Reasons for Abnormal Noise in Tesla Brake Pedal?
2 Answers
Because it is in a brand-new state and has not yet been broken in, abnormal noise may occur. Additional information: Foreign objects on the brake pads: When the brake disc forms high temperatures during braking and encounters water, it can cause the brake disc to undergo instant "quenching," forming hard spots on the surface and reducing toughness. During braking, the quenched metal from the brake disc enters the brake pads, causing abnormal noise. Although the quenched metal entering the brake pads does not affect braking performance, it can lead to abnormal wear on the brake disc and generate abnormal noise. Poor brake caliper retraction: The main cause of uneven wear is due to rust or sticking of the caliper, resulting in insufficient lubrication of the guide pins and poor retraction. This causes incomplete contact between the brake pads and the brake disc, leading to uneven wear, abnormal noise, and reduced braking performance, thereby shortening the lifespan of the brake pads. Solution: Inspect the brake caliper and the retraction condition of the guide pins; check the movement of the brake pads within the bracket; perform a deep maintenance of the braking system and replace the brake pads.
After driving my Tesla Model 3 for half a year, the brake pedal occasionally made a creaking sound. At first, I thought it was a minor issue and ignored it. Later, upon inspection, I found out that the brake pads were slightly unevenly worn, and it could also be due to excessive friction caused by accumulated dust or moisture. Tesla's regenerative braking feature means the mechanical brakes are used less, making them particularly prone to rust during long periods of parking or in rainy weather, turning the noise into a reminder. I remember when I went to the service center, they cleaned the brake discs and lubricated the pedal mechanism, which solved the problem. For daily maintenance, it's advisable to pay attention to the pedal feel. If the noise persists, take it to a professional shop immediately—don’t wait too long like I did, ending up spending more on repairs. Safety first—electric vehicle braking systems are complex, and occasional misalignment between regenerative and mechanical braking is common, as noted in feedback from other owners.
