The sensor provides pressure information to the vehicle's electronic control systems. This allows the vehicle to monitor whether sufficient vacuum assistance is available for correct brake booster operation.
A faulty sensor can produce incorrect pressure readings, warning messages or diagnostic fault codes and may interfere with the vehicle's ability to accurately monitor the brake assistance system.
What This Product Does:
The brake booster uses vacuum assistance to reduce the amount of pedal effort required from the driver when applying the brakes.
The pressure sensor monitors conditions within the brake booster vacuum circuit and sends an electrical signal representing the measured pressure to the relevant vehicle control system.
This information can be used to:
- Monitor brake booster vacuum
- Confirm that sufficient brake assistance is available
- Detect abnormal pressure conditions
- Support brake-system diagnostics
- Identify problems within the vacuum supply system
- Provide information to relevant electronic control systems
- Trigger warnings or fault codes when an abnormal condition is detected
The sensor therefore acts as an important monitoring component within the brake assistance system.
Symptoms Of Wear Or Failure:
A faulty or deteriorated pressure sensor can provide inaccurate, intermittent or missing signals.
Possible symptoms include:
- Brake-system warning message
- Brake warning light
- Diagnostic trouble codes
- Brake booster pressure or vacuum-related fault codes
- Intermittent warning messages
- Implausible pressure readings during diagnostics
- Missing or unstable sensor data
- Faults that return after being cleared
- Electrical circuit fault codes
- Poor or intermittent connection at the sensor
- Reduced brake assistance if an underlying vacuum-system fault is also present
Because this sensor primarily monitors the system, symptoms such as a hard brake pedal should prompt inspection of the complete brake booster vacuum circuit rather than automatic sensor replacement.
Why Replacement Matters:
If testing confirms that the brake booster pressure sensor is faulty, replacement helps restore accurate monitoring of the brake booster vacuum system.
A correctly functioning sensor can help:
- Restore accurate pressure information
- Restore reliable brake booster vacuum monitoring
- Resolve confirmed sensor-related diagnostic faults
- Eliminate incorrect or intermittent sensor signals
- Restore communication with the vehicle's control system
- Support correct brake-system diagnostics
- Ensure genuine vacuum problems can be identified correctly
Because the sensor is associated with a safety-critical braking system, confirmed faults should be addressed promptly.

This OE Match brake fluid reservoir hose is a replacement hose for Porsche 911, 964, and 993 models. It is designed to match the original-style fitment and function, helping maintain a secure fluid connection between the brake fluid reservoir and the braking system.
Comes as 5m roll / Ø 7mm
Fits:
Porsche 911 1965 - 1989
Porsche 964 1989 - 1994
Porsche 993 1995 - 1998
The brake fluid reservoir hose carries brake fluid from the reservoir to the brake system feed connection. A secure, leak-free hose is essential for maintaining correct brake fluid supply, reducing the risk of fluid loss, and supporting reliable brake hydraulic system operation.
Functions
• Replaces the brake fluid reservoir hose
• Carries brake fluid from the reservoir to the brake system
• Helps maintain a leak-free brake fluid connection
• Supports correct brake hydraulic fluid supply
• Helps prevent brake fluid seepage and contamination
• Replaces aged, cracked, hardened, swollen, or leaking original hoses
• OE Match replacement for brake system repair and restoration.
Why Replace This Part?
Brake fluid reservoir hoses can harden, crack, swell, soften, leak, or deteriorate over time due to age, brake fluid exposure, heat, and previous repairs. A failing hose may cause brake fluid seepage, low fluid levels, brake warning issues, fluid contamination, or damage to nearby painted surfaces. Replacing the hose helps restore safe, reliable brake fluid transfer and supports correct braking system maintenance.
When to Replace This Part
• The hose is cracked, hardened, swollen, soft, brittle, or leaking
• Brake fluid seepage is visible around the reservoir or hose connections
• The brake fluid reservoir has been removed or replaced
• Brake hydraulic system service is being carried out
• The hose is contaminated or showing signs of age-related deterioration
• Brake fluid level drops without another obvious cause
• The car is undergoing Porsche 911, 964, or 993 brake system restoration
Where it fits on the car
This hose fits at the brake fluid reservoir area on Porsche 911, 964, and 993 models. It forms part of the brake fluid feed connection from the reservoir into the brake hydraulic system.
