Good Maintenance Practices:

  • It is important to completely flush or bleed your brake fluid and replace with new fluid when the fluid has become dark or contaminated to ensure the highest levels of performance. Extreme applications like driving down mountain roads, driving or towing with heavy loads, and racing increase the rate at which your brake fluid deteriorates and will create the need for it to be changed more often.
  • Always follow vehicle manufacturer's recommendations when adding brake fluid.
  • Do not remove master cylinder cover until area is clean of foreign matter.

Troubleshooting Tips:

  • If your brake pedal feels mushy or goes all the way to the floor under heavy or repeated use, it could be a sign that your brake fluid is old and needs to be changed.
  • Poor or old brake fluid could result in brake failure or delayed brake response. This is prevented by changing your brake fluid when necessary, and using the vehicle manufacturer recommended brake fluid for your vehicle.

Frequently Asked Questions

No, ACDelco recommends that only trained professionals change brake fluid. Correctly flushing, filling and bleeding the system is critical to braking performance.

Yes, add new fluid whenever the fluid reservoir shows fluid is needed. Additionally, change your brake fluid if the reservoir fluid is dark, murky or has significant contamination.

No, DOT 3 can be added to a DOT 4 system but only if it is absolutely necessary, for example the fluid level is critically low. After getting to a safe area it will be necessary to flush out the system and add the correct amount of new DOT 4 fluid.

No, adding fluid is a normal practice as the brakes wear. However, when changing the brake fluid the system must always be flushed first, this is the only way the system can be cleaned of contaminants. After refilling with clean fluid the system must be properly bled, otherwise the fluid level will be too low and the system may not work as needed.

Yes, DOT 4 has a higher boiling point than DOT 3 and can be used instead of DOT 3.

Yes, the color of the new brake fluid is not critical as long as the brake fluid specification matches what is recommended for your vehicle. Only the brake fluid specification is critical.

No, DOT 5 cannot be mixed with DOT 3 or DOT 4 brake fluid.

No, while the fluid level can go down due to leaks, most often the fluid level will go down as the brake pads and rotors/drums wear and the calipers must push farther to make the system work.
