Haval H2 Brake Noise at Low Speed
2 Answers
Haval H2 produces abnormal noise when braking at low speed. This situation is likely caused by severely worn brake pads, where the warning tab emits a sharp abnormal sound to prompt replacement. Steps for replacing car brake pads: 1. Open the engine compartment and check if the brake fluid level is at the normal position to avoid overflow during the replacement process. 2. Use a jack to align with the support points under the car, raise it until the tire completely leaves the ground, then remove the tire. 3. Use a wrench with a socket to remove the bolts of the brake caliper and directly take off the brake pads. 4. Push the brake piston back to its original position and install the new brake pads. 5. After installation, check the brake fluid level. Press the brake pedal firmly several times and then add brake fluid again to ensure the level is at 'max'.
Recently, my Haval H2 has been making squeaking noises when braking at low speeds, and I've been pondering this issue for quite some time. It's particularly noticeable at low speeds, right? It's mainly a problem between the brake pads and brake discs. When the brake pads wear down to their limit, the metal warning tabs rubbing against the disc will screech, and in this case, you must replace the pads immediately. If the surface of the brake disc is scratched or grooved, the friction can be as unpleasant as nails on a chalkboard. Last time I took it apart myself, I found that the caliper slide pins had rusted and seized, causing the brake pads to not retract properly. Also, the noise tends to be more pronounced after washing the car or during rainy, humid weather, as if it's complaining to you. I recommend first measuring the thickness of the brake pads; if there's less than 3 mm left, replace them without hesitation. Also, clean the moving parts of the caliper and apply special lubricant for good results. If the problem persists, you'll really need to check the flatness of the brake discs.
