What Causes the Squeaking Noise in Bora Car Brakes?

[DelSadie]

Bora car brakes produce squeaking noise due to the following reasons: 1. Presence of sand or other foreign objects between the brake pads and brake discs; 2. Poor quality of brake pad material; 3. Severe wear of brake pads; 4. Brake pads being too hard. Brake pads are consumable parts that gradually thin out with use. When the wear layer is completely depleted, an alarm device on the edge of the brake pad alerts the owner to replace them. The Bora is a compact family sedan under FAW-Volkswagen, with dimensions of 4523mm in length, 1775mm in width, and 1467mm in height, and a wheelbase of 2610mm. In terms of power, the Bora Sport version is equipped with a 1.4T engine paired with a 7-speed DSG dual-clutch automatic transmission, delivering a maximum output power of 96 kW.

I've been repairing Volkswagen cars for over a decade, and there are typically three common causes for brake noise in the Bora. Newly installed brake pads may squeak for a few days, which is normal during the break-in period. When the brake pads are nearly worn out, the warning metal piece scraping against the brake disc will produce a sharp screech, indicating an immediate need for replacement. Additionally, after rain, rust on the brake discs can cause noticeable creaking sounds during the first few starts the next day, which usually disappear after driving a couple of kilometers. Another issue is small stones getting stuck, leading to a clunking noise—this can often be resolved by using a high-pressure water jet to clean the inner side of the wheel hub. I recommend having the mechanic check the brake pad thickness during every maintenance service to avoid last-minute surprises.

Last month, my Bora's brakes made a sharp squealing noise when cold. I took it to the repair shop for inspection. The mechanic found uneven wear on the brake pads, with the left side 2mm thinner than the right. He explained this was due to lack of lubrication on the brake caliper guide pins, causing improper retraction and long-term uneven pressure. The solution was cleaning the guide pins, applying new grease, and replacing all brake pads. After two months of driving, the noise hasn't returned. Fellow car owners, don't delay with similar issues - early repairs save money.

There are several reasons why the brakes of a Bora may make noise. After rainy days, the surface of the brake discs may rust, but the noise disappears after a few presses. If small stones get stuck in the brake pads, they can produce a clicking sound. In winter, low temperatures can harden the brake pads, causing noise during the initial few presses. A squeaking sound when turning may indicate a deformed brake pad shield. The most troublesome issue is warped brake discs, which can cause the steering wheel to shake during high-speed braking. Mechanics usually recommend resurfacing the discs, but if the grooves exceed 1 millimeter, the discs need to be replaced.

I've found that the abnormal noise from the Bora's brakes is related to driving habits. My younger cousin always prefers sudden braking, and his car's brake discs developed grooves before even reaching 20,000 kilometers. From my experience, shifting to neutral at traffic lights can reduce brake pressure. Also, avoid directly spraying the brake discs with a water gun during car washes, as hot brake discs can easily warp when suddenly cooled by cold water. Recently, I switched to a set of ceramic brake pads, which are a bit more expensive than the original ones, but the abnormal noise has indeed decreased significantly. I recommend avoiding cheap brake pads from roadside shops, as their quality is not guaranteed.

I've figured out a few key points about brake noise. After installing new brake pads, it takes at least 200 kilometers of driving for them to quiet down. During inspections, pay special attention to the edges of the brake discs - if there's a raised lip, it means the pads need replacing. For those who've modified their wheels, be aware that certain thick spacers can cause brake pad misalignment. Last time with my car, slow retraction of the caliper pistons caused brake drag, turning the discs blue from overheating. Such situations require immediate attention to avoid damaging the brake calipers. Also, a reminder to all: Volkswagen Bora owners with auto-hold should deactivate the function before entering car washes to prevent thermal shock from cold water on hot discs.
