my 1 year old up with 18k on the clock has developed a new fault! on normal motorway driving its fine, but when I brake gently from any high speed my steering wheel shakes and the brake pedal vibrates as well. I have looked under the car and i have noticed the two drive shafts from the gearbox to each of the front wheels have a few mm of play in a linear direction (not rotational) can anyone else please go under their car and just check if this is normal? im going to the dealer tomorrow but they have a habbit of fobbing me off, like when I pointed out to them the lights dont go up high enough.

any ideas?

Hey my polo had the exact same problem! When I took it to my mates garage they called it juddery brakes and I needed new pads and disks! Its just started happening to my sister but she wont take it in! And my neighbour says its a kown thing in vws! So my advise take it to a garage and ask them to look at it!

No doubt others will say different and fare dos but as I've been there its worth to just get checked out! Edited by: Itzben

I got this on my current car, and its called warped disks. This happens after alot of wear on the brakes. This can also happen if you heat up the disks too much.

Braking long and gently is the surest way to warping the disks ... and these are the tell-tale symptoms.

what a cop out

This doesnt happen on my mazda after 70k miles
this didnt happen with my ford after 80k miles
this didnt happen with my nissan after 80k miles

if you are not allowed to use the brakes like this on a vw, then they are not fit for purpose!

I have just got off the phone with the dealer who wants to charge me £250+ to replace the brake pads and discs on a car that is ONE year old! This is a total scam and I will not be paying a penny! how vw can sell a car that the brakes warp when you sit on the motorway, not touching the brake pedal, using the criuse control to maintain speed, etc, is absolutely criminal!

DO NOT BUY A VW OR A VW UP, unless you want to replace the entire front brakes every year

I have experienced this on a few cars I have owned. It's always been down to either the tracking being out or that the wheels need rebalancing.Simple and inexpensive to correct. (unless it's tracking on a merc). Could be caused by hitting a large pothole or one of the balancing weights falling off. Edited by: Rooster

Dunno. It just always happened when breaking for me.

Definitely sounds like warped discs to me.

Having no true account of your driving style, I can't comment on how it happened in your specific instance, but in general warped discs occur when too much heat is generated in a braking system. This is normally when people brake too early and too gently (long periods of friction between pad and disc), or riding the brake pedal when on a decline (heat generated through prolonged braking).

It can happen to a 50 mile old car if not driven properly, the fact your car has 18k on the clock is irrelevant.

Again, I'm not pointing fingers, I have no first-hand knowledge of your driving style. I'm merely explaining how carped discs 'can' occur through driving style.

What is regarded as "warping" (brake judder) is 95% of the time actually uneven build-up of brake pad material on the surface of the disc due to incorrect bedding-in of the brakes or bad braking habits.

The cure is to even out the disc again, either by undergoing a re-bedding in procedure, or more reliably, a disc skim followed imemdiately by proper bedding in to prevent reoccurence.

There have already been a few cases where warped disks on the up! have been replaced under warranty.

Probably not what he wants to hear ...

The issue is further worsened when people then stay on the brakes when they are stopped : the heat can't get out as easily.


For braking gently, I use engine braking.

Oh, I just sold my previous car with 120.000+ miles, and the original brake pads & disks.

Well my Up had this happening after only a few thousand miles and in my case it was a fault with the car so you might want to check it out with the garage.

I have had Volkswagens since 1978 and have never had brake judder. My 1976 Ford Escort Mexico suffered from it and discs and pads were replaced under warranty although they did try to worm their way out of it.

I was warned away from engine braking. It is fine to simply ease off the accelerator, and let the car slow naturally. But if engine braking means changing down to a low gear, then releasing the accelerator, and the engine then significantly slows the car, that puts strain on the gear train. Brake pads are cheap, the gear train isn't.

Could a few bouts of heavy braking help clean the disks, if it is debris on them? Occasional heavy braking is recommended to remove any build up of rust.

Just back from the dealer with a new set of discs and pads on my car which retail for £300!

the problem is gone, but they wouldnt let me keep the old discs and pads saying "they needed to go back"

Absoloutly disgusting from vw treatment. I measured the temperature of the discs after a 60 mile drive on the motorway - 40 degrees. I'm buying a kia for my next car.



VW - where our discs warp at 40c and all our staff at the dealer location drive ford cars! - we know something you don't!

£300 for front disc and pads! I thought VW used a menu pricing system for this £249 is price on a Golf Mk 6. Did they do additional work tracking, wheel balance or anything?

My partner's UP has just been booked in to have the discs replaced for the second time due to this. The first time VW would only pay 75percent of the cost due to the car being more than six months old. After a 'discussion' they paid the full amount. That was in June and now the same has happened. Her previous car was a Fox which did 75,000 miles on the original discs so I don't think her driving style can be blamed. I'm thinking either they are very substandard discs or there is another underlying problem which needs to be looked at.
