These pads are designed to reduce brake dust and provide consistent performance under high temperatures.
Q3 How often should the brake fluid be replaced on the Audi S3?
How often should the brake fluid be replaced on the Audi S3?
Audi recommends replacing the brake fluid every 2 years or 30,000 miles, whichever comes first. Use only DOT 4 brake fluid with a minimum boiling point of 446°F (230°C) to ensure proper hydraulic performance and safety.
Q4 What is the recommended brake rotor thickness specification?
What is the recommended brake rotor thickness specification?
The minimum allowable thickness for the front brake rotors is 28 mm, and for the rear rotors, it is 20 mm. Rotors should be measured with a micrometer during service to ensure they meet these specifications. Replacement is required if the thickness falls below these values.
Q5 Can I upgrade the brakes on my Audi S3?
Can I upgrade the brakes on my Audi S3?
Yes, the Audi S3 can be upgraded with performance brake systems such as the Audi Sport or aftermarket options like Brembo or AP Racing. Ensure the upgraded system is compatible with the vehicle's ABS and ESC systems. Always consult a certified Audi technician for installation.
Q6 What is the torque specification for the brake caliper bolts?
What is the torque specification for the brake caliper bolts?
The brake caliper bolts on the Audi S3 should be torqued to 90 Nm (66 lb-ft) for the front calipers and 35 Nm (26 lb-ft) for the rear calipers. Always use a calibrated torque wrench and follow the proper tightening sequence.
