Advice 1: How to check brake pad wear

The brake pads are referred to as friction linings that are pressed against the drum or brake disk and stop rotation of the wheels. You should regularly change the pads, because they wear affects the quality of braking, and hence safety of the trip.
How to check brake pad wear
You will need
  • - Jack;
  • - telescopic key;
  • - Vernier caliper or ruler.

Each car has its own criteria regarding frequency of replacement of brake pads. Basically, the drivers think that the pads require replacement after 8-10 thousand kilometers. This figure is General and fully focus on it not worth it. Each driver's individual driving style: easy driving, in this case, the pads can work up to 20 thousand kilometers, and the fans of fast driving and sudden stops necessary to change the pads already after 5-6 thousand mileage. In addition, there are many parameters that contribute to wearhave the brake pads: the quality of brake elements, environment, temperature, etc.

About weare pad indicates the presence of brake dust mixed with metal shavings on the wheel disks, and also very sharp, or, on the contrary, excessively weak inhibition, the presence of beats at the time of braking. If your car has similar problems, check the brake pads.
3
To check the degree of wearand the brake pads and front brake, set the car on a viewing hole or the Jack.
4
Telescopic wrench remove the front wheels. When checking the brake pads of the brake mechanism on the left, turn the steering wheel left and right while checking the brake system elements – the steering wheel to the right.
5
Determine the lining thickness brake pads through the inspection hole in the movable caliper bracket. If the thickness of the friction lining is 1.5 mm or less, the pads must be replaced.
6
To check pads the rear brake, put a Jack under the rear wheel and Unscrew them and remove the brake drum.
7
A caliper or a ruler to measure the thickness of the friction lining. If it is less than 1.5 mm, replace the rear brake pads.
Note
You need to change pads in the following cases: the thickness of the lining is less than 1.5 mm, the lining is poorly connected to the base, the surface of the pads greasy.

Advice 2: How to determine the pad wear

Brake pads - it is the second shift after the oil is consumable in the car. If you skip a time when you need to replace them, it can turn cars into a lot of trouble. Besides smart appliances advance warning when you need to change them.

If you feel when braking a slight runout - it just means that the service life of brake pads your vehicle came to an end. This happens because they are erased unevenly, and because of this there are various chips and cracks. Order wearusasa brake system starts making a noise and runout. Importantly, this process does not start, or may suffer brake discs. And then the repair will cost you a large amount. And spent on the repair time will increase significantly.

If the braking system starts to behave inadequately, it is also a symptom of problems in the stocks. Their wear indicates such factors as too weak or, conversely, excessively hard braking. If the wheels lock too sharply, it signals the car owner about the fact that lining wearwere eaten at 100% and the metal rubs against metal.

Another sign of the full wearand pads can serve as a brake dust mixed with metal shavings on the disks. When you look under the ROM, rate the appearance of what is there. For example, if the RAID on uniformly dark pads, so the pad still retained. If you see the metallic inclusions, it suggests that the pad is already scratch disk, and to change it it is necessary very urgently.
4
Strong whistling when braking or the sound of scratching, as if something caught in the wheel and scratching, should alert the motorist. The thing is that the brake pads have a special limiter, which as erasing brakes approaches the disk and begins to scrape on it. Hence, there is a characteristic sound. He says that it's time to change the pads, but the time you still have. And only in the case when the noise becomes continuous, you need to understand what to change pads quickly.

Advice 3: How to check brake discs

Safety is one of the main advantages of the car. The car needs to quickly accelerate, to stand on the road, but stop quickly. Disc brakes are now installed on all cars, which proves their high reliability and efficiency.

Instruction
1
Despite its advantages, the brake discs more prone to wear than the brake drum. This is due to the fact that the drive is sensitive to runout and adverse effects of the environment. From all this it follows that from time to time you will need to verify the status of the disks.
2
To check disk you'll need to do the following:
- raise the manual brake;- loosen the front wheel - Jack up of the car;- remove the wheel - rotating wheel inspect the disk from all sides. If you noticed significant burrs and cracks, then change the drive;- using micrometer, measure thickness of the brake disc. If at any point the thickness of the disc is equal to the minimum permissible thickness or even less - to change the disc.- check the runout of the disc. Install a measuring device at a distance of 5 mm from the outer edge of the disk and spin the disk. The maximum wheel runout is 0.03 mm If the runout is greater than the disk either change or grind.- check the disc for cracks and other damage.

The main problem of the brake disc is uneven thickness of the disc roughness and the curvature of the disk. Disks with such defects, you can replace, but you can counterbore them without removing. This method is the most rational.

Brakes should not be bad - it is dangerous to life. Timely diagnosis is the best way to protect yourself and those around you.

Advice 4: How to check the pad wear

During operation of the vehicle brake pads worn out. Despite the guaranteed mileage before next replacement of the front pads 10000km and rear drum – 25000км, periodically check their wear. This event will also help to determine the necessity of maintenance of the brake calipers.
How to check the pad wear
You will need
  • - Jack;
  • - a set of keys;
  • - flat screwdriver;
  • - hammer;
  • - flashlight;
  • - 2 M8 screws.
Instruction
1
Position the machine so that you can drop any wheel with at least one side. Begin testing with the front brake padsas to check their wear on disc brakes is not difficult.
2
Remove the steering wheel in the direction where you will see the amount of wearand the brake pads, tighten the handbrake and remove the front wheel. On the brake caliper there is a viewing window through which you see the remaining layer of friction material - Ferodo. If existing lighting is not visible to the material, Shine a flashlight in there. New pads the thickness of the friction lining in most cases is 10mm. When the thickness reaches 2 mm, replace the pads.
3
In addition the absolute thickness of the material, is of great importance for uniformity in wear. If the wear of the pads occurs at an angle, so one of the guides of the brake caliper is jammed. If one pad is worn much more then wedged both guides. Repair and replace are the pads, then install the wheel on the car.
4
Check out the same manner the second wheel, if at this stage it is possible. Checking front brake pads, check and back. Drum brakes are fully enclosed mechanism and it is impossible to inspect without removing the brake drums.
5
Before raising the rear wheel with the Jack, place under the front wheel bars – one front, one rear. This is because the action of the handbrake on the front wheels does not apply. Lifting the wheel, sit in the driver's seat and press the brake pedal. Holding it, remove the car with the handbrake and slowly release the pedal. Make sure the car is securely in place.
6
Remove the rear wheel. Using two M8 bolts extrude the brake drum with its seats. Here's how: in the 2 holes on the drum tighten the M8 bolts. Gradually tightening them with the Allen key, achieve the highest level gathering drum with its seats.
7
If necessary, correct it with light hammer blows through the plywood plate. When large wearof the drum is formed a lip which makes it difficult to remove the drum. In this case, through the hole in the drum or in a protective apron, using a flat screwdriver by turning the adjusting bolt, pinch the brake pads. This process is inconvenient that you have to take the pads to the touch, as no additional viewing Windows are not provided.
8
After removing the brake drum, remove it from the bolts M8. Inspect the brake pads. The initial thickness of the friction coating is 3-4mm depending on the size of the brake mechanism. When the residual cover thickness in any location of the pads is 0.5 mm or less, replace the brake pads. Uneven wearand drum brake pads is not a cause for replacement.
9
Install the brake drum, adjust brake pads. It has to be done to get a different braking force on the right and left wheels. It is simple: using a flat screwdriver, through the window in the drum or in a protective apron, turn the adjustment wheel until, until the pads touch the drum. The clamp load should be minimal, so that the drum rotated freely.
10
Install the rear wheel and do this with the second rear wheel.
