Why Do Brake Pads Turn Red?

[DelCamila]

Brake pads turning red is caused by frequent braking and poor heat dissipation of the brake pads. Here are some precautions for brake pad replacement: 1. Check thickness: New brake pads are generally about 1.5 cm thick. If worn down to one-third of their original thickness (less than 5 mm), it is recommended to replace them promptly. 2. Listen for sounds: If you hear metallic scraping noises when braking, this may indicate that the brake pads have worn down to their minimum thickness, causing the wear indicators on both sides to rub against the brake disc, producing abnormal sounds. Immediate replacement is needed. 3. Watch for warnings: Some vehicle models have brake wear indicators. If the brake pads are excessively worn, the sensor wire may come into contact with the brake disc, causing a change in resistance and generating an electrical signal detected by the system. A brake pad warning light will then appear on the dashboard. 4. Rely on feel: If the brake pedal feels too light or if braking feels difficult or ineffective, this indicates severe wear and insufficient thickness of the brake pads, requiring immediate replacement.
