It depends on the condition, so you have to "open up" things first. Best 
bet is to work in pairs, either front or rear. I think you said your front 
wheel leaks, so your car dictates starting first on the front pair of 
wheels. You have a dual master brake cylinder, look for the "F" or "R" 
stamped below each brake fluid bowl on the master and just work with the 
"F" one first.

Again, it depends. Don't yank off everything. Start with one wheel. If you 
get confused with how the parts go together, then you can compare with the 
other still-installed side. The exception is if the slave cylinder(s) on 
one side is/are really screwed up, then it's almost certain that the other 
wheel is just as bad (since they share a common master and the fluid).

Get the parts from any of the roadster vendors. We've got a couple local 
vendors in the Bay Area where you can pick up the parts. Before starting your 
inspection, it doesn't hurt to pre-buy the brake rebuild kits, as they are 
relatively cheap and you'll need them someday anyway. The other brake 
components are expensive, so buy them as needed after your inspection. Buy 
lots of brake fluid from the local auto store.

I've got a web link for the rears, nothing for the front as yet.

http://www.2xtreme.net/fredkatz/brakes1.html

The rears are really easy to take apart and reassemble. The front is a little 
more complicated, but easy to master. Loosen the lug nuts. Jack up the front 
and put it on jackstands. Remove the wheels. Crank the steering wheel so you 
can reach the 2 bolts holding on the caliper assembly. Drain as much fluid as 
you can from the "F" side of the master cylinder at the firewall. Put a catch 
basin under the caliper assembly, and remove the hydraulic line between the 
caliper assembly and junction block. Important - use a marker to note which 
side is up and what side of the car it's on. Use a breaker bar to remove the 
2 bolts holding the caliper assembly. Check for thin washers behind the 
bolts, don't lose them! (Critical for alignment.) Now slide the entire 
caliper assembly away from the disk rotor. Simple!

Now re-attach the hydraulic line to the junction block. Loosely mount a 
C-clamp on the caliper closest to the junction block. Put the caliper 
assembly into a bucket, and cover with rags to prevent splashing of brake 
fluid. Gently pump the brake pedal until you hear a "pop" in the bucket. You 
will see that one of the pistons popped out of the caliper. Now you can 
inspect it to get an idea of how bad off it is. To do the other one, take off 
the C-clamp, remove the crossover line between the caliper halves, and plug 
the open fitting and again gently pump the brake pedal to "pop" the remaining 
piston out. An alternative method is to use an air compressor (with very low 
air pressure, 3 to 5 pounds).

Not at all! We all had to go thru this the 1st time. Just don't take off 
more than you need to, keep it manageable, and document what you do (easy 
to forget how something came off). Use safety goggles, protect your paint 
from brake fluid. The important thing is to do the brakes right the first 
time. If not, the problems will come back fairly soon. And a lot of us have 
had to do our brakes over again (me included).
