Brake fluid DOT 4 20Ltr Textar


textar

Brake fluid is one of the most important fluids in a car as without it, stopping the vehicle safely would be impossible. The Brake fluid transmits the force exerted by the driver on the brake pedal onto the wheel brake. 
To ensure perfect operation of the brakes, the brake fluid must be changed regularly during inspection or maintenance and tested with the correct brake fluid tester.

Brake fluid should be changed every two years. 

The higher the DOT class, the higher the boiling temperature and wet boiling point. Higher DOT classes tend to allow longer maintenance intervals. The DOT standards are based on the American FMVSS-116 standard of the Department of Transportation (DOT).

Boiling Point and Viscosity

Dry Boiling Point - describes the property of the sealed new brake fluid. In this state, the brake fluid is almost anhydrous (substance containing no water). The dry boiling point is usually between 240 and 280°C.

Wet Boiling Point
 - determines the property of the brake fluid at the end of its life cycle, at a water content of 3.5% the fluid should be replaced. This defined wet boiling point must not be undercut.

Viscosity - describes the flow rate of the brake fluid. The lower the viscosity, the faster the brake fluid flows through the brake system, and the faster the brake signals are transmitted. 

Important Notes
• Brake fluid is poisonous and a hazardous waste.
• Be careful when changing. The fluid weakens paints and plastics.
• It must not come into contact with eyes or skin. Always rinse spilled liquid with water.
• Do not pour the liquid into drinking water or mix with used oil.
• The colour of the brake fluid reveals nothing about its quality.
• Brake fluid should be stored in its original packaging and in a dry, cool and well-ventilated place.

Product Information
Product Information
Brake discs, calipers, pads and brake master cylinders are the four cardinal points of each brake system; however, they are likely to be useless without the core of the entire system, the brake fluid. This component is so neglected as to be generally controlled in a summary fashion, with topping instead of a more appropriate replacement, at the change frequency recommended by the manufacturer.
brembo


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.

About Caliper Seals |Pistons

Porsche Caliper Seals & Pistons | Design911 Precision Hydraulic Components for Restoring Braking Power & Reliability

Caliper seals and pistons are vital hydraulic components in your Porsche’s braking system, ensuring smooth, consistent, and powerful brake performance. The piston transfers hydraulic pressure to the brake pads, while the seals maintain fluid integrity, preventing leaks and contamination. Over time, wear, heat, and moisture can compromise these parts — reducing braking efficiency and safety. Replacing caliper seals and pistons is essential for maintaining consistent pressure, pedal feel, and reliability.

At Design911, we offer a comprehensive range of caliper seals and pistons, engineered for precision fitment and durability. Each component is crafted from high-grade materials designed to resist corrosion, heat, and hydraulic fluid degradation. Perfect for servicing, performance upgrades, or complete caliper restoration, these components restore your Porsche’s braking response and ensure long-term dependability.

What Do Caliper Seals & Pistons Do?

These two components work together to create and maintain the hydraulic pressure that powers your Porsche’s braking system.

Core Functions:
• Pistons convert hydraulic pressure into clamping force against the brake pads.
• Seals prevent brake fluid leakage and maintain system pressure.
• Ensure smooth piston retraction for consistent pad contact.
• Protect against contaminants, moisture, and corrosion.
• Maintain balanced braking and pedal feel across all wheels.

High-quality seals and pistons ensure your Porsche delivers the stopping power, responsiveness, and control expected of its engineering pedigree.

Why Do Caliper Seals & Pistons Fail or Degrade?

Due to their exposure to heat, pressure, and environmental factors, these parts naturally deteriorate over time — especially in performance or high-mileage vehicles.

Common Causes of Failure Include:
• Seal wear or cracking from age and fluid degradation.
• Corrosion or pitting on pistons caused by moisture ingress.
• Brake fluid contamination leading to swelling or hardening.
• Heat damage from aggressive braking or track use.
• Improper installation or infrequent brake servicing.

When seals or pistons fail, symptoms such as fluid leaks, uneven braking, or sticking calipers can occur — compromising braking safety and performance.

Why Replace or Upgrade Your Porsche Caliper Seals & Pistons?
