Brake pedal grabs real low, bench bled the master, bled all the brakes, no leaks, no air bubbles. WTF is up? I can't figure out what else could be wrong? Its a brand new master cylinder and brake booster. The booster works because the idle changes but with the car on the pedal sinks even worse.

did you start the car up ?

probably still have air in the lines. its not an easy task to do.

+1 for more air.

You will get a bad Master cyl from time to time out of the box, if you did all that you have said it could be a bad one.

I started the car up and when I did the pedal was super soft and it would was real easy to push right to the floor. The brake booster is workign because the idle changes but the brake still grabs low. Should I just kep bleeding for hours? lol Seriously its ridiculous. Ive done each caliper about 10 times or more and its still a nice steady strong stream or fluid. A bad master cylinder though the pedal will be firm and then sink when you keep your foot on it. This isnt the case here. Every part seems to be in perfect working order but something is not right for sure.

does the pedal build up any kind of pressure with the vehicle off ?

FoxHondaRider

you can pump it all day and it will do the same thing each time. It doesnt build pressure like it should with the car off. The pedal remains consistant and doesnt change. I honestly dont know WTF is up. Ive asked several mechanics and they told me I have done everything correctly but have no idea what the problem might be.

Return the master cyl and get a new one.

Easier said than done, its a 97 ITR master.

omgwtfbbq!

yeah if you don't get pressure with the car off and its not leaking i'd say the master is bad.
