FAQs

How often should I change my brake fluid?

It is recommended to change your brake fluid every two years or every 50,000 miles, or as recommended by your vehicle manufacturer.

Can I mix Prestone® DOT 4 with other brake fluids?

It is generally not recommended to mix brake fluids from different brands or specifications. Always refer to your vehicle's manual.

What does a high boiling point mean for brake fluid?

A high boiling point means the fluid is less likely to vaporize under high temperatures, reducing the risk of brake fade.

Why is it important to prevent corrosion in the brake system?

Corrosion can damage brake components, leading to leaks, reduced braking performance, and potential safety hazards.

Where should I store my brake fluid?

Store brake fluid in a tightly sealed container, away from direct sunlight, moisture, and extreme temperatures.

What is the difference between DOT 3 and DOT 4 brake fluid?

DOT 4 brake fluid generally has a higher boiling point and better performance than DOT 3, making it suitable for more demanding applications.

What should I do if brake fluid spills on my vehicle?

Wipe up the spill immediately and rinse the area with water, as brake fluid can damage paint.

Troubleshooting

Soft brake pedal feel.

This can indicate air in the brake lines or contaminated fluid. Bleed the brake system and replace the fluid if necessary.

Brake fade during heavy braking.

This could be due to the brake fluid overheating. Ensure the fluid is DOT 4 compliant and replace it if it's old.

Corrosion in the brake system.

This can lead to component failure. Replace the fluid and consider professional inspection for any damage.

Pros and Cons

Setup, Compatibility & Care

Compatibility:

  • Prestone® DOT 4 Brake Fluid is compatible with all braking systems that require DOT 4 fluid.
  • It is suitable for vehicles with ABS, disc, and drum brakes.

Setup:

  1. Preparation: Ensure the vehicle is parked on a level surface and the brake system is cool.
  2. Fluid Replacement: Consult your vehicle's owner's manual for specific instructions on brake fluid replacement.
  3. Bleeding: Bleed the brakes after fluid replacement to remove any air from the system.

Care:

  • Brake fluid absorbs moisture over time, so it's essential to replace it every two years or as recommended by the vehicle manufacturer.
