What Causes the Steering Wheel to Pull to One Side When Braking?
2 Answers
The reason the steering wheel pulls to one side when braking is due to uneven braking force between the left and right sides. If this occurs, it is necessary to have it adjusted at a professional facility. The braking system of a car is crucial as it directly affects the vehicle's driving safety and stability. The braking system mainly consists of a vacuum booster, master cylinder, wheel cylinders, brake pads, and brake discs. Methods for maintaining the braking system include: 1. Using professional brake disc cleaner—shake the can thoroughly before use and spray directly onto the areas needing cleaning until dust and oil stains are completely removed, then wipe clean with a clean towel, leaving no dust or residue; 2. Using professional brake caliper guide pin lubricant—wear a single-finger glove and apply the product evenly on the surface of the brake caliper guide pins and inside the guide pin grooves, avoiding mixing with other mineral lubricating oils; 3. Using professional high-temperature resistant brake pad protectant—wear a single-finger glove and apply the product evenly on the back of the brake pads and inside the sliding grooves at both ends of the pads; 4. Using professional high-temperature anti-seize lubricant—wear a single-finger glove and apply the product evenly on each tire bolt and the metal contact surfaces between the wheel rim and hub.
I've been driving for over a decade and have experienced brake pulling issues. At first, I thought it was just uneven road surfaces. Upon inspection, I found the left front tire pressure was a full 10 psi lower than the right front tire, causing uneven braking force that pulled the steering wheel to the left. Besides tire pressure problems, uneven brake pad wear is also a common cause. For instance, my old car had completely worn-out right-side brake pads while the left side still had over half remaining, creating a significant difference in braking force between the two sides. Another time, it was due to a deformed lower control arm - I hit a pothole without slowing down and bent it, causing wheel misalignment during braking. These issues should be addressed promptly for peace of mind, as brake pulling at high speeds can be particularly dangerous. I recommend regularly checking tire pressure and the braking system, and seeking professional comprehensive inspection at specialized shops when problems arise without delay.
