Probably more steering wheel shake/judder under light braking than hard braking.

Front pads and discs changed 4 years and 30,000 miles ago......unable to tell if pattern or genuine VX parts were used.

Any idea, chaps?

Invoice for £176.47 in April 2010.....which looks like one hour of labour  was required at £40 P/H plus VAT


Of course, the wobble/judder may have SFA to do with the discs and pads.

Maybe drop links away ??

I hear much about these drop links .

What are they and where are they located?

Expensive?

Easy fix?

Won`t cause OP`s problems. Sounds like warped discs

I can also feel a judder/groan/grind through the brake pedal that is not the ABS kicking in.

How long do front discs and pads generally last?

[05omegav6]

Pads 5-25k depending on use...

Discs 10-50k depending on pad abuse

methinks our good doctor is in need of some new discs and pads and also some sensors by the sound of his description ! beware of some pattern discs as you may end up with warped discs and more judder.

Doctor Opti, I wonder if you are in the habit of holding the car on the foot-brake for short pauses after normal road braking? You describe the classic symptoms of warped discs due to such action. With braking, obviously the discs become hot and cool when the brakes are released, but if you hold the car on the foot-brake the disc area between the brake pads does not get a chance to cool, whereas the rest of the disc does - hence differential cooling takes place and the disc warps.

Look under the car at the inboard face of the frint brake discs. If there is a rusty band on the outer edge then replace the discs.

If not, front wishbone bushes are flapping about, although this usually gives a flapining or tank slapper( in bike parlance ) feel to the steering.


....as said, drop links are NOT responsible.

I have a works van when I brake the wheels shake. Had strut mounts, wish bones, brake pads n discs turned out it was drop links. Would I not be wise to check before he spends money on discs n pads. Only a suggestion n all

Omega drop links have ball joints on each end. The slightest amount of play and they knock. Any knock is evident way before any effect on handling and body roll is evident.

It would indeed be wise though. But given the geometric set up and suspension design on omegas, it's not possible for the wheels to flap or the brakes to vibrate with drop link play. ...roll bar bush play might. But NOT the drop links themselves. Luckily, roll bar bushes on omega are a very rare failure.

Take a front wheel off & you can't help but see one

Fronts discs came up as an 'advisory' at the MOT in June.

001 Front brake discs worn,pitted or scored. But not seriously weakened.

Thanks, Andy.

They look relatively easy to replace if required.

No knocking noises at present.
