I have early GQ wagon and recently I can feel a severe shudder back through the steering wheel but only while braking. Has anyone had this problem or have any idea of the cause.

seems it may well be excess runnout on your front brake discs,
get a brake mechanics opinion, it is eliminated by machining the discs and fitting new pads.
Is caused by normal operation, ie heating and cooling.. but can be accelerated by having red hot discs and then suddenly cooling them in creeks etc..This may eventually also cause fatigue cracks.

Andrew I only had the discs and pads done approx 8 months ago so I don't think the problem's there. thanks for follow up. Sol

Hi Sol Get your discs checked again for run out. Disks that have been skimmed down to near the minimum are more prone to warping, also make shure that wheel nuts are only ever tightened by hand overtightening can warp discs! Regards Ken.

Sol,
I would suggest that you check the calliper slides, to see if they are stuck, they may need cleaning and greasing. I've had a similar problem with disc brakes on a car. I would get the discs machined and the brakes would work fine, till eventually the shuddering would start again. Whilst it was the disc being warped that actually caused the shuddering, it was the stuck calliper slides that were causing the disc to warp, because all the braking force was being applied to one side of the disc.
