DOT 4 Brake Fluid Castrol Mobil Mannol

✅ Leading Brands in Hydraulic Brake Fluids

• Castrol (Brake Fluid DOT 4): The gold standard in protection. Its advanced formula has an extremely high boiling point, ideal for trucks that face constant braking in mountainous terrain.
• Mobil (Brake Fluid): Recognized for its superior thermal stability and ability to maintain perfect viscosity in both freezing and intensely hot climates
• Mannol (DOT-4): High-performance engineering that offers excellent corrosion protection, protecting the system's cylinders and rubber seals to prevent costly leaks.

💎 Advantages of Our Premium Brand E-Liquids

• Protection against Humidity (Hygroscopy): Our brands contain additives that neutralize water absorption, preventing the liquid from degrading and causing internal rust in the pipes.
• Zero Compression: The fluid maintains its constant volume under extreme pressure, ensuring that the force you apply to the pedal reaches the brake pads in full.
• Seal and Gasket Care: Formulated to not swell or soften rubber components, keeping the system airtight for longer
• Vapor Resistance: A higher boiling point prevents the liquid from turning into gas, eliminating the "spongy pedal" feeling.
• Boiling Point Above 230°C: Extreme thermal protection for prolonged braking on inclines

🚛 Security Critical Applications

• Braking on Steep Slopes: Prevents vapor lock when descending mountains with a 30-ton load
• Operation in Extreme Climates: Maintains perfect viscosity from -40°C to +230°C
• Hydraulic Brake Systems: Compatible with all DOT 3 and DOT 4 systems
• Component Protection: Protects master cylinders, wheel cylinders, ABS valves and seals

• Keep the work area well ventilated
• Use appropriate personal protective equipment (gloves, goggles)
• Wash your hands after handling brake fluid

Pollution Prevention:

• Never reuse brake fluid drained from the system
• Use only clean, dedicated brake fluid containers
• Do not allow water, oil, or dirt to enter the liquid.
• Close the container immediately after use
• Do not mix different brands or types of brake fluid
• Use clean, dry funnels to fill the reservoir

Product Lifespan:

• Unopened liquid has a shelf life of approximately 2-3 years
• Once opened, use within 12 months.
• Check the manufacturing date on the packaging
• Discard the product if it shows sediment or a change in color.
• The fluid in the system must be changed annually

⚠️ Warning: Brake fluid is toxic if swallowed. Keep out of reach of children. If swallowed, do not induce vomiting and seek immediate medical attention. It is corrosive to vehicle paint.

🔧 Why Invest in Premium Brake Fluid

Using generic brake fluid is like playing Russian roulette on a downhill slope. The heat from the brake drums transfers to the fluid; if it's not high-quality (like Castrol or Mobil), it will boil and the truck won't stop. This is a critical investment in the safety of your drivers and your cargo.

Signs that you need to change your brake fluid:

• Spongy pedal or pedal that goes all the way to the floor during prolonged braking
• The liquid is dark or cloudy (it should be clear or light amber)
• It's been over 12 months since the last change
• Experience loss of braking efficiency on inclines
• The system has been opened for cylinder or valve repairs.

Maintenance Recommendations:

• Bleed and change the fluid every year: Ensures that your valves and cylinders always work in a clean and moisture-free environment
• Use only premium brand DOT 4 fluid - never mix with generic fluids
• Inspect the tank level weekly during pre-trip inspections
• Check for leaks in lines, connections, or cylinders
• Bleed the system completely after any brake system repairs
• Store containers tightly closed to prevent moisture absorption

Fluid Change Procedure:

• Park on a level surface and apply the parking brake
• Locate the brake fluid reservoir (usually near the master cylinder)
• Clean the area around the tank before opening
• Remove the old fluid from the reservoir using a syringe or pump.
• Fill the reservoir with new DOT 4 fluid to the maximum level
• Bleed the system starting with the wheel furthest from the master cylinder
• Continue bleeding each wheel in sequence until clean fluid comes out
• Check the reservoir level and refill as needed
• Test the brake pedal - it should feel firm and not spongy.
• Inspect for leaks at all connections

System Purge Procedure:

• You will need an assistant to pump the brake pedal
• Connect a clear hose to the purge valve
• Submerge the other end of the hose in a container with clean liquid
• Have the assistant pump the pedal 3-4 times and hold it down.
• Open the bleed valve while the pedal is pressed.
• Close the valve before the assistant releases the pedal.
• Repeat until clear liquid without air bubbles comes out
• Check and refill the reservoir frequently during the process

Recommended Purge Order:

• 1. Right rear wheel (furthest from the master cylinder)
• 2. Left rear wheel
• 3. Right front wheel
• 4. Left front wheel (closest to the master cylinder)

Liquid Inspection:

• The new fluid should be clear or light amber.
• Dark liquid indicates contamination or degradation
• Cloudy liquid indicates the presence of moisture
• Sediments indicate internal corrosion of the system.
• Check the level weekly - a drop in level indicates a leak

Pro Tips:

• Never reuse brake fluid drained from the system
• Use only liquid from recently opened sealed containers
• Clean up any brake fluid spills immediately.
• Document the date of each fluid change
• Consider changing the fluid before long mountain trips.
• Check the boiling point of the liquid with a tester if available
