What to do if the Skoda Superb makes abnormal noise when starting and braking?
4 Answers
Reasons for abnormal noise when braking in the Skoda Superb are as follows: 1. New car break-in or brake pad replacement causing abnormal noise from the brake disc. New cars or newly replaced brake pads may produce abnormal noise during the break-in period. 2. Normal signal of ABS system activation. During emergency braking, the brake pedal may exhibit a bouncing sensation. 3. Severe brake pad wear triggering an alarm. Severe wear of brake pads can cause abnormal braking noise. 4. Severe brake disc wear. Severe wear of the brake disc can form deep grooves on the disc, and friction between the brake disc and the edges of these grooves can produce abnormal noise. 5. Presence of foreign objects between the brake disc and brake pad, leading to abnormal noise.
My Superb has been making a squeaking noise when I brake during startup recently, which is quite annoying. As a long-time owner, I suspect it's mostly due to issues with the brake pads or discs. When the brake pads wear thin, the metal indicator contacts the disc and makes noise, or if the brake discs rust after rain, friction during startup causes sound. That time, I checked it myself—lightly pulled the wheel to inspect the brake pad thickness and replaced the pads directly if they were too thin, saving some money. If the noise is sharp and persistent, it might be due to lack of lubrication on the caliper guides, and applying some specialized grease often solves the problem. Remember to wash the car regularly to rinse out debris inside the wheel arches, as trapped stones can also cause noise. Don’t delay in such cases—address it early to avoid safety risks. I usually open the engine bay monthly for a quick check of the brake fluid level to ensure everything is normal.
In years of auto repair experience, brake noise is quite common, especially when the car starts moving. The Superb model is prone to rust buildup on calipers or brake discs, causing friction sounds. Other possible causes include excessively worn brake pads or foreign objects stuck to them. I recommend owners first identify the noise type: high-pitched squealing may indicate thin pads or wear indicators scraping the disc; low grinding could mean debris lodged in. For DIY inspection, use a flashlight to check pad thickness through the wheel - replace if under 3mm. Cleaning disc surfaces with alcohol to remove rust may help, otherwise professional caliper guide pin lubrication and adjustment is needed. Brake noise shouldn't be ignored - prompt repair prevents potential brake failure.
The strange noise when starting the Octavia is really annoying. As a young person, my first choice is to record the issue and then find a solution using an APP. Download a car repair APP to record the sound type for expert analysis, with most recommendations suggesting to check if the brake system lacks maintenance. The squeaking sound when starting and braking is often due to brake disc rust or pad aging. I'm used to going to a quick repair shop for regular rapid inspections—they can handle pad replacement and lubrication in 30 minutes after scanning with a diagnostic tool. If the budget is tight, you can buy a well-reviewed brake kit online and install it yourself, but for beginners, it's safer to go to a professional shop.
