noisy brakes

[hope to float]

Hi Guys,
Just what it says. The brakes are making a horrible noise when applied. It happened suddenly. Would they wear out like that? Is it a big job to replace them? I have never worked on wet brakes before. Found a YouTube video belonging to someone else

Kubota L3450 DT GST
Thanks

Have you changed the hydraulic oil recently? If so did you use Kubota super UDT? I have not seen this problem in the L Series but the m series it has been a common problem when not using Kubota fluids.

Not changed recently, but it is filled with Super UDT
