Common Issues with the Volvo Xc90 Brake Pad Set
Using friction to convert kinetic energy into thermal energy, the Volvo Xc90 brake pad set is built to help stop your car even at highway speeds. Basically, brake pads are steel backing plates with friction material bound at their surface. When you step on the brakes, these pads squeeze together into the brake rotor to generate heat and friction, which helps stop or slow down your car. Although brake pad set are made from high-quality materials, they are also prone to wear and tear. Worn-out brake pads can damage your brake disc, and it won't be able to generate enough friction to stop your car. If you're experiencing reduced braking power, it's time to do some troubleshooting. Here are some common brake pad set issues, and the factors behind them:
Brake pad sets are designed with porous outer coverings for a better rotor grip. If you notice that your car's brake begins to slide or the grip is a bit loose, it could be due to glazed brake pads. Glazed pads are usually shiny and smooth, losing their porous surface. Improper pad bedding and harsh braking increase the rotor's temperature, which cooks the brake pad, causing them to glaze. Check your brake pad set for signs of glazing and replace the glazed pads immediately.
If your brake pad set shows partial charring on its friction material or white outer edges, it's a sign of denatured pads. Denaturing occurs when the brake pad set is exposed to prolonged excessive temperatures, a faulty brake caliper, or intensive use. Over time, the brake pads will become brittle and break up eventually. Inspect your brake calipers to see if they're working properly. Cracked or denatured brake pads need to be replaced to resolve the issue.
Contaminated pad surface
When you notice that your car tends to pull to one side while braking, it could be caused by a contaminated brake pad set surface. Brake fluid, oil, and grease can contaminate the brake pad's surface, affecting its braking performance. Always check your brake rotors for any sign of leaks. Replace worn-out brake hoses and oil gasket to resolve the leaking problem. For contaminated brake pad surfaces, change them with a brand new set of pads.
