Brakes stopped working

[Tokyo_Drift]

So I'm driving, car seems fine, I go to pick up my friend, and pull over. All of a sudden, my brakes are gone. The pedal has no resistance on it, and nothing happens when I push it, unless I jam the pedal to the floor, and they somewhat work.


WTF is going on, it was scary as shit trying to drive without brakes. What should I check

there's air into your brake lines, u have to purge your brake fluid.

air in the lines, or master cyl is shot. does the pedal return by its self it not its a booster issue, but propably either air in the lines or master cyl is dead

Yeah the pedal returns by itself.

Did you bother checking your brake fluid reservoir?

Just did, it was like 4 am last night, so I didnt bother.

But Yeah, its pretty low.

Isn't a dash light supposed to come on for low fluid? Anyway, add fluid and test brakes. May need to bleed air from the lines.

BTW...why was it low? Brake fluid doesn't just disappear. Sounds like you should have the whole system checked for a leak.

dash light comes on when its like almost out with 1/4 in of fluid it should be off but 1/16 it comes on i think

My light is on, but I assumed it was for the parking brake sensor, so I never worried about it.

But yeah, I put more brake fluid in it, and it didnt change a thing.

rebleed it. and see if not its the master cyl

i had the same problem and it was my brake booster. when you step on the brake, do you hear air leaking from somewhere behind the steering wheel or atleast some where around that area? Because thats what i heard and it was my brake booster

 

[Samurai_Blue]

the pedal returns on its own power, the booster is working. Its mostlikely the master cylinder

 

[Tokyo_Drift]

I don't have a clue on how to bleed brakes at all. I'm kind of an idiot when it comes to anything mechanical

 

[Samurai_Blue]

jack up your car. undo the bleeding valve on the rear right caliper pump 10 times and hold it 3/4 down and have someone open the bleeding valve and then do it until theres no air. then repeat on the rear left side then the front right then front left. it should go in a backwards z pattern. it takes 2 to do this.

 

[Tokyo_Drift]

Alrighty, and what about how to check the master cyl?
