The set contains the additional parts that are required for installing the balance beam brake system in the vehicle.
Fits:
Porsche 911 - 1965 to 1977
Porsche 911 - 1978 to 1989 if brake booster (servo) is deleted
Porsche 914 - 1970 to 1976
With brake beam brake pedal installation
Kit Contains:
• Brake fluid reservoirs with clamps x 2
• Connecting hoses between the reservoir and master brake cylinder with suitable clamps
• Connections on the master brake cylinder on the inlet side,
• Adapter to M10x1 thread for the brake light switch
• Pressure-switching brake light switch
• Distribution piece for the front brake circuit (if necessary, the switch can be installed at this point)
• Copper sealing rings x 4
With the standard pedals, the brake light switch is actuated mechanically by the brake pedal, which is no longer possible with the balance arm brake system.
This necessitates hydraulic actuation, which is easily integrated into the brake line using a connector and a pressure-triggering brake light switch.

Manufactured to OEM specifications, this seal ensures reliable performance and is an essential component for maintaining proper brake system function, especially on classic and air-cooled Porsche models.
Key Features
• Direct replacement brake fluid reservoir cap seal
• Fits inside reservoir cap for secure sealing
• OEM-style fit and performance
• Helps prevent brake fluid leaks and contamination
• Durable material for long-term reliability
• Ideal for maintenance and restoration
Function and Purpose
This cap seal ensures a tight closure of the brake fluid reservoir.
It helps to:
• Prevent brake fluid leakage
• Protect system from moisture ingress
• Maintain correct hydraulic pressure
• Preserve braking system performance
Why Replace Your Brake Fluid Cap Seal
Over time, seals can degrade due to exposure to brake fluid and environmental conditions.
Common issues include:
• Cracked or hardened rubber
• Fluid seepage around the cap
• Moisture entering the system
• Reduced braking performance
Replacing the seal helps maintain safe and reliable braking.

OEMatch Brake Fluid Reservoir — Stopping Power, Consistent Control
A replacement brake fluid reservoir for Porsche models, responsible for storing and supplying hydraulic fluid to the master cylinder while protecting the braking system from contamination and moisture. OEMatch supplies a wide selection chosen for Porsche applications to support repair, restoration and routine maintenance.
Available Types
- Replacements suited to classic and modern Porsche models
- Reservoirs offered with integrated fluid-level sensor where specified
- Assemblies supplied with cap and sealing components
Understanding OEMatch Brake Fluid Reservoir
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original brake fluid reservoir. OE (Original Equipment) refers to parts matching original specifications for the brake fluid reservoir and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM brake fluid reservoir engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models. The reservoir stores brake fluid, feeds the master cylinder and helps maintain consistent hydraulic pressure while keeping air and contaminants out of the system. A sound reservoir and secure seals support predictable pedal feel and reduce the risk of fluid ingress or loss.
Benefits Include
- Maintains hydraulic pressure and consistent brake response
- Protects brake fluid from moisture and contaminants
- Facilitates easy visual checks of fluid level and condition
Why Brake Fluid Reservoir Wear and Fail
- Plastic fatigue, cracking or crazing from heat and vibration
- Degrading seals or damaged connections at the master cylinder
- Contamination from moisture or debris entering the reservoir
The Importance of Replacing with OEMatch Brake Fluid Reservoir
Replacing a worn or damaged reservoir restores hydraulic integrity and helps ensure the braking system functions reliably. Correct replacement reduces the chance of fluid loss, air ingress and degraded pedal response, supporting safe operation and consistent braking behaviour across different driving conditions.
Advantages
- Designed for compatibility with Porsche master cylinder assemblies
- Constructed from materials chosen for heat and fluid resistance
- Simplifies servicing with familiar mounting points and sealed caps
Support & Advice
These items affect safety-critical systems. Installation should be carried out by a qualified technician following model-specific procedures and torque settings. Use calibrated tools and new fasteners where specified.
