Knocking feeling/sound??

So I went for a drive last and when I got on a back road I decided to give the stopping power of my car a test.I got upto 100km/h and hit the brakes hard causing the front brakes to lock up and skid.I did this 4 times just to get more comfortable about hitting the brakes hard if needed and how much distance I would travel until stopped etc... (about 15 metres I think).

Anyways now there's a knocking feeling/sound coming through the front wheels.It's not bad but I want to fix it ASAP.I can feel it a little bit through the steering whell but more so on the foot rest for my left foot (automatic car).It happens with each rotation of the wheel.

I'm thinking it's the wheels alignment cause when I braked hard I could feel it pull to the side a bit on the last time.Also it looks a bit out of alignment (could just be me though).
I don't think it's the brakes cause I can't feel it through the brakes at all.
Any help is greatly appreciated :thumbsup:

could be ur steering racks damaged, or possibly hub bearing. jack it up, see if u can move ur wheel from side to side.

Thanks man.Will do :thumbsup:

Will it still be Ok to drive a couple of hundred km's?

Or maybe you flat spotted your tyre. Next time when you brake hard, don't lock up your tyres. Modulate the pedal to avoid locking up.

Yeah I thought that could be it.I checked around my tyres.There's definately flat spots there but I'm pretty sure there's 4.I will have to check that better when I jack it up tonight after work.
Thanks for the braking tip too aaronng.

does ur car have abs ?

how long did u lock up for ???

i would say it is flat spots...

I pretty sure it dosen't have abs.
Each time was about 3 seconds.
I hope it's flat spots=no repair bill.
Thanks Shifty

Was gonna say flat spots but already done.

Good to hear I hope it is...

flat spot means u should get tyres especially if u said u have 4 flat spots on each tyres!

lol... defect and not safe....

get some new tyres and learn 2 ease on and of the brakes not just slam on them.... especially in non abs equipped vehicles...

I aint got the dosh to buy new tyres...
I'll just have to drive till it wears them normal again.
And yup,wont be doing that again...
