The short answer is that brake prices vary by model year, part choice, and where you buy them. For a typical Audi S4, brake pads usually run about $60–$150 per axle, front rotors around $120–$230 each, rear rotors around $100–$180 each, and a full brake job (pads and rotors on both axles, including labor) generally falls in the $300–$700 per axle range. Carbon-ceramic upgrades push the price into the several-thousand-dollar range.
Brake prices depend on model year, region, and whether you use OEM (dealer) parts or aftermarket equivalents. This article outlines current ranges for common components and explains what can lift or lower costs across the S4 lineup, from older generations to newer ones.
Costs by component
The following ranges reflect typical US-market pricing seen from retailers and shops for common components on Audi S4 models (as of the mid-2020s). They are intended as a guide and can vary by year, trim, and supplier.
- Front brake pads (set, OEM or equivalent): $60–$150 per axle
- Front brake rotors (each): $120–$230
- Rear brake pads (set, OEM): $60–$150 per axle
- Rear brake rotors (each): $100–$180
- Front brake calipers (each, new): $250–$600
- Rear brake calipers (each, new): $150–$350
- Brake fluid service: $50–$100
- Labor for replacing pads and rotors (per axle): $150–$300
Prices above are indicative ranges for common maintenance. Individual quotes can be higher in areas with steep labor rates or for days when parts are in short supply.
OEM vs aftermarket and upgrade options
Before the second list, note that choosing aftermarket parts or a factory upgrade can significantly alter total costs. High-performance or carbon-ceramic options, in particular, carry a premium and may require specialist installation.
- Aftermarket pads (front, per axle): $40–$120
- Aftermarket rotors (each): $60–$140
- Aftermarket calipers (each, new): $100–$350
- Full aftermarket brake kit (pads + rotors per axle): $200–$500
- Carbon-ceramic brakes (front + rear upgrade, installed): $8,000–$12,000+
- Labor for aftermarket components (per axle): $100–$300
As a rule, OEM parts tend to carry higher reliability guarantees and may come with dealer-supported warranties, while aftermarket options can offer cost savings or performance tweaks. Carbon-ceramic setups deliver substantial weight and fade resistance but at a substantial upfront price and typically higher maintenance costs when rotors or sensors need replacement.
Year, trim and regional differences
The Audi S4 has evolved through several generations (for example, early B7, then B8/B8.5, and the newer B9 platform). Each generation uses different brake hardware and optional equipment. Carbon-ceramic brakes have been offered as a high-end option on some trims and model years, and regional pricing can vary due to taxes, shipping, and local labor rates. If you’re shopping, it’s wise to obtain quotes for the specific year and trim, and to verify whether prices reflect genuine OEM parts or approved aftermarket equivalents.
Summary
Brake costs for the Audi S4 span a broad range depending on what you replace and whether you choose OEM or aftermarket components. Typical costs to replace pads, rotors, and related hardware on one axle hover in the low hundreds of dollars for pads and rotors, with labor bringing the per-axle total into the mid-range. Upgrades to carbon-ceramic brakes or high-end aftermarket kits can push total project prices into the thousands. Always get multiple quotes, confirm part numbers for your exact model/year, and consider whether a full rotor/pad replacement or a targeted pad-only service best fits your needs and budget.
