FAQs
What is DOT 4 brake fluid?
DOT 4 is a synthetic brake fluid designed for use in automotive hydraulic brake systems. It has a higher boiling point than DOT 3, reducing the risk of vapor lock.
When should I replace my brake fluid?
Brake fluid should be replaced according to your vehicle manufacturer's recommendations. Typically, this is every 1-2 years or 20,000-40,000 miles.
Can I mix DOT 4 with other types of brake fluid?
Carlube Brake Fluid DOT 4 mixes safely with other fluids. However, it's best practice to flush the system and use the recommended fluid for optimal performance.
What happens if I use the wrong type of brake fluid?
Using the wrong type of brake fluid can lead to reduced braking performance, component damage, and potential safety hazards. Always use the fluid recommended by your vehicle manufacturer.
How do I dispose of used brake fluid?
Dispose of used brake fluid properly at a recycling center or auto parts store that accepts automotive fluids. Do not pour it down the drain or into the environment.
Why is it important to replace brake fluid?
Brake fluid absorbs moisture over time, which can lower its boiling point and reduce braking performance. Replacing the fluid helps maintain optimal braking and prevents corrosion.
What are the performance levels of Carlube Brake Fluid DOT 4?
Carlube Brake Fluid DOT 4 meets or exceeds FMVSS 116 DOT 4, SAE J1703, and ISO 4925 standards.
Troubleshooting
Spongy brake pedal.
Bleed the brake system to remove air bubbles. Check for leaks in the brake lines and components.
Brakes feel weak or ineffective.
Check brake pads and rotors for wear. Ensure the brake fluid level is correct and bleed the brakes if necessary.
Brake fluid leaking.
Inspect brake lines, calipers, and master cylinder for leaks. Repair or replace damaged components.
