Quite bad steering wheel shake under breaking.

[Stevieabz]

Depending on how hard I break will depend on how hard and fast the steering wheel shakes. Haven't had the car long but don't remember it being this bad when I first got it. I did change the spring on her not long ago, that might be a causal factor? Any help is appreciated.

Sounds to me like a warped brake disc.

[Stevieabz]

take the wheel off and check the front disc? Can they be 'unwarped'?

[maxfield]

I'd start by jacking it up, spinning the wheels make sure something's nothing is seized cause it to warp.

There's no real way of telling if a disc is warped unless you have a dti gauge handy.

You can't unwrap discs, would require new ones.

[Stevieabz]

Yeah I think its time for new disc anyway the cars done nearly 150k on the originals. Thanks for the advise, I'll take a look tomorrow.

New disc's and pads.Plus make sure caliper pistons and slides are not seized and working correctly.

Major cause of shaking under braking.

Check the wheelnuts are tight as a first step.

[Stevieabz]

Wheel nuts were not tight enough! Simple as that, thanks guys!

[Speedtouch]

Good to hear that, dude. Always pays to check the basics first.

Check the seating area for the bolts of the wheel(s) in question. They could well be scrap.
