When braking our 2006 toyota highlander the brakes seem to catch then release, catch and release. this is on dry pavement. the local toyota dealer service says this is normal operation and is because the battery recharging mechanism is taking over. this may be true but i am of the opinion that there is something wrong. when you apply the brakes and it reacts in the way it does you tend to want to easy up on the brakes because the car lurches a bit but that is the wrong thing to do! *tr
