What Is a Hydraulic Load Cell Pedal Set? CPP-Lite Explained

A hydraulic load cell pedal set uses fluid resistance and electronic sensing for realistic sim racing braking. The Conspit CPP-Lite is a prime example.
Quick answer
A hydraulic load cell pedal set combines a fluid-based brake pedal with an electronic load cell sensor to deliver progressive, realistic resistance in sim racing. The Conspit CPP-Lite 3 Pedal Set is a professional example that offers fully adjustable hydraulic feel and precise load cell measurement.
Why hydraulic plus load cell matters
Standard sim racing pedals use springs or rubber bumpers to create resistance, which can feel artificial and lack consistency. A hydraulic system uses fluid pressure to mimic the progressive resistance of a real race car brake pedal, giving you better muscle memory for real-world driving.
The load cell sensor measures the exact force you apply, not just pedal position. This means your inputs are more accurate and repeatable, which is critical for consistent lap times and precise braking zones.
Trade-offs to consider
Hydraulic load cell pedals are more expensive than basic spring-based sets. They also require a bit more setup—you need to bleed the hydraulic system and calibrate the load cell to your preference.
If you only play arcade-style racing games or have a tight budget, a simpler pedal set may be sufficient. But for serious sim racers or those training for real motorsports, the investment pays off in realism and consistency.
Frequently asked questions
- How does a hydraulic load cell pedal differ from a standard sim pedal?
- Standard pedals use springs or elastomers for resistance and measure position. Hydraulic load cell pedals use fluid for resistance and measure force directly, offering a more realistic and consistent brake feel.
- Do I need special software to use the CPP-Lite?
- The CPP-Lite connects via USB and is recognized as a standard USB game controller. Most sim racing titles (iRacing, Assetto Corsa, rFactor 2, etc.) support it without additional drivers. You may need to calibrate the load cell in the sim's control settings for optimal performance. Check your sim's controller setup menu to assign the brake and clutch axes after plugging in.
- Is the hydraulic system maintenance-intensive?
- Hydraulic pedals require occasional bleeding to remove air bubbles, similar to a real car brake system. The CPP-Lite uses a sealed system, so under normal use, bleeding is only needed after initial setup or if you disconnect the hydraulic line. This is a one-time or rare task. Keep the supplied bleeding kit handy for initial setup; after that, expect years of trouble-free use.
Product facts
- Conspit CPP-Lite 3 Pedal Set – Hydraulic Load Cell Sim Racing Pedals: The Conspit CPP-Lite 3 Pedal Set features a 10MPa (~100KG) hydraulic brake pedal with fully adjustable progressive resistance. This means you can dial in the brake feel to match your personal preference or even mimic a specific real car's brake pressure, making your sim practice more transferable to the track.
