Front brake lockup while off-roading

I have been experiencing my front brakes locking up while off-roading. Yesterday I was at Hungry Valley OHV in Ca, for an amazing day of trail riding. I kept having my front brakes intermittently lock up while on the trail. For One or two seconds, they would literally lock and tires would slide. I know this is definitely not normal. It could be dangerous if this happened at just the wrong time. Anyone have any ideas what’s up with this?? I’d like to figure it out and obviously stop it from happening. Pics for attention

 

is it both or do you feel 1 or the other? besides vsc thinking maybe pistons getting stuck.

 

Pedal did pulsate. Not sure on noise but possibly.

 

Just fees “gritty” and feels like it locks up and slides.

 

that does sound like the vsc/abs.

 

Don’t think the pistons are sticking. Brakes feel perfect otherwise, but “lock” up when wheeling hard. Fast trails, lots of bumps, at 30+ mph.

 

Usually around turns, again at decent speed. Definitely not slow or crawling.

 

Gritty, sliding feeling is the best way to describe it. On hard banked turns, and flat turns. For 1-3 seconds.

 

Ok, will do. Thanks for that. Just to confirm, hold down the VSC button for 5 seconds to turn it off?

 

Ok, curveball. My truck is a 2013 Baja edition. No VSC button. Now what??.

 

I think I got it now. The button that says off with the burnout tracks

 

Be STOPPED, press and hold that switch for 5 seconds till dash lights come on AND CHANGE.

This still wont kill abs however. (only being in 4lo with the rear locked will from the factory)

have a look into the ABS on the fly kill switch, this will kill the ABS and VSC whenever you want.
