2 dr 2015 JK sport with 33 x 12.5 x 15 general tire grabbers. 52,000km. Pulling out of a church I had to stop quicky as a car came speeding around a bend that I didn't see..my brakes didn't work like normal and felt very "floaty" Is best way I can describe. They worked very slowly and I almost didn't stop. It did this the next time I tried to brake again. After parking for a hour and driving again all seems normal and brake are responsive. Has anyone else experienced this before?

Interesting. Not in a good way. Something similar happened to my 2015 JKU. I noticed it after it had been sitting untouched for 2-3 days in cold weather. It self corrected itself once warmed up. Were your brakes hot? Did you just come down a hill? Was the Jeep sitting for days before driving ?

Scary Brakes! Check out the Wayalife video of the Black Bear Run were a guy came to one of the ''Steps'' were you have to do a three point turn and his brakes went to the floor and only four feet from the edge!

I had driven it the night before and this morning on my way to my location. I was at the location for about an hour and a half then drove and noticed it immediately. It may have been a slight down hill brake but nothing crazy. It wasn't that cold today around freezing temp.

Are you sure your ABS didn't activate and the feeling you had in the pedal is the pulsing/vibration of the ABS system? Was it wet on the road? Even if dry, you may have activated the ABS with a hard stop and cold tires.

No I'm pretty sure it wasn't the abs. There wasn't a vibration it just felt like the brakes didn't work as quick or tight as usual..it took my foot going to the floor and it still didn't stop right away. It felt floaty or delayed.

I've had the same thing once. Was getting ready to pull out of a parking lot. Hit the brakes at the stop sign and they went to the floor and the jeep came to a stop very slowly. Has not done it since. At least I know I'm not the only one it happened to.

Have any of you messed with your vacuum pump, for example moving it or unplugging it for installation of aftermarket bumpers? Or winch? I wonder if it loses connection it has to reset itself someway. When it happened to me I had just unplugged and plugged it back in temporarily the day before. I didn't move it or disconnect the hoses, only the electrical harness.

Might want to inspect your brake pads and make sure they're not worn to the point of needing changed. With the pedal going to the floor and still not really stopping your Jeep it almost seems like it needs a brake bleed.

Lots of useless input (mine would be as well If all I did was provide anecdotal evidence of a similar occurrence).
Hopefully HERE is some useful input - IT'S YOUR Brakes, They Malfunctioned, Get Your Jeep to a Brake Specialist Before You Kill yourself or worse - Someone Else.

Jeezus.

Good to hear. IF possible, avoid driving your Jeep in the interim. If that was a Warning - Not heeding it would be a tragedy IF something happened.
Get those checked Sooner than Later.

Remember, Your "Emergency Brake" is just that.
- Press and Hold the button (Do Not release the button)
- Pull the handle Up
- It actuates the Rear Brakes Only so, you get Less braking power BUT...

Practice that. Few people can rally that move in an Emergency moment.

32,000 miles in 1 year? I hope you've taken it in at least once or twice for some form of maintenance. If you do your own maintenance make sure you check the pads every 15K miles..

I have 20K on my 2013.. The pedal can feel spongy at times just off idle .. don't know why, but it just does it. On the other hand, I've had to stand on my brakes a few times when traveling between 30-40 mph and it stops like a champ. I've had it sideways, tires growling and straightened right up.. I was amazed. I also had a close call a few weeks back as I was on a wet surface.. Stood on the pedal and it modulated itself to a safe stop.. Again, I was like wow, ABS is working.

The JK has the beef.. just not sure what this low rpm/idle thing is all about..

My Chevy does it too, but that has hydro-assist..

Depending on the nature of the miles that amount may represent the end of life for those brakes. Jeeps chew on brakes especially rears with the he BLD.
Fronts normally get eaten on all relatively heavy vehicles.

I don't do my own maintenance but it goes to the dealer for oil changes and regular checks every 5k km. I've been diligent with my appointments.

I took mine in after it happened. "Could not duplicate customers concerns". Brakes checked out fine. Still had about 80% of the pads left.
