so i have a 96 ex sedan and the brakes went out. i was just driving normally and i lost all pressure in the brake pedal and had to use the parking brake to help slow down. if i pump the brakes i get pressure back but not for long. my original thought was i had a leak but i couldnt find any and my master cylinder was full. so my next thought was either my proportioning vlave (if equipped i dont remember what valve is used for my brake system) or the master cylinder. i replaced the master cylinder and bled the brakes and it got a little better but the brakes still dont apply till its about an inch or 2 above the floor and they dont apply hard either. i did a brake service about 6 months ago where i flushed my brake fluid and replaced my rear brakes. this problem has me running in circles. any advice or tips would be greatly appreciated.

I have a feeling there's something wrong inside the proportioning valve.

I'd replace it and go from there, I'm pretty confident that will solve the problem because it needs to be something that affects all the brakes.

yea thats why i was thinking the master. but its been so long since i had brakes class that i dont remember what the valves do anymore haha

Change the valve and definitely flush the system more often.

Wilwood makes cool adjustable proportioning valves, they're cheap too, like $80.

i flushed the system about 6 months ago the fluid is spotless and i will look into those valves

You dont have a "swooshing" sound inside the cabin do you? It could be a sign of a broken brake booster.

i dont have that sound in the cabin and ive thought about the booster but wouldnt that make the pedal hard? i think i might have air in my lines so im going to do a complete fluid flush soon but if that doesnt fix the problem then i am stumped
