Unfortunately had to drive her in the rain today which is something I never intentionally do. Car developed a sound that I can only describe as like 2 smooth metal plates being rubbed together. Can't hear at higher speed but up to about 40mph in 4th can certainly get it when pressing the throttle.
Anyone else ever experienced similar or have ideas what it could be? Thanks.
Ps - only happens when car is moving so lifting bonnet to hear gives nothing.

Slightly sticking caliper? Maybe the pads rubbing on a brake disc?

hope it is as simple as that. Interesting how it started while driving in wet conditions and was wondering if was to do with water in the discs ... as you can probably gather, I have the technical knowledge of a 5 year old. Just like driving the thing and leave up-keep to the experts.

afew questions, is the sound coming from the rear, and does it stop under breaking?

is sounds like it's coming from the front of the car for certain. I'd done about 45 miles and was driving slowly through a village and gently started to accelerate when I heard what I can only describe as a metal on metal sound - not really loud but enough to hear it. As I sped up it stopped but I was easily able to replicate the sound by doing the same thing ... slowing down and accelerating again.

Its never easy diagnostics? almost got it right. only wat to see if breaks is to jac up the front of car and have a tinker.

If you can do "left foot braking" then you could try just gently applying the brake when the sound occurs to see if it changes/goes but keeping the power applied so the car doesn't slow...

Do bear in mind that your left foot is used to just depressing the clutch so has a LOT less finesse than your right (well, that's certainly true of me!) - unless you're (a) on private land and (b)confident you can be very delicate please don't try this....

I've done it before and it's difficult but not impossible.

Alternatively jack the front up and spin the wheels whilst listening closely..
