In the process of using a car parking will certainly use the handbrake. Because the driver leaves the vehicle, if not with the hand brake, then the vehicle is likely to slide and may cause an accident. Sometimes, the handbrake has pulled up, but because the brake system failure resulting in the accident. So the majority of riders should be regularly on car brake maintenance and check for proper use of Auto Diagnostic Tool. Here we introduced under the normal maintenance of the handbrake.

Handbrake lever operating position is determined
Like with the foot brake pedal, handbrake handle also has a pull stroke. Typically, when pulling the handle 70% of the entire trip, the handbrake system should be in a normal braking position, so before check braking handbrake should first find out that 70% of the working point, this work can be done through to determine the number of ratchet sound. Cars can be parked in relatively quiet place, and slowly pull the handbrake, the number of clicks while pulling ratchet issued until the end of the handle pulled up. Then calculate 70% of the total sound position, this position is the effective operating point handbrake handle, if you want to save time friend, you can use the Launch X431 PAD or Launch X431 V Pro tool detected 70 percent of the work position.

Check the handbrake mechanism Effectiveness
The car drove into a larger slope of the ramp on the road in good condition, slam the brakes, in neutral (if the automatic transmission is hanging in the N block), will work to pull the handbrake lever position just determined. Then slowly release the brake pedal, if the car does not slip occurs, it shows the effectiveness of the handbrake is good. Uphill and downhill should be done once each.

Test sensitivity handbrake
In addition to the braking efficiency, should also check the sensitivity of the handbrake, this is particularly important for the initial slope. In the absence of the slope on the road to slow down, slowly pulling handbrake handle, the handle and the sensitivity to feel joint. This method will make the handbrake mechanism wear, so check the number should not be too much. In process inspection, if found unsatisfactory handbrake brake efficiency or sensitivity can usually be by adjusting the handbrake operation cable to solve. The hand brake handle and the bottom of the cable connection (generally by the interior cover) with a tunable compensation mechanism, with wrench, loosen the lock nut, you can stretch the brake cable length. Some auto adjusting mechanism is arranged at the bottom, if inconvenient adjustment should by professional maintenance personnel to deal with, can also use Autel MaxiSys Pro MS908P or Autel MaxiScan JP701 tools to deal with.
