Garage pulling a fast one?

Hope the new discs are from a different supplier maybe Citroen would be a good source.

So they were not rust then!

There was a bit of rust on one of them, on the side that faces into the car.

These ones were from a company called National, the mechanic said that he's put different branded ones on this time. so fingers crossed!

Thanks for your help and advice MX5

All brake discs rust if a car is stood a while. Braking removes it. I can't imagine brake discs would warp after such a short time, certainly not so badly to cause any noticeable problem. I believe keeping on the foot brake at traffic lights can cause discs to warp as it transfers built-up heat to them.

Usually if the discs are replaced with non-genuine cheaper alternatives , you will find that after a time they tend to judder due to the metal being a lower quality than the genuine ones. Basically they should have been replaced with a decent brand and not as I suspect dirt cheap ones.

We had a picasso and it did 45K on the original brakes. Even then only the pads needed changing - not the disks

£270 for discs, pads and a tyre is a right rip off.
did you pay main dealer prices then?
you could have easily saved £80.
e.g front discs and pads around £80 (mintex or ebc, good makes) fitting of discs and pads £50, so £130 total.
then a tyre fitted and balanced for a picasso is around £60 for dunlop/goodyear, a good brand.

had a Renault Scenic 9 1/2 years old, 109000 miles, same discs as when we left the Renault dealer all those years aggo...I carry quite a lot of weight in the car AND I am a demon late braker....only ever needed pads, get the details of the manufacturer and drop them a line yourself

Brake disks don't often warp although its a common expression. What can happen is the the discs can get very hot when stopping from high speed - eg if you have to stop at the lights on a fast road. If you keep your foot on the pedal while stopped some of the brake pad material can transfer to the disk causing an uneven surface which results in run-out and the effect the OP describes. This is not the same as warping. Might be something worth considering when the new disks have been fitted.

it is possible for brakes to warp from being hot and getting cooled quickly eg a big puddle
it could also have been the calipers were not greased on fitting the new discs causing dragging brakes = heating the discs
same if they didnt ensure the hub face was clean and even

The garage is talking out of its !!!!. Brake discs do not warp - ever. Brake discs can suffer a small buildup of pad material leading to uneven braking, which can be removed with a lathe.

Brake discs will always rust, but 2 seconds of braking will remove the rust from the surface. The rust around the edge, and the hub, will always remain, and is quite normal.
