Hi All:

My 2016 Sahara has 23,000 miles on it and has had regular maintenance from the time I purchased it, with 4 miles on the odometer.

Took a 1000 mile road trip and near the end of that trip, brake pedal began squeaking and there was a TINY bit of extra travel in the pedal in order to get it to respond.

Took it to the dealer, they investigated, and said it was a bad master cylinder.
Master cylinder replaced under warranty (thank my lucky stars for that), and after a couple of weeks, the pedal was squeaking again, but no play in the pedal, and brakes function as expected.

Checked new master cylinder for leaks, there are none. Called the dealer and they said it could be some switch that wears out, or a variety of other things that they didn't name.

Has anyone had this issue? Or have any ideas if a squeaky pedal is something to be concerned about? The Jeep is now out of warranty, and it would be great to have some ideas as to what the problem might be before taking it back to the dealer.

Thanks!

Do you feel any vibration in the steering wheel when you depress the pedal? It's very slight, but definitely coincides with pressing the brake. : )

My 13 and 16 both sqeak! I think it's when letting the brake pedal off, not application, but I'll be more in-tune to diagnose! It's a nuisance for sure!

its the rubber boot the brake rod moves though on the cabin side.. try some very light coating of spray lube on it and see if it helps.

This seems to be a common problem on all JKs. My 2013 JKU has a squeaky brake pedal too. I have sprayed lubricant in the rubber boot under the dash but it does not help.

I appreciate all of the responses, thanks! I would be happy to try the spray lubricant in the boot under the dash, but I can't seem to get to it. I can't even see it when I lie on the floor on the driver's side. Not sure what I'm missing here . . . .

Pull the knee bolster plastic piece off (below the steering column), behind it there’s a metal plate with two bolts, remove, shine a light under the dash and look through the opening. You’ll see the boot in question right through. Use a lubricant with a straw attachment, insert straw into boot and spray...
