Electrical gremlins and brakes

Hi,
I've recently had 3 small faults.

1)
I was riding in heavy rain and after putting the side stand down in gear the bike didn't cut out. The warning light work ok. Now all is back to normal.

2)
After washing the bike the radiator fans were constantly on (first time this happened), I've disconnected one of the 2 wires from the thermal switch, got home and reconnected it, works ok now.

and 3)

Not a fault exactly, but I've taken the front brake callipers off to check on the pad wear. The LHS is fine, whereas you can see the in the RHS calliper one of the pads is worn more that the other.


Now, is there something I could do to prevent 1&2? And I think I should be servicing the brakes with symptoms like that (bike is almost at 30k)?

Well the first couple sound like water was shorting out connections.

The brakes - are your discs floating properly on their bobbins? - if not, give them a clean.
Or, maybe your brake pistons are not moving quite as freely on one side and could do with a good clean.

Can I do anything to prevent them?

As for brakes, I do about 7k a year, rotors are cleaned 2-3 times a year, it might be possible I've bought the bike like this.

I'll pull the pads out and check the pistons for movement, and clean them with brake cleaner, sound good?

Cheers

If you can work out where things are shorting out, you may be able to provide some insulation - depending on the situation some heat-shrink, self-amalgamating tape or silicone grease might do the job for you.

With the brakes - sounds a plan :smt023 - of course, be careful not to pop the pistons right out by mistake - that can get a bit messy ....

Take the brakes off & check like D-rider says that the pistons are moving fine.
If you do a full strip & clean, as I did, not to difficult really, just need space & time to lay everything out.
Last little tip, if you do take the calipers appart for a full job, make sure you put them back together with the galeries between the two halves on each side lining up, sealing on the 'o' ring otherwise you are in a hole lot of pain! ask me, go on ask me Aaaaaaaahhhhhh!
