Prestige Parts® Gas Springs & Brake Accumulators: Engineering Excellence for Rolls-Royce & Bentley

Brake accumulators are a critical component in a hydraulic braking system. The primary function is to store pressurized brake fluid, serving as an energy reserve. In situations where the primary hydraulic pressure source is inadequate, the accumulator provides the necessary pressure to maintain consistent brake performance, not just as a matter of convenience, but of safety. In vehicles like the Rolls-Royce Silver Seraph and Bentley Arnage, the braking system is particularly nuanced and the accumulators need to ensure optimal braking under diverse driving conditions.

IntroCar's Prestige Parts® range, recognized for its commitment to quality and innovation, now includes Brake Accumulators for the Arnage and Seraph series, engineered to match the OEM specifications providing reliability, longevity and sold with the standard 3 year warranty. 

Prestige Parts® stands apart as an aftermarket solution with unwavering dedication to quality and through its international reseller network, it serves those who prioritize precision and are passionate about sustaining the legacy of Rolls-Royce and Bentley.

Which Parts for Which Model

  • Application: All Rolls-Royce & Bentley models from 1980 to 1998 with chassis 1001 onwards and Bentley Azure 1995-2003.
  • Function: This component is responsible for maintaining hydraulic system pressure even when the engine is off, ensuring 40-50 pumps before brake failure. Accumulator spheres play a pivotal role as a backup during pump malfunctions.
