Introducing the Power Stop S2108 Rear Caliper Set, an exceptional upgrade for your Audi A4's braking system. This caliper set is meticulously engineered to provide superior stopping power, improved pedal feel, and enhanced durability.

The S2108 caliper set features Power Stop's patented high-performance ceramic brake pads.

Installation of the S2108 caliper set is straightforward, with no major modifications required. Each caliper comes with mounting brackets and hardware, ensuring a secure and accurate fit on your Audi A4. Additionally, Power Stop provides detailed installation instructions to guide you through the process.

The PowerStop S2108 Rear Caliper Set is a popular aftermarket brake upgrade option for the Audi A4. Here are some pros and cons to help you make an informed decision:

1. Improved Braking Performance: The PowerStop S2108 Caliper Set comes with high-performance ceramic brake pads that offer better stopping power and improved thermal stability compared to original equipment pads.

2. Enhanced Pedal Feel: The upgraded ceramic pads provide a more responsive and firmer pedal feel, which can lead to more confidence when braking.

3. Longer Brake Pad Life: Ceramic brake pads typically last longer than OEM pads due to their superior heat resistance and wear resistance.

4. Easy Installation: The PowerStop S2108 Caliper Set is designed to be a direct replacement for the stock calipers, making for a relatively straightforward installation process.

5. OEM Fit and Finish: The calipers are engineered to fit and finish like OEM components, ensuring a factory-like appearance.

1. Cost: The PowerStop S2108 Rear Caliper Set is more expensive than OEM calipers and pads.

2. Potential Noise: Some customers have reported that the ceramic pads can produce more noise than OEM pads during normal use. However, this is not a common complaint.

3. Break-In Period: Ceramic pads require a break-in period to allow the surfaces to bed in properly. This can result in increased pedal travel and noise during the first few hundred miles.

The PowerStop S2108 Rear Caliper Set is a worthwhile investment for Audi A4 owners seeking improved braking performance and a more responsive pedal feel. While it comes with a higher price tag, the benefits often outweigh the cost. Any potential noise issues are generally minor and can be mitigated with proper bed-in procedures.

If you're an Audi A4 owner looking to enhance your vehicle's braking performance, the PowerStop S2108 Rear Caliper Set is a solid choice. Just be prepared for the added cost and the potential for a slight increase in noise during the break-in period.
