Diagram ref no 9
The brake master cylinder is a core hydraulic component in the braking system that converts the mechanical force from the brake pedal into hydraulic pressure. This pressure is transmitted through brake lines to the brake calipers at each wheel, enabling the vehicle to slow and stop effectively. Proper function of the master cylinder is essential for consistent brake feel and safe stopping performance.
The brake master cylinder is essential for safe operation of the brake system. Over time, internal seals and components can wear, leading to:
• Soft or spongy brake pedal feel
• Reduced hydraulic pressure
• Inconsistent stopping distances
• Visible fluid leaks under the dash or near the cylinder.
Replacing a worn or failing master cylinder with a TRW replacement restores proper hydraulic pressure, improves brake responsiveness, and enhances overall safety - especially critical on performance vehicles like the Porsche 911.
Replace this master cylinder if you notice:
• Brake pedal sinks or feels spongy
• Decreased brake performance
• Internal or external fluid leaks
• During a full brake system overhaul or restoration
• When upgrading to OEM-spec braking components

DOT 4
Having an extremely high boiling point and lower viscosity than required, it meets and greatly exceeds regulatory standards. Also suitable for vehicles with ABS.
Vapour Lock formation
This sort of habit leaves room for the Vapour Lock, the formation of vapour bubbles due to boiling of the brake fluid that replace the normal fluid and are compressed, thereby sending the brake pedal to its fill stoke (spongy pedal). The origin is incident in the porosity of the tubes that make up the braking circuit, which in time draw moisture into the fluid, drastically reducing the boiling point. The result is a reduced braking efficiency.
Brembo Premium Brake Fluid
Brembo Premium brake fluids have a higher boiling point that exceeds the standard, thus offering superior resistance to the Vapour Lock and ensuring braking efficiency even at low temperatures. With high anti-corrosion properties and resistance to oxidation, Brembo brake fluid also allows for long-term unaltered chemical/physical characteristics of the fluid in operating circuit; therefore, preserving its integrity.
