Well heres a little story for you guys.

driving around in my car. everything is fine. pull into a parking lot. shut her off, go inside whatever establishment i happen to be at, come out, start my car then go driving. After driving for a little bit i come to a red light and hit the brakes, as any normal person would and what do you know i have no brake pressure. so i pump it once and brake pressure is back. Strange, i think to myself. get home. shut it off and go out again later and everything is fine, until i shut it off again and then turn it back on and go driving. not sure why its doing this i figured it was because my turbo is heating up my brake booster so i thermal wrapped my exhaust and what not and it still does it from time to time. i topped off my brake fluids, checked my lines. so im 100% confused and i am now turning to TR for help.

Lemme know what you got.

bleed em...

 

Allrighty. thanks.

 

lemme know how it goes... remember, start with right rear, the left rear, then right front, and finally left front...

 

Should have hit me up!

Most likely air in the lines working itself around the braking system.

Call me if you need a hand bleeding them.

 

Bleed them, maybe replace the check valve, and last resort, replace the master cylinder.

 

more than likely, it is air.
There are other possibilities though...

bad booster
bad check valve
water in the fluid
a caliper that is partially seized and rubbing the rotor getting really hot and boiling the fluid.

 

But wouldnt a dieing caliper cause the brakes to make a terrible sound as it rubs?

 

just bleed it out with new fluid problem should go away

 

check for leaks everywhere?
could also be a internal leak in the master
