Pressure accumulator
This original Porsche pressure accumulator, also known as a pressure unit, forms part of the hydraulic brake / ABS control system and helps store hydraulic pressure for correct system operation.

Fits:
Porsche 964 C4 / RS
Porsche 964 Turbo Look C2 / C4

Diagram ref no 24

This component is used within the Porsche 964 hydraulic brake / ABS control system on selected Carrera 4, RS and Turbo Look applications.

What This Part Does / Functions
•  Stores hydraulic pressure within the brake / ABS system
•  Helps support correct hydraulic system operation
•  Assists pressure availability for the anti-lock braking system
•  Works with the hydraulic unit and associated control components
•  Helps maintain consistent braking system response
•  Replaces a weak, faulty or leaking pressure accumulator
•  Provides correct OE Porsche fitment and hydraulic specification
•  Supports proper operation of the factory brake hydraulic system.

Why Replace This Part?
The pressure accumulator is a hydraulic component that can weaken or fail over time due to age, internal diaphragm wear, pressure cycling or fluid system contamination. A failing accumulator may not store pressure correctly, which can affect brake system operation and ABS hydraulic response. Replacing it with an OE Genuine Porsche pressure accumulator helps restore correct hydraulic pressure storage and supports reliable brake system function.

Common Symptoms of a Faulty Pressure Accumulator
•   ABS or brake system warning light
•   Brake hydraulic pressure faults
•   Pump running too frequently
•   Hard or inconsistent brake pedal feel
•   Reduced hydraulic pressure reserve
•   Brake system fault codes
•   Hydraulic fluid leakage around the accumulator area
•   Fault confirmed during brake hydraulic system diagnosis.

When to Replace This Part
•   If hydraulic pressure storage is weak or inconsistent
•   If the brake / ABS pump cycles excessively
•   If brake or ABS warnings are present.
•   If the pressure accumulator is leaking or damaged
•   During hydraulic unit or ABS system repair
•   During brake system overhaul or restoration
•   If the accumulator fails pressure testing
•   When restoring the braking system with OE Genuine Porsche parts.

Where It Fits on the Car
This pressure accumulator fits within the hydraulic brake / ABS control system. It is associated with the hydraulic unit / anti-lock brake system control assembly on the Porsche 964.

Correct installation and brake hydraulic system procedures should always be followed. Brake hydraulic components are safety-critical and should be fitted by a qualified technician.
