Product Information

Brake Master Cylinder 23mm bore
The FTE 23 mm brake master cylinder is an OEM-quality replacement designed for the Porsche 924 braking system. Manufactured as a direct replacement for Porsche part number 477611017A, it restores the hydraulic pressure required for safe, responsive, and consistent braking performance.

Fits:
Porsche 924 2.0L 1981>>

Brake master cylinder converts brake pedal input into hydraulic pressure, supplying brake fluid evenly throughout the braking system to provide safe, predictable, and consistent stopping performance.

Key Features & Benefits
• Genuine FTE OEM-quality hydraulic component
• Direct replacement for Porsche 477611017A
• 23 mm bore diameter
• Precision-machined internal components
• Reliable hydraulic pressure and pedal feel
• Durable seals for long service life
• Direct-fit installation with OEM-quality performance

Why Replacing the Brake Master Cylinder Matters
The brake master cylinder is one of the most important safety components on your Porsche. Over time, internal seals can wear and the cylinder bore may deteriorate, leading to reduced hydraulic pressure and compromised braking performance. Replacing a worn master cylinder restores firm pedal feel, reliable brake response, and overall braking safety.

When to Replace the Brake Master Cylinder
• Soft, spongy, or sinking brake pedal
• Brake fluid leaking from the master cylinder
• Reduced or inconsistent braking performance
• Internal seal failure causing loss of hydraulic pressure
• During a complete brake system restoration
• If corrosion or excessive wear is found during inspection

Diagram Ref No 1

Constructed from high-strength, multi-layer reinforced rubber with corrosion-resistant OE-style metal end fittings, the hose is engineered to withstand high hydraulic pressures, repeated steering and suspension movement, elevated braking temperatures and prolonged exposure to moisture, road salt and road debris. Precision-manufactured for direct OE-style fitment, it provides a secure, leak-free connection while maintaining the flexibility required for unrestricted front suspension and steering movement.

What This Product Does:

Transfers hydraulic brake fluid to the front brake caliper.
Maintains consistent hydraulic braking pressure.
Allows unrestricted steering and suspension movement without stressing the brake line.
Provides a secure, leak-free hydraulic connection.
Supports smooth, responsive and reliable braking performance.
Withstands high operating pressures and temperatures.
Helps maintain balanced front braking performance.
Forms an essential part of the vehicle's hydraulic braking system.

Symptoms Of Wear Or Failure:

Brake fluid leaks around the hose or fittings.
Soft or spongy brake pedal.
Cracked, split or perished rubber hose.
Bulging hose when brake pressure is applied.
Corroded or damaged metal fittings.
Reduced front braking performance.
Brake warning light caused by low brake fluid.
Front brake caliper sticking due to internal hose collapse.
Uneven front brake pad wear.
MOT or vehicle inspection failure due to deteriorated brake hose condition.

Why Replacement Matters:

Brake hoses are subjected to constant hydraulic pressure, repeated steering and suspension movement, high braking temperatures and continuous exposure to harsh environmental conditions. Over time, the rubber hose can deteriorate internally and externally, while corrosion may affect the metal fittings, increasing the risk of leaks, pressure loss or restricted brake fluid flow.
A failing brake hose can reduce braking performance, create an inconsistent brake pedal feel and, in severe cases, lead to partial or complete hydraulic brake failure. An internally collapsed hose may also prevent brake fluid from returning correctly, causing the front brake caliper to bind and accelerating brake pad and brake disc wear.
Replacing a worn or damaged front brake caliper hose restores safe, reliable hydraulic pressure and consistent braking performance. The OE Match replacement provides factory-style fitment, premium-quality reinforced construction and long-lasting durability, helping maintain the braking performance, safety and reliability expected from your Porsche.

Porsche 924 2.0L 1980-85

Constructed from high-strength, multi-layer reinforced rubber with corrosion-resistant OE-style metal end fittings, the hose is engineered to withstand extreme hydraulic pressures, repeated steering and suspension movement, elevated braking temperatures and continuous exposure to moisture, road salt and road debris. Precision-manufactured for direct OE-style installation, it provides a secure, leak-free connection while maintaining the flexibility required for unrestricted front suspension and steering movement.

What This Product Does:

Transfers hydraulic brake fluid to the front brake caliper.
Maintains consistent hydraulic braking pressure.
Allows unrestricted steering and suspension movement without placing stress on the brake line.
Provides a secure, leak-free hydraulic connection.
Supports smooth, responsive and reliable braking performance.
Withstands high operating pressures and braking temperatures.
Helps maintain balanced front braking performance.
Forms an essential part of the vehicle's hydraulic braking system.

Symptoms Of Wear Or Failure:
