How to Fix Front Shock Absorbers Not Rebounding?
2 Answers
Methods to repair front shock absorbers of an electric bicycle that do not rebound: Try replacing or adding hydraulic oil. Reasons why front shock absorbers may not rebound are as follows: 1. After long-term use of the vehicle, oxygen and moisture from the air enter the hydraulic system, reacting with the hydraulic oil and causing it to become turbid; 2. Continuous consumption of hydraulic oil leads to insufficient remaining quantity. The functions of shock absorbers are as follows: 1. Support the vehicle body. 2. Transmit various reaction forces from the road surface to the vehicle body. 3. Mitigate body impact and reduce body vibration. 4. Suppress vehicle bouncing, improve tire contact with the ground, and ensure vehicle safety.
I find it quite frustrating when the front shock absorbers don't rebound properly, as it affects driving safety. First, try pressing down on the front of the car a few times by hand to see if the shock absorbers can rebound normally; if they're stuck or completely unresponsive, it might be due to internal piston sticking or oil leakage. I usually check for any oil stains nearby, which would indicate a failed oil seal causing leakage. If it's just a slight sticking issue, you can try adding some specialized lubricant to clean the piston rod yourself for temporary relief, but in most cases, replacing the shock absorber is necessary. I recommend not delaying and taking it to a professional repair shop immediately, as failed shock absorbers can lead to unstable steering, longer braking distances, and are especially dangerous at high speeds. Remember, safety comes first—if you're not familiar with DIY repairs, you might end up damaging more components. Additionally, having technicians test shock absorber performance during regular maintenance can prevent such issues. In short, early action and avoiding risks are key.
