Determine the working position of hand brake lever and foot brake pedal, hand brake lever also has a pull. Usually, when the handle is 70% of the lift to the whole trip, handbrake brake system should be in the normal brake position, so before check handbrake brake force, should first find out the working point of 70%, the number of working point can ratchet sound to determine. Can compare car parked at the quiet place, slowly pull the handbrake, clicking sound from the side edge number of ratchet, until the handle to the end. Then calculate the noise 70% of the total number of position, the position is effective working point of handbrake lever. Check the handbrake institutions drove the rolls into the slope is bigger, the effectiveness of the road is in good condition, It is best to asphalt) Slopes, foot on the brake, the gear in neutral, If it is automatic transmission is hanging in the N block) , pull hand brake lever to determine the working point of position just now. Then loosen the brake pedal slowly, if the car without sliding, means that the hand brake performance is good. Such inspection shall be in uphill and downhill position. Test the sensitivity of handbrake besides braking efficiency, you should also check the hand brake, the sensitivity of the slope is particularly important. In the absence of slope road slowly, slowly pulling handbrake lever, feeling the sensitivity and junction of the handle. This checking method can make the handbrake body wear, check the number of times so shoulds not be too much. In the process of inspection, if they do not have the hand brake braking effectiveness, or sensitivity, can usually be solved by adjusting the operation of the hand brake wire rope. In the hand brake lever and the joint of steel cable at the bottom of an adjustable compensation mechanism, loosen the lock tight nut can stretch the length of the brake cables. But some auto adjusting mechanism is located in the car, if the inconvenience, should by professional maintenance staff to deal with. High-speed mo with the hand brake, there are many car owners think meets the braking system failure, can pull hand brake to slow down, actually it is very dangerous. Due to the hand brake mechanism is not precise, left and right sides of the braking force distribution, pull the handbrake when high speed is easy to make one side of the rear wheel lock, skid. Is the right thing by dropping gear to slow down, the speed is very low when pull the handbrake will stop the car brake.
