Default spongy brake's....need input

alright so.........when taking a long stop, you know, slowing down from 55 to a stop... my brake pedal will actually go all the way to the floor, or when at a stop light, waiting for the light to turn it will do it then as well.It's been doing this for a while now, and have finally gotten the fund's to actually do something about it, here's what i've done recently

new(re-furb) calipers on the front both side's as well as pad's
new wheel cylinder's for the drums, both side's as well as shoe's
bled the living hell outta the line's

the front rotor's still got a lot a life on em, and clyde an matt will tell ya how much fun it is to replace the rotor behind hub assembly on the accord's, so i'm not looking into doing that as of yet.

any in-put would help, i was thinking master cylinder, but from what i've been told, is when that goes out, it's harder than hell to push the brake's.
brake fluid is full....input????

i agree with Pata, brake booster first then the master cylinder, it sounds to me like you dont have enough vacuum being produced my the booster.

And yes, pressed on rotors are a pain in the living ass...

Default spongy brakes

its definetly not your brake booster. this a simple problem of air in the system,or the seals in any of the cylinder's or a leak in the line. check your system from back to front. start at the rear cylinders check for fluid leaks also check the wear of brake shoes or pads, then move to the front and conduct the same check. if you dont find any signs of a fluid leak or wear of pads, then go to the master cylinder and check for fluid leaks there if there are none it is safe to say that the seals on the piston in the master cylinder are worn and you are loosing presure and introducing air into the system. let make it clear that if you brake booster was failing you would find it very hard to press the brake pedal because it asists with pushing the pedal that moves the piston in the master cylinder, simply the brake pedal would feel very hard. these simple checks could save you alot of money instead of changing things that dont need to be changed.

your master cylinder is worn out and needs to be changed. when your master cylinder is gone the car doesnt stop it slides and the pedal will travel all the way to the floor

PROP'S TO BAHAMAS!!!!!

ran over to napa to pick up the master cylinder, called ahead, they told me it was gonna be like 70$, just as i was walking in, i saw my cuz leaving his work(he works at a tire shop, so he get's discount's at napa) flagged him over, gave him the cash.....not so long story made short...ended up paying a lil over 50 for it!

got home, drained my old master wit my mighty vac
http://tasauto.com/Product/Browse.aspx?d=710&p=2
(scroll down)
then drained the lines...(wit the mighty vac)...the old fluid was so bad.....some of it was a milky color, other parts had a green hue to it
swapped out the old, in wit the new.
filled up the reservoir, started using the bleeder system, blah blah blah...ended up doing a gravity bleed after all that, an crap, brakes feel better than when i first got the car!
no more spongy brake's!!!
