Why does the Audi's right front wheel make noise when braking?
3 Answers
Audi's right front wheel making noise when braking may be due to the power steering belt of the left front wheel; replacing the belt could solve the issue. Another possible cause of noise could be the brake pads or a deformed metal piece behind the brake disc rubbing against it. Other reasons: There are many reasons for front wheel noise, such as rhythmic sharp sounds, which might be caused by the brake pads being too close to the brake disc, creating friction. Continuous sharp sounds could indicate bearing damage, while continuous dull sounds might suggest a problem with the drive shaft. Normal phenomenon: Some noises do not affect driving but are merely uncomfortable to hear, such as interior rattles, which are usually caused by loose panels rubbing against each other.
I've been driving my Audi A6 for almost three years now, and recently the right front wheel has been making a sharp squeaking noise when I brake. At first, I didn't pay much attention, but the sound has become more frequent, especially on rainy days or during cold starts. After doing some research, it could be that the brake pads have worn down to their limit, triggering the metal wear indicator; or there might be scratches or rust on the brake disc; it could also be small stones or dust stuck between the pads and disc. Last time I went to the 4S shop for a check, they replaced the brake pads, which solved the problem, costing about 800 yuan. I recommend not delaying—Audi's braking system is precise, and small issues left unattended can lead to major failures, such as brake disc warping or caliper seizure. Avoid sudden braking in daily driving and regularly wash the car to clean the wheel hubs, which can extend the lifespan of the parts. Safe driving is key, so take action when you notice a problem.
Having dealt with numerous car issues, common causes of brake noise from the right front wheel of an Audi include excessively worn brake pads—when thickness falls below 3mm, a warning sound is triggered; uneven or grooved brake disc surfaces causing abnormal friction; poor retraction of the brake caliper leading to dragging; or aging brake pad materials. It's advisable to first inspect yourself: remove the wheel to check pad thickness and disc surface smoothness. If the disc is damaged, resurfacing or replacement is needed; caliper issues require lubrication or adjustment. Certain Audi models like the Q5 have had recalls due to caliper design defects, so it's best to check the vehicle's service records. Prompt repairs can prevent more expensive damage to discs and pads, potentially costing over a thousand. Don’t ignore the noise—it’s a warning signal that affects braking performance.
