Manufactured to Porsche's original specifications, this protective cover forms part of the vehicle's anti-lock braking system installation, helping shield the associated components from dust, dirt, debris and accidental contact.
The ABS system is an important safety feature that helps prevent wheel lock-up during heavy braking, supporting steering control and vehicle stability. Its electrical and hydraulic components require secure installation and appropriate protection to maintain their intended operating environment.
The ABS system cover provides the factory-specified covering for the relevant regulator assembly, helping maintain the original layout and condition of the surrounding installation.
Over time, the original cover may become cracked, damaged, distorted or lost during maintenance, electrical repairs or restoration work. A damaged or missing cover can leave the associated components more exposed to contamination and accidental contact.
Replacing a worn or missing ABS system cover with a Genuine Porsche component helps restore the intended protective arrangement, maintain original equipment fitment and preserve the factory appearance of the ABS installation.
Ideal for Porsche 964 maintenance, ABS system repairs, preventative servicing and classic Porsche restoration projects.
What This Product Does:
The ABS system cover is a protective component within the anti-lock braking system assembly.
Its primary functions include:
- Protects ABS Components: Helps shield the associated ABS regulator or control module area from dust, dirt and debris.
- Provides Physical Protection: Reduces the likelihood of accidental contact with covered components during routine maintenance.
- Maintains Factory Installation: Restores the original protective cover specified for the ABS assembly.
- Supports Component Protection: Helps reduce exposure to loose objects and incidental contact within the installation area.
- Provides Correct Cover Positioning: Designed to fit the intended mounting arrangement without the need for improvised replacement covers.
- Preserves Original Appearance: Maintains the factory-style appearance of the Porsche 964 ABS assembly.
- Supports Long-Term Maintenance: Helps keep the relevant ABS system components appropriately covered and accessible for servicing.
- Maintains Original Equipment Specifications: Replaces the factory component using the specified Porsche part number.
Symptoms Of Wear Or Failure:
Unlike electronic or hydraulic ABS components, the protective cover has no moving parts and does not normally suffer from mechanical wear during operation.
However, ageing, accidental damage, incorrect installation or repeated removal can affect its condition.
Common indications that the ABS system cover may require replacement include:
- Cracked or Split Cover: Visible fractures or splits in the cover material.
- Broken Mounting Points: Damaged attachment points may prevent the cover from fitting securely.
- Loose or Insecure Fitment: The cover may move or fail to remain correctly positioned.
- Missing ABS Cover: The original component may have been removed or lost during previous repairs.
- Deformed or Distorted Shape: Impact, excessive force or unsuitable storage may cause the cover to lose its original shape.
- Brittle or Deteriorated Material: Ageing may make the cover more susceptible to cracking during removal or installation.
- Visible Surface Damage: Scratches, chips or other damage may affect its appearance or protective coverage.
- Difficulty Refitting the Cover: Damaged edges or mounting features may prevent correct engagement.
- Unwanted Rattling: A loose cover may cause vibration-related noise.
- Exposed ABS Components: A missing or damaged cover may leave areas of the ABS installation without their intended protective covering.
Why Replacement Matters:
Replacing a damaged, deteriorated or missing ABS system cover helps maintain the original protective arrangement of the vehicle's anti-lock braking system.
Key Benefits of Replacement:
- Restores Original Component Protection: Replaces damaged or missing covers to help keep the associated ABS components appropriately shielded.
- Helps Reduce Contamination: Provides a barrier against dust, debris and incidental contact within the installation area.
- Maintains Secure Fitment: Restores correct cover positioning where the original component is damaged.
- Protects Against Accidental Contact: Helps prevent unintended contact with covered components during servicing or maintenance.
- Maintains Factory Specifications: Provides the original Porsche component designed for the specified assembly.
- Supports Long-Term Component Care: Helps preserve the intended protective environment of the ABS installation.
- Improves Installation Appearance: Replaces cracked, damaged or missing covers with a factory-style component.
- Ideal for Classic Porsche Restoration: Helps retain original equipment detailing on Porsche 911 (964) vehicles.
- Supports Proper ABS System Maintenance: Allows the protective cover to be renewed without unnecessarily replacing the control module or hydraulic components.
- Genuine Porsche Quality: Offers original equipment specifications and fitment for the relevant application.
- Cost-Effective Replacement: Restores a small but useful protective component without replacing otherwise serviceable ABS parts.
Although the ABS system cover does not directly influence braking pressure or ABS activation, it performs an important protective function within the assembly.
A damaged or missing cover can leave the relevant components more exposed to unwanted contact and debris, while an incorrectly fitted cover may become loose or interfere with neighbouring components.
Replacing the cover helps maintain correct factory installation, original appearance and long-term component protection.

Porsche Hydraulics & ABS Pumps | Precision Braking & Stability Control Performance
Hydraulic systems and ABS pumps are essential to your Porsche’s braking and traction control systems. The ABS (Anti-lock Braking System) pump regulates brake fluid pressure during hard braking, preventing wheel lockup and maintaining grip. Together with hydraulic control units, these components ensure safe, balanced, and responsive braking under all conditions.
At Design911, we supply premium hydraulic units and ABS pumps that meet or exceed original performance specifications. Built from precision-machined materials and designed for exact pressure regulation, our components deliver consistent braking performance, long-term reliability, and improved safety across all Porsche models.
Whether you’re restoring a classic system or servicing a modern Porsche with advanced driver aids, our hydraulic and ABS components ensure stable, dependable performance mile after mile.
What Do Hydraulic Systems & ABS Pumps Do?
Hydraulic units and ABS pumps manage brake pressure and hydraulic flow within the braking system to provide precise control and improved stability.
Core Functions:
- ABS
Pump: Prevents wheel lock by modulating brake pressure during heavy
braking.
