Restoration after immersion - what needs doing? I'm taking my usual approach to learning how to fix things - I've acquired a bike in need of repair (for free!), and am working it out as I go along. In this case, the bike got caught in a flood and spent a week or so under a couple of metres of river water. 

So far, I've disassembled and cleaned everything, and so far as I can tell: 


The bottom bracket is dead, so I'm getting a new one. 
The frame, somewhat surprisingly, seems fine: no signs of rust anywhere.  
The brake disks had some minor surface rusting that came off with the mud, and now seem fine. 
The headset bearings were full of river water, so I've disassembled and de-greased, and will be re-greasing when I reassemble it. 
Given that all of the other bearings were knackered, I assumed the same for the wheel bearings, so have cleaned and re-greased both.  
The whole drivetrain seems OK, after much cleaning.  
The pedals are a bit rusty, but I'll be swapping them anyway, so I'm not bothered.
The shifter cables seem OK. 


For things that I know I'm not sure about: 


What do I do with the front suspension? Previous bikes have all been road bikes, so I've no idea what I'm even looking for here. It's one of these. I assume the river water will have done a nasty on it, but what's the best way to go about fixing it? 
This bike has hydraulic brakes (Tektro M286). What do I need to check about these? Any likely problems?


Finally, is there anything that I've not listed above that might have been damaged and not be obvious at a glance?
I'd consider replacing the shifter cables and housings, as this is a relatively low cost fix. Water will have seeped deep into the housings.

The hydraulic brakes are of course nominally sealed, but a bleed may be good idea in case water has got into the system. The braking system is obviously critical so I'd do it.

Water probably got past the fork seals. You don't want that sitting in the fork and the seals are not preventing it from coming out. If it's a coil fork it should come apart fairly easily (search youtube for videos), if it's air it's trickier. I notice there are service manual downloads on the Suntour page.
