I have a stock '05 Elise and recenty, the brakes are making a scraping sound after i release the brake pedal. Sounds like it's coming from the front, I don't know if it's from the left rotor, or the right, or both. It seems like the brake caliper isn't fully releasing after I let off the brake, or is it simply that my brake pads are worn, and I need to replace them? The car runs fine, and brakes fine. When I accelerate after a stoplight or stop sign, I hear the brakes scraping and as I go faster, the noise goes away. I have performed minor maintenance on cars before, but never worked on any brakes or braking system. I want to get some suggestions before I take the wheels off and look. Do you think I need to bleed out the brake fluid? Or other suggestions? Thank you all.
