Frequently Asked Questions
Find answers to common questions about torque specifications
Q1 Are these brakes compatible with all 2007-2011 Subaru Impreza models?
Are these brakes compatible with all 2007-2011 Subaru Impreza models?
These brakes are designed to be compatible with all 2007-2011 Subaru Impreza models, including sedan and hatchback variants. They meet OEM specifications for rotor size, pad dimensions, and caliper fitment. However, it is recommended to verify compatibility with your specific trim level, as performance or AWD models may have unique requirements.
Q2 What is the recommended maintenance schedule for these brakes?
What is the recommended maintenance schedule for these brakes?
Brake pads should be inspected every 12,000 miles or annually, and rotors should be checked for wear and warping. Replace pads when thickness is below 3mm. Brake fluid should be flushed every 30,000 miles or 2 years. Regular cleaning of brake components is advised to prevent debris buildup and ensure optimal performance.
Q3 How do I replace the brake pads on a 2007-2011 Subaru Impreza?
How do I replace the brake pads on a 2007-2011 Subaru Impreza?
1. Lift the vehicle and remove the wheels. 2. Unbolt the caliper and hang it securely. 3. Remove the old brake pads and inspect the rotor. 4. Compress the caliper piston using a C-clamp. 5. Install new pads and reassemble the caliper. 6. Reinstall the wheel and lower the vehicle. Test brakes before driving.
Q4 What should I do if my brakes are squeaking or vibrating?
What should I do if my brakes are squeaking or vibrating?
Squeaking may indicate worn pads or debris on the rotor. Inspect and clean the braking surfaces. Vibrations often suggest warped rotors, which may need resurfacing or replacement. Ensure all components are properly torqued and lubricated. If issues persist, consult a professional mechanic for further diagnosis.
Q5 How can I optimize the performance of my brakes?
How can I optimize the performance of my brakes?
Use high-quality brake pads and rotors designed for your driving style. Regularly clean brake components to prevent contamination. Upgrade to performance brake fluid for better heat resistance. Avoid aggressive braking and allow brakes to cool after heavy use. Properly bed new pads to ensure even wear and optimal performance.
