What Causes the Unusual Noise When Braking in a Bora?
4 Answers
Reasons for unusual noise when braking in a Bora: 1. The brake discs or pads may have rust or hard spots causing the noise, which usually occurs when the vehicle first starts moving and improves after a few brake applications; 2. The suspension system or pressure bearings may produce noise due to cold weather hardening the rubber components, leading to noise when braking under force, which improves after the car warms up; 3. A faulty brake caliper. The braking performance of a car is determined by the brake pads, so it's essential to maintain them properly. When the brake pads wear down to a certain extent, they need to be replaced promptly. Under normal urban driving conditions, the lifespan of brake pads is approximately 30,000 kilometers.
As a veteran driver who's been driving my Volkswagen Bora for over a decade, I've learned through experience that there are multiple reasons for those squeaky brake sounds. The most common causes are either worn-out brake pads rubbing against the rotor, or dust/rust accumulation on the disc surface especially during rainy days. When I first got the car, I ignored these sounds as minor issues - until it nearly caused an accident. Now whenever I hear squeaking, I personally check pad thickness and clean the rotor surface. If the noise persists, it's time for pad replacement - never compromise safety to save money. Parking in dry areas helps prevent rust formation. While the Bora is reliable, its braking system requires regular maintenance. My experience proves that addressing issues early saves trouble.
As a car enthusiast, I've disassembled the Bora's braking system and found that most brake squealing noises are caused by hard brake pad materials, running-in period sounds, or foreign objects like sand particles on the disc surface. I once helped a friend inspect theirs, and the noise disappeared after cleaning the caliper dust. Rainwater or dust accumulation can easily worsen the problem, making maintenance crucial: regularly replace pads and check disc surface smoothness. Before long trips, it's advisable to pump the brakes a few times to warm them up, reducing cold-start squealing. Don't procrastinate and ignore it, otherwise disc wear will deepen, making repairs costly.
Recently, I was startled by a strange noise when braking my Bora. After checking, it might be due to worn-out brake pads or rust on the discs caused by water. I noticed it was particularly obvious right after the rain, so I need to visit a repair shop ASAP. A friend's car had a similar issue before, and delaying the fix led to louder noises and even affected braking distance, which is quite dangerous. A simple self-check on pad thickness or cleaning the disc surface might help. Usually, avoiding muddy roads can reduce potential noise sources.
