What Are the Reasons for the Particularly Strong Braking Jerk in BMWs?
2 Answers
Regarding the reasons and solutions for the particularly strong braking jerk in BMWs, the following points are provided: 1. Suspension System Malfunction: The front wheel shock absorbers are in a compressed state, while the rear wheel shock absorbers are in an extended state, creating a nose-diving posture with the front lower and the rear higher. After the car comes to a complete stop, the front and rear springs return to their original state, requiring the front of the car to lift slightly and the rear to lower somewhat, resulting in a jerking sensation. Solution: Increase the stiffness of the front suspension. 2. Sudden Braking: There will be a jerking sensation during sudden braking. Solution: Try to avoid sudden braking and slow down gradually when braking.
I've been driving a BMW 5 Series for three years now, and with frequent city traffic jams, I often experience strong brake judder. I suspect it might be due to uneven brake discs. BMW's brake discs are quite precise, and uneven wear or deformation after sudden braking on mountain roads can cause jerky movements with each brake application. Additionally, if the ABS system is overly sensitive or malfunctioning, it may intervene excessively during braking, increasing the judder. I remember during my last visit to the repair shop, the mechanic mentioned that regular inspection and replacement of brake pads can prevent this, along with checking the condition of the brake fluid—its degradation can cause issues. The judder isn't just uncomfortable; it can affect driving safety in the long run. So, I've made it a habit to visit a professional shop for maintenance every six months.
