How to Solve the Brake Noise Issue in Volkswagen Bora?
2 Answers
Brake noise could occur during the "break-in" period of the brake discs, which is actually a normal phenomenon. Below are the causes and solutions for brake noise in the Volkswagen Bora: 1. Continuous heavy braking: The so-called brake fade is essentially a process where excessive use of brakes in a short period causes the brake discs to overheat, thereby reducing braking power. When driving the car with continuous heavy braking, brake fade occurs. Two specific manifestations of brake fade are a noticeable decrease in braking power and the appearance of sharp noises that are not usually heard, referred to as "abnormal noise." Both of these are normal occurrences during brake fade and do not indicate a brake malfunction. 2. Excessive wear of the brake discs: Not only can excessive wear of the brake pads cause "strange noises," but excessive wear of the brake discs can also lead to this issue. When the thickness of the brake discs falls below the critical point, the metal edges surrounding the brake discs will come into direct contact with the brake pads. This not only results in loud abnormal noises but may also cause brake failure, severe body shaking, and other problems. When this happens, it indicates that the brake pads are excessively worn and must be replaced. Failure to replace them will not only make the loud noise unbearable but also lead to a significant decrease in braking power, increasing safety hazards.
I've been repairing cars for over a decade and have seen countless cases of Volkswagen Bora brake squealing. The most common issue is worn-out brake pads, where the hard metal wear indicator starts scraping against the brake disc, producing a sharp metallic grinding sound when you brake. Quickly check if your wheel hub feels hot to the touch. Another frequent cause is newly installed low-quality brake pads containing hard particles - if these don't wear off after a few hundred kilometers, they'll keep squeaking. Rusty brake discs after rain may also cause temporary noise, but this typically disappears after a couple minutes of driving. My advice? Drive straight to the repair shop and have them inspect it on a lift. If you find deep grooves worn into the brake disc, don't hesitate - replace the whole set immediately. Safety should always come first.
