    Default problems with my brakes

    okay well i got a 1994 acura integra gsr. i had a problem with my brakes. they were super soft whenever i stepped on them and then they would drop on the floor. so i decided to bleed them. well now they're more stiff and firm but if i hold the brakes for awhile, they still fall down to the ground.

    can anybody help me out with this?

    is it the master cylinder?

    or is it the brake booster?

    or could i have a leak in my lines?

    continue bleeding the brakes if you got results. It can take a long time to remove all the air manually.

    If you want to just get it over with, take the car to a brake shop and ask them to bleed the brakes with a machine... probably charge you 40 bucks, and save you a ton of time.

    By there being brake fluid all over the wheel?

    Changing the master cylinder does not mean the master cylinder is good.

    Try bleeding the master cylinder. Most case alot of people tend to forget to bleed the new master cylinder before the installed

    take the brake lines off the master cylinder!

    Install either plugs,bolts into the master with the right thread pattern to block it off... then mash the brakes an hold if they leak down still its the master cylinder,. if not then you might have either vaccumn issue, or a rear brake leaking... LMK if I can help
