"Grabby" brake behavior? - Page 2 - GreenHybrid

Not sure about the grabby brake behavior, but the gurgling behind the dash sounds to me like the Plasmacluster (which ionizes water molecules behind the driver's side air vent).

I have noticed that when I decelerate to a stop (lets just say from about 50mph), I can slow down smoothly except for the final couple of feet. It feels like the disc brakes are grabbing suddenly, and it makes it feel like a semi-panic stop for those last couple of feet. It borders on embarassing when I have someone in the car riding with me. I can also feel a transition if I am creeping forward with the foot on the brake.

In addition, I have noticed that sometimes it seems difficult to keep the car from creeping forward at a stop light without applying what seems to be excessive pressure to the brake pedal. My foot can actually get tired. At the same time, when I am stationary, with my foot on the brake, I can have the energy monitor showing that the wheels are feeding power to the battery, and if I step on the brake harder (and hear/feel that subtle "thump" transition), the flow of power will stop.

DOES ANYONE ELSE SEE THESE SORTS OF THINGS?

Thanks!

I'm not sure I woudl clasify it as last few feet or basically below a certoan speed and I think the brake behavir varies a little at low speed depending oth whether the ICE is running or not. I notice sometimes the car grabs well and the car stops on dime, and other times it is like the brakes are slipping. And worse the conditkon can change in mid-braking depending (at least what I think) on what the ICE is doing or in the middle of doing. I'm not looking to place blame, but I am realtively sure this behavior was what contributed to me hitting the back of a SUV 2 months ago. Since getting the car back I leave way more braking room and distance between the vehicel in front of me than I have in any car for the last 25 years. I noticed it again the other day, the brake feel suddently felt different as I was braking and I had to lean harder into the brakes.

I assume you are talking about my gurgling sound. It was (as I expected) an incomplete refill of the cooling system after they replaced my radiators (engine and inverter) following my deer collision.
