What's wrong with the handbrake? Cause analysis and solutions
Recently, discussions about vehicle handbrake issues have become increasingly popular on major automotive forums and social platforms. Many car owners reported that the handbrake could not be pulled up or could not be fixed after being pulled up, which caused trouble in daily use of the car. This article will combine the hot topics on the Internet in the past 10 days to provide you with a detailed analysis of the common causes and solutions of handbrake failures.
1. Common reasons why the handbrake cannot be pulled up
| Ranking | Cause of failure | frequency of occurrence | Typical symptoms |
|---|---|---|---|
| 1 | Handbrake cable stuck/rusty | 42% | The pulling resistance is large and there is abnormal noise |
| 2 | Excessive brake pad wear | 28% | The handbrake stroke becomes longer and the braking force decreases |
| 3 | Mechanical failure of handbrake mechanism | 18% | The button cannot pop up and cannot be pulled at all |
| 4 | Winter freeze (northern areas) | 9% | Appears seasonally and recovers after thawing |
| 5 | Improper modification | 3% | Abnormality occurs immediately after modification |
2. Fault characteristics of different models
| Vehicle type | Frequently asked questions | Repair cost reference |
|---|---|---|
| Japanese family cars | The cable is stuck | 200-500 yuan |
| German luxury car | Electronic handbrake module failure | 1500-3000 yuan |
| Domestic SUV | Abnormal wear of rear brake pads | 300-800 yuan |
| American pickup truck | Mechanical mechanism is rusty | 400-1000 yuan |
3. Emergency handling methods
1.Winter Freeze:Use warm water to pour the brake drum area (be careful to avoid electronic components), or park it in an underground garage to let it thaw naturally.
2.Cable stuck:Try to pull and release it several times, and spray it with WD-40 lubricant (professional operation required).
3.Temporary parking:Put the automatic gear in P gear + wheel chock, and the manual gear in reverse gear + wheel chock. Send it for repair as soon as possible.
4. Maintenance suggestions and precautions
1.Self-test steps:Check the handbrake lever stroke (normally 6-8 teeth), listen for abnormal friction sounds, and observe the brake pad thickness (not less than 3mm is recommended).
2.Maintenance cycle:Ordinary mechanical handbrakes are recommended to be inspected every 3 years or 60,000 kilometers; electronic handbrakes require regular system resets.
3.Professional maintenance:When it comes to brake pad replacement or electronic system failure, you must go to a 4S shop or professional maintenance point to deal with it.
5. Preventive maintenance measures
| Maintenance items | Operational points | Recommendation cycle |
|---|---|---|
| Wire lubrication | Use special brake line lubricant | 2 years/40,000 kilometers |
| Brake pad inspection | Measure thickness + clean up debris | 1 year/20,000 kilometers |
| Mechanical anti-rust | Apply high temperature anti-rust grease | before rainy season |
| Electronic system testing | Dedicated diagnostic instrument reads fault codes | 1 year/time |
6. Hot topics of discussion among netizens
1. The failure rate of electronic handbrakes for new energy vehicles is 17% higher than that of traditional mechanical handbrakes (voting data from an automobile forum)
2. 85% of maintenance technicians recommend that if you hear more than 8 "clicks" when the handbrake is pulled up, it should be inspected.
3. The most bizarre case: A car owner was unable to pull up the handbrake because a perfume bottle in the car got stuck in the handbrake mechanism (Tik Tok hot list)
Special reminder: If the handbrake completely fails, please use the emergency brake immediately (slowly pull the handbrake while applying the brakes) and call for roadside assistance. Safety is no small matter, and timely maintenance is the fundamental solution.
