The Brake Booster Without Brake Light Switch is a genuine OEM Porsche component designed to enhance braking performance by amplifying the force applied from the brake pedal to the braking system. Installed between the brake pedal and master cylinder, this vacuum-assisted unit ensures smooth, responsive braking while reducing the physical effort required by the driver.

What This Product Does:
- Amplifies braking force using vacuum assistance
- Reduces brake pedal effort for improved driver comfort
- Enhances braking response and control
- Maintains consistent and predictable pedal feel
- Supports safe and efficient braking performance
Symptoms Of Wear Or Failure:
- Hard or stiff brake pedal requiring excessive force
- Increased stopping distances
- Hissing noise when braking (indicating a vacuum leak)
- Engine idle fluctuations when pressing the brake pedal
- Inconsistent or reduced braking performance
Why Replacement Matters:
- Restores proper braking assistance and responsiveness
- Improves stopping power and driver control
- Prevents additional strain on braking system components
- Eliminates vacuum leaks that can affect engine performance
- Ensures safe braking, particularly in emergency situations

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.
