At Meta Mechanics, we recently completed a rear brake pad replacement on an Audi SQ4, and during the inspection, we identified a few issues that needed attention to ensure the vehicle’s braking system performs at its best. Below is a detailed account of the problems we discovered and the solutions we implemented to restore optimal performance and safety.
Issue Identified:
Issue #1: Worn and Thin Rear Brake Pads
- What We Found: The rear brake pads on the Audi SQ4 were found to be worn well below the recommended thickness. Over time, brake pads naturally wear down from regular use, but when they reach an unsafe level, they can dramatically reduce braking efficiency, increase stopping distances, and even cause damage to the rotors.
- Solution: We replaced the old, worn pads with high-quality, OEM-compatible brake pads designed specifically for the Audi SQ4. These new pads will restore the vehicle’s braking power, ensuring a smooth, quiet, and effective braking experience.
Issue #2: Brake Pad Contamination
- What We Found: Upon further inspection, we noticed that the rear brake pads had been contaminated with grease and brake fluid, likely from a previous service or a minor fluid leak. Contaminated pads can lead to poor braking performance, increased noise, and potential damage to the rotors.
- Solution: In addition to replacing the pads, we thoroughly cleaned the brake components and checked for any source of contamination. We ensured that the new pads were free of any contaminants, and we also addressed any potential leaks to avoid recurring issues.
Issue #3: Uneven Brake Pad Wear
- What We Found: The brake pads showed signs of uneven wear, with one side significantly more worn than the other. Uneven wear can be caused by a variety of issues, including a malfunctioning caliper, improperly lubricated components, or even misalignment in the braking system.
- Solution: We conducted a thorough inspection of the calipers and suspension components to identify the cause of the uneven wear. After cleaning, lubricating, and recalibrating the calipers, we ensured that the new brake pads made even contact with the rotors, promoting uniform wear and smoother braking.
Issue #4: Rusted and Scored Brake Rotors
- What We Found: The rear brake rotors showed signs of light rust and scoring, which is common in regions with high humidity or when vehicles are driven infrequently. Rust can cause uneven braking, noise, and can prematurely wear down new brake pads.
- Solution: We resurfaced the rotors to remove the rust and scoring, ensuring a smooth, flat surface for the new brake pads to make proper contact. In cases where rotors are excessively damaged, full rotor replacement may be necessary, but in this case, the rotors were able to be cleaned and restored.
Issue #5: Sticking Brake Calipers
- What We Found: The rear brake calipers on the Audi SQ4 were found to be slightly sticking. This means the caliper was not releasing fully after applying the brakes, causing the pads to remain in contact with the rotor, leading to excessive heat, premature pad wear, and reduced braking efficiency.
- Solution: We cleaned and lubricated the calipers, ensuring that they moved freely and applied even pressure to the new brake pads. By addressing this issue, we eliminated the risk of premature wear and restored smooth, responsive braking performance.
