HELP: why are my breaks not working?!

Question

Audi A6 1997-2001

La seconda generazione dell'Audi A6 venne introdotta dalla casa tedesca Audi nel 1997. La prima novità di questo modello fu la nuovissima piattaforma Volkswagen Group C5, offrendo un desgin completamente revisionato e sospensioni sviluppate di recente. Poi ci fu il nuovo cambio automatico tiptronic a 5 rapporti come optional.

HELP: why are my breaks not working?!

I have an Audi a6, year 2000. My breaks were locking up every now and then and my break pedal was super tight. I did some research and found that i had to replace my abs sensors. I did that and now my breaks are acting the total opposite. My break pedal goes all the way to the floor and it is hard to stop my car. I tried to bleed the breaks but only two of them actually bleed.

could this be a blockage issue?

if so i feel like the blockage would cause my breaks to be hard such as too much pressure...

could it maybe be the master cylinders?

or did i just mess up my abs somehow?

Did you replace your wheel speed sensors or your ABS module?

Speed sensors are in no way related to the hydraulics of your brakes. If you replaced your ABS module/hydraulic unit then the brakes will need to be bled through.

Are you unable to open the other two bleeders or does no fluid come out? It's possible that the bleed hole is plugged up of the rubber caps were missing.
