New 2015 Tacoma has chirping sound

If you have a 09+ TRD OR 4x4... you have the electric boosted master cylinder, unlike any other 2nd gen tacoma.

the squish squeak is simply break fluid flowing through the master cylinder.

There is also the accumulator pump which will run from time to time (every 2-5 pedal pushes) to build brake pressure. This is all 100% normal.

 

I have a 2015 TRD Off Road double cab... I got it in March and since day 1 the brake pedals makes a "squish" type sound. Any way of eliminating this noise?

 

no, you will get used to the sound.

And the first time you use atrac, you will respect the electric boosted master cylinder.

 

And 100% annoying
