What Causes the Brake Noise in the Boyue?

[McZoe]

The Geely Boyue is a compact SUV launched by Geely Auto, with its body dimensions being 4519mm in length, 1831mm in width, and 1694mm in height, a wheelbase of 2670mm, and a fuel tank capacity of 58 liters. The reasons for brake noise in the Geely Boyue are: 1. Poor lubrication of the shock absorber's top rubber or buffer rubber; 2. Low temperature of brake fluid when the car is cold; 3. Severe wear of the brake pads; 4. Presence of foreign objects on the surface of the brake disc. Solutions for brake noise in the Geely Boyue: 1. Check if there is an issue with the lubrication of the shock absorber's top rubber or buffer rubber; 2. Break in new brake friction pads; 3. Replace the brake pads in time; 4. Clean foreign objects from the surface of the brake disc.

Speaking of brake noise, I encountered it in the third year of driving my Boyue. The front wheels squeaked embarrassingly when starting the car cold, and upon inspection, I found small stones stuck at the edges of the brake pads. The mechanic said the OEM brake pads on the Boyue contain a high amount of metal particles, which are wear-resistant but prone to picking up stones. It's more noticeable on rainy days when rust particles stick to the brake discs, making the first few brake applications sound like nails on a chalkboard. Recently, I did some research and found that grooved brake discs can also cause metallic friction noises. If the noise persists for two weeks, it's advisable to visit the dealership to have the brake pads chamfered and polished, and to check the anti-vibration shims—don't wait until the warranty expires like I did.

My friend's new Boyue Pro had the same issue last time. The dealership claimed it was normal, but upon actual inspection, we found the caliper guide pin grease had dried up. This component affects whether the brake pads can retract smoothly—lack of lubrication causes squeaking. I've also seen new cars where the brake disc anti-rust coating wasn't fully worn off; the noise disappeared after driving about 500 kilometers. Don't panic if you hear brief noises right after washing the car or during rainy seasons, but be cautious if there's a whistling sound during acceleration, as it may indicate excessive brake pad wear. For DIY checks, focus on inspecting the brake discs for obvious scratches and remove any small stones stuck in the tire treads.

After twenty years of car repair, I've found that brake noise issues in the Geely Boyue are mainly concentrated in three areas: the OEM brake pads have high copper content and excessive hardness at low temperatures, causing squealing when rubbing against the brake discs; the brake caliper return springs lack sufficient tension, leading to slight brake drag; the most troublesome issue is brake disc warping. Last week, I handled a 50,000-kilometer Boyue that had steering wheel vibration when braking at 80 km/h. Inspection revealed the front brake discs were out-of-round by 0.15 mm - after resurfacing, all noise and vibration disappeared. For daily driving, try to avoid riding the brakes and don't keep your foot on the brake pedal at traffic lights.

Never ignore metallic scraping sounds from your brakes. Last year when I helped my brother inspect his Boyue, there was a squeaking noise from the right front wheel at low speeds. Upon disassembly, we found uneven wear on the brake pads. The key issue was rusted and stuck guide pins causing one-sided wear – continuing to drive like this could have scored the brake disc. I recommend checking brake disc temperature monthly by touching the wheel hubs after normal driving; if one hub is significantly hotter, it usually indicates a caliper issue. When replacing brake pads, supervise the mechanic to clean the guide pins thoroughly – applying specialized copper-based grease works better than anything else.

When encountering brake noise, do three things first: sprinkle some water on the brake disc on a sunny day to listen for sound changes and determine if it's caused by oil contamination; check if there are stones embedded in the tire tread; use a flashlight to inspect the brake pads to see if their thickness is below 3mm. Last week at the repair shop, I saw a Geely Boyue where a thumping sound from the rear turned out to be gravel in the rear brake drum. In fact, many so-called noises are due to increased gaps between the brake pads and calipers, causing metal parts to knock against each other on bumpy roads. Remember, persistent high-pitched squealing must be addressed, especially if accompanied by a soft brake pedal, as it is even more dangerous.
