Maintain proper performance of the braking system in your 2007-2008 Jeep Grand Cherokee 3.0L CRD with new brake fluid. Despite being a closed system, brake fluid will eventually begin to collect moisture. As a result, the braking performance will begin to suffer due to the decreased boiling point caused by the water. Although the brakes are an essential part of your driving experience, brake fluid is often one of the most neglected fluids in a vehicle. Manufacturers often advise changing the brake fluid every two to three years or after a certain number of miles. Following the manufacturer's suggested maintenance schedule is crucial, as is occasionally checking your brake fluid. DOT 3, DOT 4, DOT 5, and DOT 5.1 are just a few of the brake fluids that are readily available. The DOT 3 and DOT 4 brake fluids are the most commonly used. DOT 4 brake fluid has a greater boiling point than DOT 3, despite the fact that the two are interchangeable. Shop XDP for all the leading producers of brake fluid including Lucas Oil, and more!
