What causes the squeaking noise when braking at low speed in a Haval H2?
2 Answers
Haval H2 produces a squeaking noise when braking at low speed. This situation is most likely caused by severely worn brake pads, where the warning shim emits a sharp squeaking noise to prompt replacement. Unlike engine oil and filters, brake pad replacement cannot be simply recommended based on mileage. Therefore, the vehicle's braking system has its own warning system to alert the owner to replace the brake pads. More detailed information is as follows: 1. The replacement cycle of brake pads depends on the vehicle's driving conditions, the frequency and force of the driver pressing the brake pedal. Under normal circumstances, the front brake pads wear out faster than the rear ones. The lifespan of front brake pads is approximately 30,000-50,000 kilometers, while the rear brake pads last about 100,000-150,000 kilometers. 2. If the noise persists, first check for any dragging brakes. Poor caliper retraction can cause prolonged friction between the disc and pad, leading to squeaking under certain conditions. Then, check if there are any foreign objects stuck between the pad and disc. For new pads, inspect whether the brake disc has grooves, as localized friction can cause noise. If the disc is fine, consider whether the anti-noise shim was installed incorrectly.
I've been driving a Haval H2 for over three years and often hear abnormal noises when braking at low speeds, which is mostly a minor issue with the braking system. When the brake pads wear thin, their rough edges rubbing against the brake disc can produce a screeching sound. Alternatively, if the brake disc gets contaminated with sand or rust, especially after rainy days, this can also happen. Lack of lubrication in the caliper guide pins causing them to stick can lead to noise during low-speed vibrations. I've noticed that at low speeds, noises are more likely to reveal problems. I recommend first checking the thickness of the brake pads—replace them if they're less than 3 mm—and then gently cleaning any debris from the disc surface with a cloth. Don’t ignore increasing noises or vibrations, as these could lead to brake failure at high speeds, which is very dangerous. Have a mechanic inspect the braking system during annual maintenance; regular upkeep can prevent major failures. Safety always comes first—don’t take risks over minor issues.
