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.

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.

Notes:

• Sold Individually
• 2001 thru 2024 will take 2 quarts if you are planning on flushing the system.
