Brake master cylinder & DOT4 brake fluid – Porsche 993 C2 1995–98 by Kits is a brake hydraulic package for Porsche 993 C2 models. Kits packages group related parts and consumables, helping the installer check the contents before work begins.
What This Product Does The brake master cylinder changes brake pedal movement into hydraulic fluid pressure for the calipers. The supplied DOT4 brake fluid is used when filling and bleeding the hydraulic circuit during replacement. For a complete brake fluid flush on a Porsche 993, you will need 1.5 to 2 liters of DOT 4 brake fluid. While the actual system capacity is only around 1 to 1.2 liters, purchasing 2 liters ensures you have enough to completely purge the old fluid from the lines and bleed the clutch slave cylinder.
Functions
- Creates hydraulic pressure from brake pedal input.
- Feeds pressure through the brake lines to the calipers.
- Helps maintain hydraulic balance across the braking circuits.
- Works with the reservoir, lines and calipers as part of the brake system.
- Supports fluid renewal during master cylinder replacement.
Symptoms of Fault
- Spongy, soft or sinking brake pedal.
- Loss of pressure while holding the pedal.
- Brake fluid leaks at the rear of the cylinder.
- Air entering the hydraulic system.
- Brake warning lights or uneven braking prompting inspection.
- Visible wear to related discs or pads during brake checks.
Why Replacement Matters Internal seals and cylinder bores can wear with age, heat cycles or moisture-contaminated brake fluid. Replacing a worn or leaking master cylinder during a hydraulic refresh helps return the system to the correct operating condition. Compare the kit contents with the job list and add any seals, clips or one-time-use hardware if not included.

FAQs
- Are kits vehicle-specific? Often yes; confirm model, year, engine and any relevant option codes.
- Do kits include all one-time-use hardware? Not always; review the contents list for bolts, clips, fluids and seals.
- Any fitting tip? Compare the package contents with the Porsche PET diagram and your workshop job list before starting.

This kit is comprised of the following items:
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.

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.
