Handbrake for small cars, have a plenty of after the gearbox, and has a brake disc drive shaft connection, like a disc brake (of course, there are drum), and then through the wire, will pull to the transmission, so as to realize the parking brake.
Pull the handbrake, it USES a hydraulic auxiliary cylinder, promote the total hydraulic cylinder motion at the bottom of the car, and then drive the valve, (are so design in order to bridge does not hear the voice of the air), then after valve action, brake shaft, auto hand brake brake shaft, only after the complete brake shaft, if is ordinary truck with a handbrake lever of wire rope pull pull to realize brake for a long time, if it is more upscale trucks, Volvo, for example, use the electrical control, when you push a handbrake above, in fact there is an electric machine is started, he grew closer after completion of the air brake rope and lock, of course, there are direct pull brake.
One, the side pull the car hand brake listen to send the "click" sound, until the handle pulls to the end, then calculates the 70% of the noise total position. This position is the effective work point of the car brake.
Generally five to seven is a normal position. Then, check the effectiveness of the car handbrake, which is to see if the hand brake can work effectively.
Three, drove the rolls into the slope is bigger, the slopes of the pavement in good condition, on the brake pedal, GuaKongDang, pull car hand brake to determine the working point of position, just slowly loosen the brake pedal, if the car was sliding, means that the hand brake performance is good. Or the car will slide slightly, but the distance of the slip is small, and the efficiency of the hand brake is normal.
Four, uphill and downhill should be done each time, if find the brake efficiency of the brake of the car brake or the sensitivity is not ideal, can be solved by adjusting the pull of the handbrake. It is best not to do it yourself, should go to the repair shop as soon as possible to be handled by professional maintenance personnel.
