Jeep produced the 2008 Wrangler in the X, Unlimited X, X RHD and Sahara trim levels. All of the Wrangler models were powered by a 202-horsepower, 3.8-liter, fuel-injected V-6 engine. The brake system used a vacuum booster to increase braking power while reducing effort at the pedal, and an anti-lock brake system for safety and improved traction control. Air bubbles trapped in the brake system can lead to spongy brakes and reduced braking performance, and must be purged to restore the brakes to their proper feel and performance.
