under braking ...

was driving along A38 the day, came off the slip road doing normal speed, braking normally then all of a sudden whole car started bouncing and had weird feelings coming bk thru the steering wheel. coaxed it round the the roundabout and it seemed ok, took it upto 40 and then it started again. managed to get it into morrisons car park, gave all the wheels a kick and a wriggle. couldnt see or feel anything out of the ordinary. did my shopping and drove home, slowly took her bk above 40 and nothing, applied brakes and got the usual feelings, took her upto 70 and all was fine.

took her to kwik fit to get tracking and wheels balanced as she;s been pulling left, braking right, and was a slight wobble in wheel at motorway speeds. tracking was toeing out 7, what ever that means, and one wheel was unbalanced.

drove it back to the base and all was fine, nae wobbles, nae pulling etc.

should i still be worried, and if so any ideas as to what it was?

ps had new front discs and pads fitted about 1500miles ago, but they look ok.

cheers folk
