What should I do if the handbrake cable breaks
If the handbrake cable breaks, the vehicle must be stopped immediately and professional repair and replacement of the handbrake cable should be sought to avoid serious risks such as brake system failure. Temporary measures are only for emergencies and cannot replace professional maintenance.
Immediate action and temporary measures
Youdaoplaceholder0 Stop immediately : upon discovering the fracture, turn on the hazard lights and park in a flat and safe area (pull over on urban roads or move to the emergency parking lane on highways), and shift into P gear (automatic transmission) or 1 gear (manual transmission) to assist with parking.
Youdaoplaceholder0 temporary fixation :
Tie the broken part tightly with a rope and pull it tight.
Secure the wheels with wooden blocks or stones to prevent them from sliding.
These methods have limited effects and need to be repaired as soon as possible.
Professional maintenance and prevention
Youdaoplaceholder0 Replace the handbrake cable : The entire set of handbrake cables must be replaced by professionals from a 4S store or a regular repair shop and adjusted to ensure uniform force.
Youdaoplaceholder0 daily prevention :
Avoid pulling the handbrake too tightly.
Do not apply the handbrake when parking on a slope for a long time or driving at high speed.
Release the handbrake before starting.
When the handbrake cable is frozen, the fastest solution is as follows:
The method of defrosting the mechanical hand brake wire
Youdaoplaceholder0 reverse impact method
If there are no obstacles around, shift into reverse gear and press the accelerator hard to use the vehicle's power to forcibly break through the frozen handbrake wire. This method is suitable for situations where the freezing is relatively light and safety must be ensured.
Youdaoplaceholder0 hot water pouring method
Prepare hot water (to avoid scalding the skin), pour it over the rear brake discs or handbrake calipers, and gently tap and vibrate to accelerate the thawing process. Be careful not to pour it directly onto the tires or rims.
Youdaoplaceholder0 pull pull pull
Find the handbrake cable behind the wheel and pull it back and forth several times with force to restore its flexibility through physical external force.
Precautions
If the above methods are ineffective, do not forcibly drag or hammer the components to avoid breaking the handbrake wire or deforming the calipers.
When parking daily, avoid parking in waterlogged or damp areas. Regularly check the lubrication of the handbrake system to reduce the risk of freezing.
The main function of the handbrake cable is to transmit the driver's braking command to the rear wheels of the vehicle, achieving parking braking through mechanical structure. When the handbrake is pulled, the steel wire rope applies braking force to the rear wheel brake shoes or brake discs through the transmission device, preventing the vehicle from rolling back or sliding.
Structure and working principle
Handbrake cables are usually made of steel wire or similar materials and connect the handbrake lever in the driver's cabin with the rear wheel braking system. When the handbrake is pulled, the steel wire rope is tightened, and the force is transmitted to the rear wheels through the mechanical structure, causing the brake pads to adhere to the brake discs or drums and generating braking force.
Precautions
Youdaoplaceholder0 Long-term use will wear out : After long-term use, the steel wire rope may undergo plastic deformation or breakage, resulting in a decline in the braking effect of the handbrake.
Youdaoplaceholder0 Regular inspection : It is necessary to check whether the pull wire is loose, jammed or worn, especially in damp environments or frequent usage scenarios, maintenance should be strengthened.
Youdaoplaceholder0 Different types of differences : Traditional mechanical hand brakes use a pull wire structure, while electronic hand brakes achieve similar functions through motors and sensors, but the principles are similar.
