Brake Master Cylinder 17,05mm. Porsche 914-4 - 91435501200
91435501200/1
Vehicle Group
- Porsche 914 (1970-1976)
Information
Brake Master Cylinder,
Ø 17,05mm
This OE match brake master cylinder is a direct replacement for the original Porsche component fitted to 914-4 models produced between 1970 and 1976. Manufactured to factory specifications, it features a 17.05mm bore diameter, ensuring the correct hydraulic pressure and pedal feel for the original braking system.
Fits:
Porsche 914-4 1970 - 1976
Diagram ref no
The brake master cylinder converts mechanical pedal movement into hydraulic pressure, allowing brake fluid to activate the brake calipers. It ensures consistent braking force distribution for safe and controlled stopping performance.
Function
• Converts brake pedal force into hydraulic pressure
• Distributes brake fluid to brake calipers
• Maintains consistent braking response and pedal feel
• Supports safe and controlled stopping performance
• Operates as the central hydraulic component of the braking system
Brake master cylinders wear internally over time due to seal deterioration, moisture contamination, and repeated hydraulic pressure cycles. A failing master cylinder can lead to poor braking performance, fluid leaks, or loss of pedal pressure. Replacing it restores safe braking operation, proper hydraulic pressure, and reliable pedal feel.
When to replace
• Soft or spongy brake pedal
• Brake fluid leakage around master cylinder
• Reduced braking efficiency or inconsistent pedal feel
• Internal seal failure causing pressure loss
• During complete brake system restoration or overhaul

Information
Brake master cylinder fluid bottle with lid.
Brake master cylinder reservoir (also known as a brake fluid reservoir with cap), manufactured to match original equipment specifications for classic Porsche vehicles. This reservoir holds and supplies brake fluid to the master cylinder, facilitating proper hydraulic pressure within the brake system and ensuring safe, effective braking performance.
Fits:
Porsche 911 1968
Porsche 911 1974 - 1986
Porsche 911 (930) 1975 - 1977
Porsche 914 1970 - 1976 (914-1.8/1.8V ; 914-2.0)
Diagram ref no 1.
The brake fluid reservoir sits atop the master cylinder and holds the hydraulic brake fluid needed for your vehicle’s braking system. As brake fluid levels drop during use, the reservoir compensates, ensuring uninterrupted fluid supply. Its cap seals the system, preventing contamination and fluid loss while withstanding under-hood heat and exposure to brake fluid.
Over time, brake fluid reservoirs can become cracked, brittle, or warped due to heat and constant exposure to corrosive brake fluid. A compromised reservoir can lead to fluid leaks, low brake fluid levels, and ultimately reduced braking performance or failure. Replacing it restores integrity to the brake system and helps ensure a safer, more reliable driving experience.
Replace the brake fluid reservoir when you observe any of the following:
• Visible cracks, splits, or deformations in the reservoir body
• Fluid leaks around the cap or reservoir walls
• Discoloured or contaminated reservoir plastic
• Brake fluid level dropping frequently without visible brake system leaks
• During a brake system overhaul or master cylinder replacement
