i replaced the only things wrong with my brake system and that was rear right wheel cylinder and master cylinder. i just did the master cylinder tonight; bench bleed it, then bleed all the wheels, i go to push in my brakes and it STILL goes to the ground

the only things that could be wrong now is either a leak(which is nearly impossible since ive checked all over multiple times) or there is air in the system which i dont understand since i've bleed everything two different times.


i guess im asking if im missing something abvious that would cause this. please help me.


oh yeah, 91 civic dx, all stock brakes.

 

are u loseing fluid in the mastercylinder?

 

vaccuum bleed the system.... if that doesnt work you have a problem elsewhere... IE brake booster

 

i dont think so. how would i check and would it do that on a new master cylinder?



and to the second response, would the brake booster have to do with no pedal pressure?

 

If you have anti lock system, it could be the air is in the system. Honda has the gear to deal with a complete bleed but you can do a decent job yourself by slamming Hell out of the brake pedal to push the air out to the wheel cylinders.
If those are year drums, be sure you adjusted them out by reverse gear braking.

 

U dont think your new mastercylinder is loseing fluid, or have u checked?

 

try returning the master cylinder. I know it is new but, it has happened to me before several times. I just recently had a 93 ex that I had this problem with.

 

mine does the same thing and i actually replaced the same things you did with the same results. but im putting a new booster on today. will let you know what happens

 

im with insaneciviccoupe, i think a good bleed would fix ur prob.

either way, g/l!

 

i guess ill bleed all of it again............................................. ....................and again
