Brake pedal firm, start engine, pedal to floor?

Short and sweet version;
-Replaced calipers and pads.(Front D-30)
-Bled all four corners.
-Pedal feels nice and firm.
-Start the engine and all pressure is lost.
-Turn off engine, pump pedal, pressure builds again.
-Repeat as often as you want with same results.

WTF?

Doesn't seem like a normal bleeding issue, since the pressure is there, and stays, until the engine is started.
The brakes were fine before I got ahold of them. Well, one caliper was sticking and the pads needed replaced, but no pressure weirdness like this.
What the heck did I screw up?

PLEASE HELP ME!!!! [img]/ubbthreads/images/graemlins/wall.gif[/img] [img]/ubbthreads/images/graemlins/crybaby.gif[/img]

Sounds like you still have air in the brake system which power bleeding or even gravity bleeding will probably correct.

Re: Brake pedal firm, start engine, pedal to floor

Why do I love my Short Wheel Base?
It reminds me of the bus I used to ride to school!!!!! [img]/ubbthreads/images/graemlins/thud.gif[/img]

Dale was nice enough to mention in a PM that it only felt pumped without the booster, and with it showed it's true colors.
It was in fact air, but it sure was decieving feeling SOOO strong without the engine/booster.
I guess you're never too old to be an idiot.
I should probably just delete this thread to save face, but I'll leave it and tell the truth of my idiocy so it might help another down the road.
I HAD THE FRIGGIN CALIPERS ON THE WRONG SIDES!!!!!!
There, I said it.
They say the truth shall set me free, but I really don't feel any better yet.
waiting....waiting....waiting.....
Oh well, at least it will be ready for Haspin Sunday.
Anyone care to join us? You can taunt me and pelt me with rocks and garbage if you show up.
Thanks for the help.

OK, but that's still cheaper than putting a pad in back-wards, that toasts a rotor.

Not me but one of my apprentice redneck wrenchers....

Glad it worked out.

Sunday is a maybe at this point.

Hence the phrase...."We learn by our mistakes, that is why we are all so bloody smart".

JB, you are more man than most to come clean so quick and honestly.....

At least you got off cheap on this one.....I'm sure there are a few of us who wish they (I) could say the same.

Re: Brake pedal firm, start engine, pedal to floor

LOL! Don't feel bad, not long ago, I was in a hurry, changing plug wires, rotor button, and distributor cap. [img]/ubbthreads/images/graemlins/spank.gif[/img]

Jump in, hit the starter, woww,woww,woww, nothing! No go, hmmm? [img]/ubbthreads/images/graemlins/confused.gif[/img]

Looked at passenger floor board for a second,(probably 5 minutes)! [img]/ubbthreads/images/graemlins/laugh.gif[/img]

What the f...? [img]/ubbthreads/images/graemlins/frown.gif[/img]

Then suddenly out of the floorboard, a little voice screams, hey idiot!(Idiot being me, of course, HUH?) [img]/ubbthreads/images/graemlins/shocked.gif[/img]

I see the rotor button is laying there in plain sight! DUH! [img]/ubbthreads/images/graemlins/mad.gif[/img] [img]/ubbthreads/images/graemlins/cussing.gif[/img]

Hey, and I ain't even blonde. Go figure! [img]/ubbthreads/images/graemlins/40BEER.gif[/img]
