I have a theory on the surge when stopped issue that keeps popping up on this forum and would like any feedback on it that anyone might have. My 2002 SR5 2WD with 97K occasionally does it depending on how I stop. I am very easy on it having had my share of "hard" driving in my younger days. A few weeks ago I ordered all parts for the timing belt/water pump replacement job and figured with 97K it would probably need brakes all around so ordered them too. After the timing belt/water pump replacement job was complete, I checked the front pads and they still had about .120" of pad left, Toyota says minimum is .060". Since they start out about .400", I figured they would have gone another 12-15K but I changed them out anyway. I then removed the rear drums and to my surprise they showed almost no wear at all. I did not replace them at this time. I got to reading up in the official Toyota manual and best I can tell the action of the emergency brake engagement keeps the rear drum brakes adjusted. Well, I almost never use my emergency brake and am wondering if this has anything to do with the lack of wear on my shoes. I activated and released the emergency brake about 50 times and they did tighten up some obvious by a couple of threads showing on the adjustment screws without crud on them. To my theory, I have always felt that the surge we disuss was caused by the rear brakes making a crude sloppy release in some way, just due to the feel and sound when it happens. I drove my truck a couple times after this rear brake adjustment and the surge is not there (however, it may come back), when I stop and then go it feels much smoother at the point where the surge usually occurs. By the way, I just checked my driveline a couple days ago and it appears perfect, no slop, spline not sticking in tranny, etc. I do not buy that as the cause of MY surge, anyway. Has this been investigated by anyone else?
