I'm not sure I understand what you are saying, but have you had the bike upside down?

Temperature shouldnt make any difference ( to a point) How worn are the pads? This weather you should be using sintered rather than organic , as they will wear quickly. With the pads worn, it may give a squidgy lever.

If the brakes are a closed design with an adjuster like the old Giant MPH and Hope C2 then they will be affected by temperature, my old c2 need adjusting on hot and cold days and after overheating if you drag the brakes too much.

Interesting topic. I have sqeeky brakes on my specialised MB. Obviously needs new disc pads. Anyone know what tools are needed and how to replace them?.

What brakes are they? Most are pretty easy:

1) Remove wheel
2) Push pistons back into caliper by sliding a thick screwdriver between the old pads (or using the end of a ring spanner once the pads are removed). I normally cycle the lever a little and repeat the pushing a few times so that the pistons are scraped clean by the seals.
3) Remove retaining pin on the pads and slide the old pads out (some are top, some are bottom).
4) Insert new pads with retaining pin.
5) Re-install front wheel and squeeze lever a few times to get the pads biting properly.
6) To ensure that the pads are hitting the disc square and evenly I normally use a fine screwdriver to push one pad or the other across the disc while gently pumping the lever to balance them out. If you want to move the bite across to the left hand pad, put the screwdriver behind the right hand piston, and vice versa.
