yaris jerks when braking

[Elements604]

Hello I recently Purchased a 07 yaris hb automatic with 94,000km.

I never noticed this on the test drive but after an hour from buying it I noticed that the car feels like its jerking when I apply the brakes. Doesnt matter the speed it does it till a complete stop, in every gear.

Could it be warped rotor or something else?

Sure sounds like warped rotor. That would be my first check as well.

id either vote for warped rotor or mayeb your not use to the auto downshifting (i believe the auto yaris downshifts as u slow down, i have a 5 speed personally)

its definitely not the downshifting because it does it even when i put the car in neutral and apply the brakes.

Try to have the throttle body clean. It's close to 100K km.

Mine shutters too when I brake, pretty sure mine is a warped rotor, I had the same problem on my older car.

Do you mean it's "shuddering" like shaking? Or do you mean there is a low vibration noise?

I have a shuddering feeling (feels like the RPM is going too low) when I hard break, but my car has always done that.
