Slight Screeching sound 40-60 mph

[KAZUYA]

Hey Guys!

Just an odd sound i noticed today which i figure may be normal, But wanted to get opinion.

Driving in Corsa I hear a slight screeching sound around 40 - 60 mph then it stops.
Almost like if they would be the disk breaks being applied heavily or something which is not the case..
Once i exceed 60 MPH noise stops.

I am assuming all is well and this is normal... i don't notice any oddities during the drive.

Def different peculiar engine sounds with Corsa on...

I had a similar issue when coming to a standstill however heavy braking a few times sorted it

Same issue here, sorted basically the same way.
It was raining when you heard that brake noise? It may sound like a weird question but it makes sense if this was the case.

Mine makes a slight high pitched whistle at light throttle and low RPMs. It's easy to replicate at 30 mph, I plan to ask the dealer about it the next time it's in for service (which I hope isn't until the first annual.) It reminds me of a throttle body whistle I had on an LT1 Z28 many many moons ago.

screeching brakes usually are from steels.. due to the temporary rust,
CCB tho..
