Nah, just rusty

Seriously, a quick rub down with some wet and dry, a dab of kurust, followed by a smearing of grease and you should be good to go, for a while.

Ye gods though, the original brake pipes, even the seriously exposed ones, on my 15 year old Volvo, still look brand new, shocking work by JLR. They could be in league with the brake fluid producers..... .

Will it come up on mot?

Doesn't look corroded - no pitting or flaking, and easy for the tester to get a close look at / give it a tap.... .
