Hi All,
Advice on the following appreciated:
A few days ago I had the rear tyres changed on my 306. Since then, there has been a fair bit of vibration whilst braking. Can anyone confirm that this would be a symptom of poorly balanced wheels please?
Thanks in advance.

As it only happens while braking,would think it more likely to be either worn pads or distorted discs/both would cause it.

Go back to who changed the tyres and have them check them for balance. Do not let them take the weights off first then balance it again, have them spin them up as is and then re-balance if required. It may be a faulty tyre although quite why it does it under breaking not sure sub side wall distortion can cause this. Regards Peter

Thanks for the replies.
The vibration did start immediately after the new tyres were fitted. I'm therefore inclined to agree that the problem is more likely to be related to poor balance or a faulty tyre rather than a problem with the brakes.
Mind you, being a Peugeot, vibrating brakes wouldn't be anything new!
Thanks again.

Poor balance normaaly manifests itself through the steering on the fronts and through the seat of you pants at the back and when the car is free running. However since the common dinominator is the tyre change then I would check them first. As suggested get the tyre depot to spin them up first before they remove the weights.
Once had car where the rear wheel was not sitting true on the hub and it manifested itself under braking and at no other time.

Fullchat,
Interesting that you make reference to a "wheel not sitting true on the hub". A few years ago, I had vibration from the rear wheels under braking and this is exactly what was diagnosed by a main dealer. I didn't believe them as I didn't really think it was possible.
Starting to think it may be worthwhile removing the wheels and refitting them myself now before I return to the tyre fitters.

a "wheel not sitting true on the hub"
I would have thought it unusual nowadays for tyres not to be balanced when they are fitted. However it's not unknown for a wheel to be clamped off-centre on the balancer - I have watched it done to one of mine, and it was obvious to my eye, but seemingly not to the fitter's, who was just looking at the readout. If no-one noticed, presumably it would feel pretty bad on the car, where it is difficult to fit off-centre with 4 or 5 nuts.

A possible is two of the four nuts/bolts are not tight maybe causing either disc or drum (if not secured to hub)to go out of straight untill either pads or shoes are applied to straighten,which would cause it.Just a thought
