Does your car need a specific brake fluid?

Although DOT 3 and DOT 4 fluids are all glycol-based, the chemical composition of each type of fluid is different, so it will have a different effect on the system. To ensure that the system works as it should, it is imperative to keep using the exact brake fluid recommended by the manufacturer.

Are all brake fluids compatible?

All DOT 3, 4 and 5.1 brake fluids are compatible with each other and with all systems. If the brake fluid becomes unable to control the pH or other corrosive elements, the rubber and metal parts will deteriorate over time.

Does different brake fluid make a difference?

The higher the DOT classification, the higher the boiling point, thus the better the fluid is at resisting heat. That’s why racers use DOT 4, not DOT 3, brake fluid.

When to bleed brakes?

You need to bleed brakes whenever the brake system has been opened to air and when your brake pedal feels a little soft or spongy. Brake bleeding is a good maintenance procedure to ensure there is fresh, clean fluid in the brake system.

Does brake fluid expire?

Most brake fluid manufacturers state that a sealed bottle has no set expiration date. In a sense, the fluid doesn’t break down over time and offers the same level of performance even after years on the shelf.

Can brake lines freeze?

The cold air will end up freezing the brake lines which will create noticeable noises like grinding and squeaking after you step on the brake pedal. That is why every auto mechanic will tell you that changing your brake pads periodically is essential in order to protect the brake line of your vehicle.

Can brake fluid boil?

This results in high temperatures which, in extreme cases, can cause the brake fluid to boil. However, when the brake fluid starts to boil, the brake pedal slackens and the braking power drops significantly. When brake fluid boils, vapour locks are produced that can be compressed.
