Electronic Brake Assist Issue?
Had my LS for three weeks now. Love it, mostly. But when I brake from any speed above 35 MPH down to zero, such a coming up to a traffic light, I cannot get my 2009 AWD LS to slow down evenly. Even with consistent foot pedal pressure, my LS still has a tendency to slow down quicker, then less….especially when it gets closer to stopping completely. My foot pressure hasn’t changed at all. It won’t slow down in a linear sense? At least it feels that way.
I get no steering wheel issues or vibration issues when applying the brakes at any speeds (like you do with a warped rotor.)
Is it the LS’s electronic brake assistance or its electronic brake force distribution that would cause this affect? Do All LS’s do this? Is it normal? Or is it a brake pad issue?
I do not like it.

You might have a bad brake actuator. There were quite a few brake actuator issues on the 2007 and 2008 cars. I had it on a brand new 2008 and it took Lexus a year to acknowledge that it was bad. It's expensive to replace - about $3K.
I have not heard too many complaints about the 2010+ model years though.

Wish it was as simple as replacing the brake actuator. That was one of the first things I replaced since getting the car in Feb. It made the brake clicking noise go away but the jerky uneven braking remained...
