What Causes the Brake Noise in Volkswagen Tayron?
2 Answers
The reasons for brake noise in Volkswagen Tayron: 1. Check if the parking brake mechanism of the rear wheel caliper is stuck, causing dragging; 2. The brake pads are too hard, resulting in noise, or the brake pads and brake disc are not properly fitted, which usually occurs with newly replaced brake pads; 3. Perform maintenance on the brake caliper to see if the guide pins are stuck or the piston of the wheel cylinder is stuck; 4. The brake disc is uneven and needs to be replaced or removed. There is a product called a brake silencer kit that can be used, applied to the back of the brake pads, which is essentially a high-temperature-resistant grease that can adhere the brake pads to the caliper to prevent vibration. The Tayron is a mid-size SUV with a body structure of 5 doors and 5 seats, dimensions of 4589mm, 1860mm, and 1660mm, a wheelbase of 2731mm, and a suspension system that combines MacPherson strut independent suspension and multi-link independent suspension.
My Tayron started to have brake noise just one year after purchase, especially noticeable after rainy days. Later when chatting with the experienced mechanic at the repair shop, he took off the wheel and showed me the rust on the edge of the brake disc - the friction between the rust particles and brake pads caused that screeching sound. Another possible reason is hard spots in the brake pads, meaning there are particularly hard metal particles embedded in the pads. Here's an interesting fact: VW's OEM brake pads contain high metal content which tends to be noisy, many people switch to ceramic pads to eliminate the noise. I remember that time right after car wash when starting the car, the squeaking sound echoed throughout the entire parking garage, even made neighbors poke their heads out to look.
