Haval H2 Brake Noise at Low Speed

[RonanLee]

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.

A friend who drives a Haval H2 mentioned that there's always a screeching sound when braking, and I've encountered similar issues before. It's mostly due to improper coordination of brake components: uneven distribution of friction material when newly replaced brake pads aren't properly worn in can easily cause abnormal noises; insufficient lubrication of brake caliper guide pins leading to dragging brakes; sometimes it's also caused by burrs on the edges of brake pads scraping against the brake discs. Once I lifted the car and used an endoscope to inspect, finding a small stone stuck in the brake disc dust cover. Recent weather changes also have noticeable effects – brake disc surfaces rust in humid seasons, making the squeaking particularly loud during light braking at low speeds. The solution is actually quite simple: perform several medium-force brakes in succession, as the heat generated by friction can remove surface rust from the discs. If the noise persists after driving 200 kilometers, it's necessary to check the caliper's return condition and clean the guide pins before reapplying grease if needed.

I've had personal experience with the brake noise issue on the Haval H2. The most likely cause is a problem with the brake pads: if the metal particles in the material formula are too large, they can scratch the disc and create noise; if the edges of the pads aren't chamfered, they can interfere with the brake disc and produce high-frequency friction sounds. Another easily overlooked detail is when the brake caliper screws aren't torqued to specification during assembly, causing abnormal vibration in the brake pads. Last time I dealt with this, I cleaned out any sand or debris between the disc and pads, and also smoothed out the sharp edges of the brake pads. I recommend paying attention to the pattern of the noise—if it's loudest during cold starts, it's usually a material issue; if it disappears at slightly higher speeds, it might be due to an uneven disc surface. If you're handling it yourself, be careful not to damage the surface coating of the brake disc.

While driving my friend's Haval H2, I noticed a clunking sound during low-speed braking. I've researched such issues. The key is distinguishing safety concerns: continuous sharp squealing may indicate worn brake pads needing replacement; occasional clicking could just be a small stone lodged in the system. Remember to check that brake pad thickness shouldn't fall below 3mm. Another scenario involves thermal deformation from uneven brake disc temperatures, causing friction tremors during light braking. Pay special attention to the first brake application after rain - temporary noise from surface rust is normal. Regular wheel cleaning minimizes debris ingestion, while occasional hard braking on highways helps self-clean disc surfaces. Persistent noise beyond two weeks warrants comprehensive brake system inspection.

I've dealt with the brake squealing issue on the Haval H2 multiple times, and experience tells me it mostly stems from assembly details. For instance, the brake pads weren't given noise reduction treatment during production, leading to vibration of the backplate causing friction squeals. There's also insufficient lubrication of the caliper sliding pins, resulting in particularly harsh metal-on-metal scraping sounds when the car is cold. The simplest solution is to perform ten consecutive emergency stops from 60km/h, using the high-temperature friction to remove the hardened layer on the brake pad surface. Last time when helping a neighbor, I found the dust shield was slightly deformed and rubbing against the rotor - straightening it fixed the issue. I recommend not parking immediately after car washes; drive a short distance to let the braking system dry completely. Of course, if accompanied by brake pedal vibration, one must consider brake disc warping which requires professional attention.
