    Brake Pedal Rattle

    2015 JK Brake pedal rattle

    We took our new 2015 JKU Rubicon out for its first off road adventure and I noticed this loud rattle coming from the brake pedal.

    It only happens while driving over rough terrain at any speed. At first I thought it was coming from the steering column but, I quickly realized the noise stopped when I had my foot on the brake pedal.The rattle also stops if I pull up on the brake pedal with my foot.

    Soon, I plan to take a close look to see if there are any loose bolts or Iinkage in the brake pedal assembly.

    I'll update this thread when I have more info but, in the meantime, has anyone run into this problem? If so, please post up your experience.

    I have not had this issue in my own jeep, or heard of it yet. Curious to see what you can find out tho.

    Is your jeep a manual or automatic?

    it's your abs kicking in, if you have the override switch you can disable it when off road.
    i see you have a rubicon, use the switch to turn off the esp/abs, it'll activate automatically if you turn off the jeep so you'll need to turn it off each time you go wheeling

    I had the something similar happening on my 08' six speed. Turned out it was one of my hydraulic lines hitting the heat shield.

    This isn't Tony's first rodeo and I can assure you that it's not his ABS kicking in. It seems to be localized to the pedal and without having given it a closer look, I would have to guess it's a bushing or something around that area that isn't quite on just right.

    yeah, i just read it again. 1st time I read it i was thinking the pedal shudder when driving fast on rough terrain. i used to get it on mine and more often with the 315's driving fast on rough terrain until i did the steering wheel dance to shut it off.

    Thanks Eddie and Jeeeep!

    To be honest, when I first heard it I thought to myself, "oh, the abs just kicked in" because that's almost what it sounds like. Well, I'm certain that's not what's causing the noise.

    Like Eddie mentioned, it's probably a bushing in the brake lever system.

    I guarantee I will figure out what it us and report back. In the meantime, I have way more important things to do.

About us
“wayoflife” is a moniker that I’ve been using for 20 years now and I chose it because I think it does a great job of explaining, in simple terms, the passion I have for Jeeps and the Jeep way of life. This is a lifestyle that transcends age, gender and race as the only thing you need to be a part of it is a love for the outdoors, a desire to explore, a yearning to take on a challenge and a will to conquer it. Over the years, Cindy and I have attempted to capture the essence of this lifestyle through photographs and videos and share it with others around the world. And, this is how WAYALIFE was born.
