steering wheel movement whilst braking

Hi,
I've noticed recently that when I brake at speeds of approx 50mph and above I get left and right shaking on the steering wheel. I was wondering what everyone's thoughts are for the cause?
Unfortunately I have to drive up the kerb every day at work onto the grass which could have caused this problem 
I have a very nice set of 12 spoke alloys but won't put them on whilst I am working where I do as they are in mint condition!
Could it be one of the bushes has gone or wheel balance?
Cheers,
Mondeoman

Could be warped discs or worn bushes or track-rod ends

I had the same problem a few weeks ago, new discs and pads plus a couple of bushes cured it

Anyway of telling if the discs are warped as I don't want to spend money on stuff which I don't need?
I guess if I get it up on the ramps it will be easy to tell if bushes or track rod ends are broken?

I fitted brakemaster discs to the front only 12k miles ago and with going through all this water with hot discs they are now giving me the same problem you have, they are only 12 quid each.

I had exact same problem. Changed discs = no help, bleeded brakes = no help, changed front calipers = everything fine!

I've had the car checked over and a wheel bearing needs replacing as the wheel has some movement as well as a new set of pads.
I wonder if this will cause the wobble or if their is something else causing it?

I wonder if it's just the wheels that need a balance? Big wheels notoriously give a shake at around the speed you are talking about when badly balanced. If the car doesn't do it at 60+ mph, or 40 mph I would be putting my money on the balance.

It can`t be the balance of the tires. If the tires are out of balance the shaking would be regardless of braking or not. It is most likely bad disc or stuck calipers.

Pjot. Perhaps you are right. However, my 12 spoke wheels gave exactly these symptoms and were found to be only balanced on the inside of the rims. Out of balance wheels prevently show when braking, or under hard acceleration. Never say it CAN'T be such and such unless you are absolutely sure! Many years ago I have done a nine month course at the Dunlop factory, wheel balance can be the cause of many problems, shaking CAN be just certain speed related. Especially because of the size of wheel.

hi there
you can get the wheels balanced only on the inside rim. it's called static balancing.

Aye, but 'static-balancing' is next to useless! Dynamic balancing is really the ONLY way to get the right balance between tyre and wheel! A lot of people don't realise that when balancing a wheel, you are NOT actually balancing the wheel. You are in reality balancing the new tyre to the rim that it is fitted to. The Wheel should already be in perfect straight condition, a real good true workshop would take your bare wheel and check that it is straight first, and make sure it was balanced. Then balance your new tyre onto that wheel allowing for the previous setting of the rim balance. Alternatively you get get an individual 'on-car' balance, that would allow for your suspension and steering adjustments as well. I only remember all this because of old, wheels of all sorts need to be balanced. I used to balance Locomotive wheels that weighed a good few tons, but early on in my apprenticeship I balanced car wheels on an old 'Hoffman' balancer.

Violent shaking of the steering when braking at speed (the faster you are going, the heavier it shakes) is in my experience, due to warped discs

Im with JC on this one  . As for wheel balancing, there are some companys that do 'on car' balancing  . I had my Range Rover done with this method as standard balancing couldnt get rid of a wheel wobble at 70 mph. The difference it made was huge  . Not cheap though. Around £20 per corner

Yep you're right JC, but I didn't see anywhere mentioned about the faster and heavier bit!

The speed of 50mph & above was mentioned, although it wasn't mentioned that the shaking when braking got heavier at a higher speed (which it will if the discs are warped), I was just implying that this would be the case
Mondeoman...do you know what brand of discs you have fitted, as some cheap brands tend to be prone to warping. I've personally had problems with 'Apec' discs before on two occasions & they were very cheap....about £10 a disc if I remember rightly

Sorry for long time before reply, but I've had the car in the garage for service and MOT etc and hoped they would solve the problem, but they have not!
They found the rear discs are warped which have been replaced, but the ones on the front are like new and they believe are perfectly ok. I still have the steering wheel wobble and they have suggested a couple of possible causes:
They have advised me that the front bottom arm bushes appear to be soft, not split
They think all the shockers are soft, but they passed the MOT!
Not wanting to keep spending money replacing parts which are not at fault, anybody have further ideas to the cause?
The wobble is worst around the 56mph mark but is also present at higher speeds. When the car decreases below 56mph the problem seems to go away

Your last post rules out my first thought of wheel balance. I would be looking at those soft bushes for a start. Funny how it present at higher speeds as well as 56 mph. One question you could ask yourself, is this wobble more prevalent when you brake, (weight on the suspension) or when you accelerate, (weight off the suspension) that may help the diagnostic.

Oh, it's caused when you brake, not with acceleration etc
