Is Wheel Alignment Necessary When Changing Brake Pads?
2 Answers
Changing brake pads does not require wheel alignment. Here are the relevant details: Wheel Alignment: It refers to measuring and adjusting the alignment angles of all four wheels based on the average thrust direction of the rear wheels as the reference. This ensures that the chassis components and tires maintain proper geometric relationships while driving, allowing the driver to operate their vehicle correctly and comfortably, and extending the service life of tires and related chassis components. Situations requiring wheel alignment include: before the annual vehicle inspection, when a new car has traveled 3,000 kilometers, every six months or when the vehicle has traveled 10,000 kilometers, after replacing or adjusting tires or the suspension system, when replacing the steering system or its components, when the steering wheel is not straight during straight-line driving, when the steering wheel needs to be held tightly during straight-line driving, when the vehicle pulls to one side during straight-line driving, when the steering wheel is too heavy or does not return to center automatically during turns, when the body feels unstable or floats while driving, when there is abnormal tire wear, and after repairing a vehicle involved in an accident.
Last time I went to change the brake pads, the guys said there was absolutely no need for an additional wheel alignment. I've pondered this quite a few times. Changing brake pads is just about removing the tires and replacing the caliper components inside, purely working on the brake system without touching the suspension angles. A wheel alignment requires professional machines to measure and adjust the camber and toe angles of the tires to prevent uneven wear from misalignment. You should only get an alignment check if you really feel the steering wheel is loose or the wheels are pulling to one side. After changing the pads, it's best to take a short test drive yourself—if the brakes feel stable, then everything's fine. Saving money is the name of the game; don't waste it on alignments if there's no issue. I usually pay attention to tire pressure and brake disc health during maintenance. After changing the pads, I just go for a drive, no problems at all—easy and worry-free, plus I get to see more sights along the way.
