There are many reasons for brake noise in Geely New Emgrand, such as: 1. Brake pads being too hard; 2. Fixed framework left by worn brake pads; 3. Excessive wear of brake discs or hubs; 4. Rusty brake cylinders; 5. Ineffective manual brake lines; 6. Slow return of the master cylinder, etc. Possible conditions and solutions include: 1. If there is a screeching noise, first check whether the brake pads are nearly worn out (alarm sounds). If they are new, check for foreign objects between the brake disc and pads. 2. If it’s a dull sound, it’s mostly an issue with the brake caliper, such as worn guide pins or detached spring clips. 3. If it’s a faint rubbing sound, it could be an issue with the caliper, brake disc, or brake pads. If the noise persists, first check for braking resistance. Poor caliper reset can cause prolonged friction between the brake discs, leading to abnormal noise. Then check for foreign objects between the discs. If the pads are new, check for grooves in the brake disc, as localized friction can cause abnormal noise. If the brake disc is fine, consider whether the brake linings are too hard or if the muffler is incorrectly installed.
