Vibration in brake pedal when turning
Noticed it twice when going through right hand turns at 20-30mph. It is a rapid vibration that feels like ABS/traction control kicking in. Feels like the power drops off, but I don't see any illumination on the dash. The Jeep has had a 2.5"BB lift and 35's for about a year, but I didn't worry about centering the steering wheel until about a month or so ago (2,000 miles after the lift installation).
Since the steering wasn't centered the ESP/BAS was always on so I guess this problem may have never showed up until now? Would the ESP/BAS illuminate if it was activated?

I would think it is your ABS kicking in due to the fact that the tires are turning at a different rate/speed, because the outside tire has to turn faster then the inside tire while making a turn.

It's probably the ABS, but I'm not sure why it'd do that. I've read a lot on here that our computers don't like it when we change stuff, so it could be the lift and tires. Try centering your steering wheel. I'm no expert, but that seems to be a common answer

It's the traction control (ESP), mine only does one or two quick flashes. At first I didn't see flashing but since it happened to me on the same turn everyday I began to look for it and sure enough it would blink.

Why are you braking while turning? Unless coming to a yield you should accelerate during a turn. My brake pedal vibrates braking in a straight line due to knobby tires.

Thanks for the info. I'm usually braking because it is a sharp turn at an intersection and I forget when going between my cars and the Jeep that there different reactions to sharp curves, lol.
The problem doesn't show up real often and really I have to be going pretty extreme for it to start. After suffering with death wobble I get paranoid when the Jeep does any kind of shimmy so I had to ask.
I'll look into the procal, probably needed a problem before I convinced myself I needed it.

I have the same problem. Fully stock JKU. It happens when breaking on left or right turns when pulling into parking lots. It's more common when there's an incline into the parking lot. No dash lights for me. It feels like ABS but it can't be normal.

Same on my stock 2010 jku sport (17 inch wheels, 32 inch sra's). Happens once in a while when I take a hard right and apply light brakes. It definitely feels like ABS, but no lights. Perhaps because it's so fast?
