Loud ABS Noise upon activation - Is it normal?

Hello all - new to the Tundra forum - been playing with a 99 LandCruiser for a while though.

Recently acquired a 2012 Dual Cab 4x4 with the 5.7L motor. Before buying it was told the brakes were very soft, even after a master cylinder replacement, and that it had been sitting for close to a year (also why I paid way below the asking price). Did have soft and uneven brakes so I replaced all the pads and rotors, fortunately all the calipers were in good shape.

Process firmed up the brakes quite a bit and they are now very smooth, but with still a little more pedal play than I would like. Haven't fully bled yet as I'm still getting TIS setup on a laptop.

Prior to changing the brakes I slammed on them to activate the ABS and it made a lot of noise, definitely more than I'm used to on any of my other vehicles. After the brake change was forced to slam on to avoid a less than helpful driver, and again very noisy. Question is: is this normal for the Tundra's or do I need to be looking at the ABS module for repair/replacement? Drives completely normal and no dash warning lights.

Thanks much for any insight!

 

Tundras have "electronic brake force distribution" and "brake assist" which is fancy for "the truck decides how much pressure needs applied in certain situations.

I thought mine was soft too but they are fine. It takes some getting use to. My abs went off yesterday and it sounded like someone was blending gravel in the back seat.

Here's a list of nannies, what they do and if you can control them.

 

Blending gravel in the back seat is the perfect description of the sound it made. Guess I'm glad to know that's the "normal" sound.

Thanks for the diagram also - now it's time to go find somewhere to get this truck dirty

 

Be careful. These trucks are tough but not tanks. Haha

 

just to clarify, the proper sequence to turn every nanny off would be, push and let go once, then push and hold, then push and hold again, correct?

 

I had a 2010 and now a 2018. On both the pedal seems to go down farther than I’d expect, but when I slam on the pedal it stops good. I’ve switched pads and rotors too and it’s the same. It does take getting used to. Also if you use ceramic pads, they will feel softer than metal.

 

yep. whenever im dealing with snow, slick, loose gravel, etc, i press, and then press and hold till the lights come back on again. basically if im not on pavement, thats the mode i use. if im on pavement, i only do the single press, and only when im in so much snow that i'm worried about loosing momentum up a hill.
