'90 Accord EX
 

I bought my car about 2.5 yrs ago and it has broken down a few times,
mostly suspension parts needing to be replaced and it has a bit of rust in
the "honda spot" but thats about all that is wrong with it. It has been
very reliable and nice for $1780 and I bought it with only 97,000 miles on
it. The clutch has been nice to me considering I beat the out of it
too. haha...

About a month or so ago, I started experiencing a loss in brake
pressure at the pedal for some reason. I will be sitting at a stop light
and the pedal will slowly start sinking in under the pressure my foot
supplies. Does anyone know anything about what it could be. I would much
rather fix it myself then pay to have someone else over charge me for labor
to fix it. I was thinking it might be the master cylender, but I hope it
isn't. Has anyone experienced this before?

Also, does anyone know where I can get some factory specs on this
car, I want to figure out what kind of gas mileage I should be getting with
it and other things.
