Any tips for squealing front and rear disc brakes on a brand new bike? Apart from cleaning and aligning which i’ve already done.

Hi, you could try a vinegar based window cleaner on the discs, we find this works better than the best "disc cleaners". If that doesn't work the pads could be contaminated, it would be worth putting in a new set.

All the best, David

I had that on the halfords vengeance, even after cleaning with disc brake cleaner, didn't go away. Go vack to shop and ask them to replace pads with different type. Otherwise you have stones/ grit stuck to both pads. Very annoying isn't it.
Or could be they just have to bed in.

Try repeadly braking HARD on the affected brake - worked for me - I was always tentative with my front brake and, as a result, it never really got properly 'worn in' but this advice worked for me

Mine tend to squeak when they get wet.
Ignore it, as Amoto65 says, it is a useful warning device and probably a shriek of brakes is far more alarming to dozy dog walkers and earphone wearing air heads than a ting from a bell.
