Vibration in front end while braking

Does anyone else have vibrations in the front end while applying a small amount of pressure to the brakes? I have 21,000 miles and have just started noticing these vibrations.

 

21k, definitely enough time to warp rotors. Get the rotors resurfaced if tolerance still in spec. Just take it to dealer. They may warranty this.

 

Rumble strip vibes?

Or buzzy brake pedal?

 

That's what I was figuring. How long should rotors last under normal use?

 

My rotos warped at 17k miles, dealer resurfaced under warranty.

 

It varies. Depends on your driving and braking. Mine are still decent, I am waiting on my wheels bearings before I change all of my brakes.

Some people have warped there's in 20k, others never have. Just varies

 

Long while. Depends how hard you are on them with driving conditions they're subjected to. Go by minimum thickness and cracking.
Usually can go through at least 3 sets of brake pads before changing them.

 

I was going to have it addressed at the 25,000 mile service. Hopefully it will be covered under the 30,000 mile warranty.

 

Improper lug nut torquing can cause rotor warpage.....either too tight and/or inconsistent torque between the lugs.

Quite common

 

You guys are jumping to rotors.

OP, Is it like a cell phone buzzing / pulsating feeling? A bunch of us have had issues with the brake accumulator on these trucks.

 

^^ this too, but I remembered you had small lugnuts before.

 

Yes.....yes I do

 

Not a buzzing. More of a vibration that causes the front end to bounce up and down under the right conditions.

 

Bouncing up and down describes something else, like out of balance tires. But you'd feel it in the steering wheel with either one. ABS, you'd feel in the pedal mostly.

 

Does it happen on decel between 25mph and 0? Does it feel like a rumble strip ?

 

It happens usually under 25 mph. It doesn't feel like rumble strips it's not as sharp or distinct as that.

 

My brand new 2017 has a little front end vibration when light braking. I was waiting for first service to mention it to the dealer.

 

I agree with the other. If you feel it in your pedal it is the rotors most likely. If you feel it in your steering wheel it is the tires/wheels. They need re-balancing.

Simple and most common OP, more so If you've had your tires rotated recently by shop or impact wrench.
IDK what your skill lvl is but if you can change a tire as per owner manual you can check it.
Or a trip to the stealer and insist they use a torque wrench, but good luck with that.

 

I have a torque wrench and can check it. Anyone know the specs?
