operates — brake pedal feel can be affected, as can heat dissipation in repeated stops. Water in the brake lines lowers the boiling point of the fluid, so stopping ability can diminish in hard stops as heat in the system increases. In addition, over time, the moisture can cause internal corrosion in the brake lines, callipers, the master cylinder and other components.
Flushing and replacing brake fluid might cost a little extra, but replacing rusted brake lines, brake callipers and other brake parts can run to several hundreds of dollars, so clearly there's value in keeping up with maintenance. As a rule of thumb, it's wise to have the brake fluid inspected and tested for moisture content every few years.
我们能够用眼睛观察和判断刹车片是否已经摩损。从车轮轮辋看刹车片—外面的刹车片压在钢背上 。肉眼观察刹车片的厚度，至少要有 3mm左右。如果比这还少，就需要检查刹车片。
一旦你感觉到上述的迹象，那么接下来该做什么呢？将你的车子送到专业技师那里做一个彻底的刹车系统检查 ！当技师检查刹车系统（刹车片、刹车盘及制动液）时 ，你会看到：
