check your fluids.

if your not losing fluid i would suspect mast cyl. is losing boost. aka get a new one :-P

if he was loosing the fluid, the pedal would be on the floor all the time.
it is your master cylinder.

damnit....Thats what I was thinking.. The fluid is fine. what kind of job am I looking at here?

I bought a brand new (not rebuilt) M/C at a local auto parts place for $65. It takes about an hour to install and bleed all the brakes.

You will notice when the M/C starts to go that you will have decent pedal when the car is cold, but then when it gets hot, especially on hot days, the pedal starts going to the floor. I am on my third M/C now. They seem like they last about 90-100K miles.

I've had mine for 230,000 miles

why dont you just change the "rubber things" (dont know the english term for them ) in the main cylinder? that would cost you 2-5$ and a 1/2 hour work. that's what usually goes wrong on the brake main cylinders

one additional thing though...when you bleed the breakes...make sure you don't step on the breake "all the way"...there is usually some rost at the end of the main cylinder ....step on it to the 'half way' when you bleed the breakes

well...the cylinder has two pistons inside (one for each circuit)...each piston has 2 "rubber rings" on it (help me out guys ...what's the name of those? ..)...the idea is the same as in a bicycle pump (open one and you'll see what i mean). Where i leave, there are 'reparation kits' available for master cylinders...cost 2-5$ and it's fairly easy to change (the most difficult is to remove the cylinder itself)
