2019 Sigma 4 started developing this irritating noise when the brake pedal is pressed with a light foot. Have had it checked and worked upon from 2 different 3S dealers, the sound comes back after a while. Anyone else have had the same issues, what's the solution ?The sound is like that of a 'Tik' ... metal to metal strike sound.
what was the last work done specially on the brakes?
When brakes pad changed and is it genuine or local as once I used local made that give me so much noise
Brake pads changed by Toyota themselves. Disc turning by Toyota. Brake booster changed in some recall of this vehicle.
The sound has been coming even from before, previously brake pads were changed by Toyota as well.
is it an even thumping sound?
Nope. just 'tick' ....'tick' whenever the pedal is pressed lightly. Something like the cylinder striking the back plate of the brake pad.
It could be related to brake pad retainer clips. Dealership is adjusting it for you on each visit, but it goes bad again. Ask them to replace it for you.
