Thread: Brake failure

I need help peeps. My brakes failed last night but i cant pin point the problem. There are no leaks but the pedal is super soft. Any ideas what it could be?

blown master cylinder, or a blown piston seal. Pump the **** out of the brakes and see if your fluid is going down.

If the fluid is lower there is no doubt its a burst line, seal, or mc.

But if anything was blown wouldnt you see a leak somewhere.

Did you look under the carpet by the pedal for fluid?

doesn't necessary have to leak externally as I have seen master's go and the fluid say inside.

Generally when MC's go they don't leak out where you can see it.

I have witnessed more then a few go in my day and none of them were leaking.

The first time my old original mc went I thought the car just needed to be bled. After bleeding the brakes for 1hr I finally said fu*k it and got a nx mc, fixed the problem immediately.

Also when the piston seal goes it can cause the dust boot to fill up with oil and prevent an obvious leak but bubble up and cause the pedal to feel terrible. You should notice a decrease in oil if that were to happen.

That is exactly what it was. The passenger piston seal was bad. But this is were im lost, there was absolutely no pressure in the pedal and on top of that all the fluid was gone with no signs of goin.
