Since it's a new-to-you secondhand bike, for safety's sake as well as to deal with the sluggishness I recommend you take it to a bike shop for a complete overhaul. I'll bet you'll be astounded at the difference when they're done.

The most common way is to use a "Chain Wear Indicator Gauge" tool. (google for product pages). If you don't have access to (or don't want to buy) one, you can use a ruler: http://sheldonbrown.com/brandt/chain-care.html

Rust on the surfaces of the pads & disc could cause extra wear & noise, or if bad enough reduce the effectiveness of the brakes. If there is enough present that you can see residue on your finger after rubbing the surface, I would suggest cleaning with a stiff bristled brush or a kitchen scrubber & isopropyl alcohol (some people have recommended ...

I think the rust on the pad surfaces will go away on its own when you use the brakes. It's probably just a thin layer on the surface. I don't think it hurts the brake disks, since rusted metal is softer than the original metal before rusting. The rust on the backing material probably doesn't matter much either, since you were still able to remove the pads ...

If you clean the pads with some brake cleaner and a brush and they just look rusty, it's not necessarily a problem provided your brakes are grippy and effective. If clean them and replace any bent discs and your problems go away, you're probably safe as long as you keep a close eye on things. In other words, if your brakes are grippy, quiet, and smooth, a ...

Rust or other build-up on your pads is not an issue if you have enough surface left. Depending on the bran 1-2mm on either side is plenty. If your brakes aren't biting properly clean the pads and rotors with rubbing alcohol. Use an old toothbrush for the pads and a clean rag for the rotors.

I think that with a well-running bike you ought to be able to do three things: The wheels ought to spin -- life each wheel in turn off the ground and set it spinning with your hand: it ought to spin and spin and spin almost without ever slowing down, almost frictionless The tires shouldn't absorb energy -- that means you don't want knobbly tires because ...

At a minimum lube the chain and see what is scraping. For the brakes just hold the bike up with one hand and spin the tire. Visually inspect if the rim is rubbing on the brake. Some times you can just adjust the brake and some times the wheel(s) need to be trued. Some times you have the tire rubbing on the brake. At this point need to decide if it is ...

First thing you can try is to disassemble and grease the bearings with the proper stuff. To do that you have to do the following: 1) Disassemble them as unscrewing the cones' contra nut and the cones themselves. 2) Wipe the old grease with something ( I am doing it with toilet paper ) 3) Wipe every individual ball of the hub. 4) After everything is clean, ...

I have some entrance level Shimano hydraulic brakes (bl-m445; br-m445) and while trying to bleed them, I accidentally overtightened the bleed nipple thus resulting in the threads being busted. I put some teflon tape on it and reinstalled it in the caliper, then resorted to burping the system. Although it took a while (max 15 mins) I managed to get from ...
