The braking system is one of the most critical components of vehicle safety, ensuring road traffic safety, enhancing vehicle performance, and meeting regulatory requirements. Regular brake maintenance is essential to prevent brake failure and ensure optimal performance.
This guide covers common brake system problems, their causes, and troubleshooting tips for both parking brakes and wheel brakes.
Causes:
Gap too small or improperly adjusted
Return spring failure or breakage
Camshaft stuck or corroded
Solutions:
✔ Adjust the gap between the friction pad and brake drum.
✔ Replace the return spring if damaged.
✔ Clean and lubricate the camshaft to remove rust and dirt.
Causes:
Worn or burnt friction pads
Oil contamination on brake drum or friction pads
Solutions:
✔ Sand off burnt layers on the friction pads.
✔ Clean oil stains with gasoline and sand off deep oil marks.
Causes:
Damaged oil slinger or oil seal
Solution:
✔ Replace damaged seals to prevent leaks.
Causes:
Faulty spring brake chamber
Control pipeline leak
Manual valve failure
Solution:
✔ Inspect and repair each component systematically.
Parking brake
| Error 1 | Cause Analysis | Troubleshooting | |||
| Hand brake drum is hot | 1 The gap is too small or improperly adjusted | 1 Readjust and increase the gap between the friction pad and the brake drum | |||
| 2 Return spring failure or breakage | 2 Replace the return spring | ||||
| 3 Camshaft stuck or corroded | 3 Remove the cam, remove dirt and rust, and add grease |
| Error 2 | Cause Analysis | Troubleshooting | |||
| Braking is not possible or is weak | 1 The friction plate is severely worn or burned. | Use sandpaper to remove the burnt layer of the brake shoe friction plate, change the assembly angle of the swing arm or adjust the swing arm, and connect the nut with the pull rod. | |||
| 2 There is oil stain on the friction plate or the inner surface of the brake drum | Use gasoline to clean the oil stains on the friction plate and brake drum surface, and use sandpaper to remove the oil marks that have penetrated into the friction plate. |
| Error 3 | Cause Analysis | Troubleshooting | |||
| Oil Leakage | Oil slinger and oil seal damaged | Replace damaged parts | |||
| Error 3 | Cause Analysis | Troubleshooting | |||
| Parking brake cannot be released | The spring air chamber fails or the control pipeline leaks or the manual valve fails | Check and exclude one by one |
Possible Causes: Air in brake lines, worn brake pads, or low brake fluid.
Solution: Bleed brakes, replace pads, or refill brake fluid.
Check if one brake is faulty (binding or not working).
If all brakes are jerky, inspect the operating mechanism.
Check brake mechanism and tire condition (uneven tire wear can affect braking).
Caused by worn or glazed friction pads.
Solution: Replace brake pads or resurface rotors.
✅ Check brake fluid levels regularly.
✅ Inspect brake pads and rotors for wear.
✅ Clean brake components to prevent rust and contamination.
✅ Test parking brake efficiency on inclines.
A well-maintained braking system is vital for vehicle safety and optimal performance. Recognizing early signs of brake failure and performing regular maintenance can prevent accidents and costly repairs.
