Don't know if this is the correct area about my problem.

I have an AU2, year 2000 vehicle and have been experiencing engine shudder when braking to a stop. It's momentary and goes away when I'm fully stopped.

Been like that for a while.

I would like to know what might be causing it so I can stop that shudder effect.

Has anyone else experienced this? What was the cause.

I don't know if I have a faulty PCV Valve or being caused by a leaky intake manifold gasket.

Bondy.

So vehicle is moving, you brake, and the car shudders?
Sounds like warped rotors to me.
Get them skimmed or replace them.

Oh ok,
Seems like it was from the engine. Never gave the rotors a thought of causing the problem.
