Judder when braking down through around 40mph?
Discussion
I have a Mazda 2 which has developed what I'd call a "judder" when braking down through around 40mph.
So for example driving around town braking is fine.
Dual carriageway braking down from 70mph is fine until around 40mph when there's judder which then seems to disappear from around 30mph downwards.
Car drives straight with no judder and brakes straight and tyres are almost new.
Appreciate it would need looking at as I know nothing about cars but does that sounds like the front discs are the most likely thing?
The pads and discs are still on their originals as the car hasn't done many miles.

Forgive a silly question but just having a quick look online to get an idea what discs should cost to get changed and most online quote sites seem to let you quote on pads, pads and discs, but not just discs.
Should pads be done at the same time?

Change the pads as well, they wear to the disc and you want to rule out a problem.
It would be interesting to run a dial gauge to measure any run out on the current discs.
Makes sense but I'm not even vaguely mechanical It would be interesting to run a dial gauge to measure any run out on the current discs.
There's a few online price quote things but even with those prices vary massively so any ideas what you might expect a decent local indy to do pads and discs for?
Slight dilemma going on about whether to keep the car and the common sense part of my brain says sort that out and it'a perfectly good little car.

I would not change a car just for the fact it had a judder.
A modern car should not be much in labour to change discs and pads…maybe £200-300 plus the cost of the parts.
I did the rears on my boxster on Friday, start to finish was about an hour of my time.
Thanks, the online sites come up with £200-300 so it sounds like it can vary quite a bit just for the sake of trying a few places locally, and that wouldn't be the reason for considering changing, sort the judder and there's absolutely nothing at all wrong with the car - but knowing me I'll sort the judder then change it anyway so it's money down the drain.A modern car should not be much in labour to change discs and pads…maybe £200-300 plus the cost of the parts.

Unlikey on a car with sufficiently few miles on the clock to still be on its original disks and pads?
As much as I know nothing about cars it drives absolutely straight and without any sign of any noise or wobble or anything else.It's literally just this judder which seems like clockwork to occur when braking down through 40mph and goes at around 30mph.
Doesn't seem to matter if you're coming down from 45mph or 70mph.
