Front Brake Disc "Tramlines"

[Bedlam]

Was giving the wheels of my 57 2.0 TFSI FR DSG a good clean yesterday and noticed two things:
1. One of the discs (front offside) has far more noticable "tramlines" than the other 3 discs. The vehicle was bought from Seat dealer in Feb 09 at 14 months old (don't ask me where it's been) with 500 miles on and has now covered 4000 miles, it has not been "ragged" at all and no heavy braking, it is factory standard - do I have a problem?

One suspicion is that the disc may be warped - any thoughts?:
After reading the many excellant posts on here I have also been considering a 4 wheel alignment for peace of mind and wonder whether I can score one if I can convince a dealer the disc needs replacement?

2. The front nearside alloy wheel has a miniscule stone chip on it - is there any DIY repair I can do?

Appreciate any thoughts from anyone

just a thought but the calliper isnt semi siezed is it ? maybe causing the pads to rub on the disk. If the disk is warped you would know when braking hardish, the brake pedal will be pumping back (abit like abs but not as harsh) not sure why you would 4 wheel allignment ? unless you have hit any pot holes etc, 4 wheel allignment checks the camber, castor and tracking of your car, nothing to do with the brakes, its pretty exspensive too, so unless your getting uneaven tyre wear i wouldnt bother.
For the stone chip on your alloy i know there is a company that will come out in a van and repair chips/scuffs on alloys. il have a quick search on google now see if i can find them!

just had a look and its www.wickedwheels.co.uk i was thinking about

Thanks for the advice on chip

The reason for considering the 4 wheel alignment is that some of the consensus on this forum is that they can and do come out of the factory mis-aligned, in fact I had a new Landrover Freelander that was born as a crab and that was scary

I would rather spend £'s on a check of this to ensure max tyre mileage rather than wait for wear indication and therefore "premature" change.
Particularly as I don't drive like a Formula 1 driver "much" and that any adjustments should be relatively simple (in adjustment labour cost) as the car is virtually "as new"

yeah i see where your coming from, i work at a tyre firm as a saturday job just for some extra cash. done quite a few allignments on mx5 track day cars, they have been crabbing and doing allsorts and we had them straightened out. Be good to know how you get on though, if it is out or not

What do you mean by tram lines?

If its several lines on the disc face, that may be caused by debris or stones caught between the pad and disc, engraving fine lines into the disc surface.
Pretty much 0% chance of the disc warping.

Yes I do mean what you describe and you are probably correct, but they are far more evident on just this one disc and the others are virtually smooth.
I have driven 4000 miles out of the 4500 covered and have had no signs of debris i.e. squeal/noise.
The warped opinion came fom someone who knows no more than me!
