How to Solve the Brake Noise Issue of Zotye SR9?
3 Answers
If the brake noise of Zotye SR9 persists, the first step is to check for any dragging brakes. Poor caliper reset can cause prolonged friction between the disc and the pad, leading to noise under certain conditions. Also, check for any foreign objects stuck between the pad and the disc. Below are the solutions for the brake noise issue of Zotye SR9: 1. The majority of brake noises come from the brake pads, accounting for over 80% of cases. The noise is usually caused by the scraping sound from worn-out brake pads. Solution: Simply replace the brake pads. 2. Another cause could be the aging surface or sharp edges of the brake pads. Solution: Grinding the surface and edges of the brake pads can resolve the issue. 3. About 10% of brake noises are caused by issues with the brake disc, often due to disc deformation, which leads to uneven contact with the brake pads during driving, resulting in noise. Solution: This can be fixed by performing out-of-round repair and grinding of the disc and pads.
I used to drive a Zotye SR9, and brake squealing might seem like a minor issue but shouldn't be ignored. The most common cause is worn-out brake pads grinding against the wear indicators, producing an annoying squeaking sound. Alternatively, dust or rust residue on the brake rotors—especially after rain—can cause noise, though it usually clears after a few brake applications. Persistent noise may indicate warped rotors, as uneven wear leads to squealing. New cars may also squeak during the break-in period, but this typically fades after a few hundred kilometers. Never ignore it, as severely worn rotors can lead to costly repairs (over a thousand yuan). Aggressive driving habits, like frequent hard braking, accelerate pad wear and increase noise. For safety, I always recommend a full inspection at a 4S shop—using professional tools to measure pad thickness and rotor flatness, while also checking brake fluid levels and caliper condition. Regular maintenance saves both hassle and money in the long run.
The braking system is actually quite sophisticated, and abnormal noises mostly stem from poor coordination between components. For instance, uneven material in the brake pads can cause friction points to squeal against the rotor surface. Alternatively, scratches on the brake disc may require resurfacing. For the Zotye SR9, you can check if the brake disc is excessively hot to determine if debris is stuck, and measure the remaining thickness of the brake pads—replace them if it's below 3mm. Don’t overlook the caliper springs either; if they don’t retract smoothly, they can cause dragging noises. Solutions are straightforward: apply anti-squeal paste during pad installation and opt for OEM-matched parts to prevent issues. Clean the wheel hub area after driving in the rain to reduce rust buildup. New components may need a break-in period—a few hundred kilometers of driving can alleviate normal noises. Overall, prioritize material quality over cheap alternatives. Regular professional inspections are advisable to prevent major failures.
