i've just bought a polo gt, and the guy i bought it off said it had some G40 discs and green stuff pads
anyway, i've noticed that under gentle braking, the steering tends to judder
if you stomp on the brakes, this doesnt occur
just wondering if anyone has experienced anything similar? the discs dont looked warped, although i havent had the wheels off to properly check
GT? This is polog40.co.uk!! :D On a serious note just because the discs dont look warped doesnt mean they arent. Get a flat edge to them and have a look. If it has G40 discs they will be vented. Sounds to me to be something loose or maybe worn. Are all the wheel/caliper/steering rack etc bolts tight? Have a good check over it and see what you can find...
cheers "jez1272g40", lol
to be fair i used to own a g40, but i bought a gt because im hoping it will be more reliable than the old g-wagon! saying that, the gt hasnt proved its worth yet! :)
Have a look at the anti roll bar bushes to see if they have worn. If not see if the steering and track arms are good. I assume your tracking is spot on and your wheels balanced ?
it seems to go in a straight line, ill check those things outon saturday when i can get it in the air, thats if i can get the ramp legs under :-\
are the g40 and gt calipers different? is the only diff between the gt and g40 discs the size? im assumming there slightly bigger for the g?
calipers are different. The discs are the same size but g40 ones are vented (hence thicker).

I vote for the anti roll bar bushes being worn; look for shiny areas each side of the bush where the bar is moving side to side. I had the same issue and new bushes sorted it. Powerflex ones are best.
is it a ballache of a job to do? how much did the powerflex bushes set you back?
this was caused by air in the brake lines, seems to be sorted now
