I was traveling on the freeway. Dry, sunny day. The esc light comes on for a half a second and the Wrangler brakes at the same time. Wheels did not lock up. Did not loose control. Just a split second, sudden deceleration. This has happened twice more, the last time was this weekend.
Start the vehicle after it has been sitting for a few hours there is an extremely hard brake pedal. You can press as hard as you can the vehicle rolls away for 5 to 10 seconds depending how long the vehicle has sat. The vehicle is a manual transmission so in order to start the clutch needs to be compressed thus putting you in neutral with no brakes. The emergency brake also does not work in the all the way up position. So when starting in the morning or after a few hours there are no brakes at all.
