Something up. After taking the rear calipers off yesterday to paint, all the brake fluid pretty much drained out. I put them bake on, bleed the brakes, and refilled the reservoir. I noticed yesterday in the driveway they were quite sponge like. After doing the fronts today, let the caliper on, I bleed all again and refilled more. Now I was going to a drive, and before I left my street I couldn't stop the car. What did I do? Has to do something with the rear lines to the rear calipers I believe.

So I jacked the car up again. I took calipers off by its two bolts. I pushed in the brakes and the pads touch, therefore the piston is working. However, I am not sure if I assembled this part correctly. There is a copper like washer I put on the inside of the brake line, on the bolt. Not sure if it goes there or near the head side of the bolt. And I also am not sure if the brake line is supposed to go this way on the caliper or be flipped 180*. I tried 180* when I installed and it didn't want to go so I think this is the right direction. Now that washer could be screwing things up.

Did you bleed the calipers furthest from the master cyclinder first.(RR first, LR, RF, LF) If not, you might still have air in the lines.

Yeah did that twice.

I'm trying to think, I haven't done anything with the calipers on the GP yet, but i'm thinking there might be some kind of o-ring when taking off the calipers (where the line connects to the caliper) on some cars, I might be wrong though.

There is a metal ring, I did put that back on though. Just slides over the bolt threads.

IDK then. Maybe have someone look at the calipers while you pump the brakes and look for leaks. I can't image you damaging the brake lines that easy unless they are rusted. Maybe the master cyclinder is locked-up or something

You didn't accidently let the brake resevoir empty while bleeding the brakes did you.

No, but it was empty when I took the rear calipers off.

Huh, I would try bleeding them again, and see what happens. Might have to invest into some speed bleeders. haha

Any help?
So I looked at the front brake line and it looks the same. I just not 100% that the washer is in the right spot. But when I took it off that I tried to make sure where that washer went.

When I turn the key to accessory the brakes are firm. Once I start the car up and push the brake in, it goes to the floor without resistance.

There should be two copper washers. One goes under the block, one goes under the bolt. They're there to prevent leaks. If you don't see any leaks, they're fine. If it's spongy, you've still got air in the system. When I removed my master cylinder, I went through half a quart bleeding the brakes. If you drain a caliper, you'll probably need to use more... calipers can retain a lot of air in the cavity behind in piston. You might want to let someone tap the caliper with something while it's being bled, to get any stuck air out.

The only other thing I can think of, is gunk from the reservoir has somehow got in the lines, maybe even ABS module, and blocked something. But if fluid comes out when you bleed it, it should be fine. Your issue is really weird.

Alright, thanks Rook. I figured you would help chime in. I bled the back decent. I may try the front again.
I tried it again. I just don't get how I got pressue on the brake when car not on or car is in key on, but no pressure when I have the car running. If I know what's wrong I can fix it. I just don't know what is wrong here.

I think I remember seeing that the ABS module will bleed itself after a few starts. Perhaps it bled itself after you started the car and introduced air back into the rear lines? Just a random thought.

Hmm...interesting. I did notice brake fluid this morning near there and on the ground, transmissino, and what not. I may try to get a big bottle and do a large bleed session this afternoon, then if that doesn't work, take it to the mechanic some how.

"When I turn the key to accessory the brakes are firm. Once I start the car up and push the brake in, it goes to the floor without resistance."

That would be your vacuum booster (The amount of pressure required to stop a car is excessive so cars have a vacuum asisted booster to help you stop the car..its like having a hydraulic jack compared to a sissor jack..that much easier)

Those copper washers are called "crush" washers and 90% of the time are a one time use deal. Once you "crush" them on to the caliper, they mesh to the contours of the surface, trying to reuse them can result in brake failure. If you resued them, you really should get some new ones (very cheap at the parts store).

99.9% sure you have auir in your system though. You need to open all bleeders (with containers under each caliper to collect runoff fluid) and just keep the master cylinder full of brake (dot 3) fluid for a bit.

best way is to have a friend in the car as you go to each wheel (general rule is to start with furthest wheel from the master cylinder), have that person gently push down on the brake pedal as you open the bleeder (do not have them push all the way to the floor or you may ruin a seal in the master cylinder, have them push to 75% of the way down), then you close the bleeder, the person in the car lets up on the pedal, repeat a few times, watching the master cylinder to make sure you are always at least 1/2 full..go to each wheel and repeat, within a 1 or 2 passes of all wheels you should have a killer pedal, if not, you have a leak somewhere (and you will know if this is the case as you are bleeding each wheel).

I have installed probably 3000 sets of brakes in my life and have never had to bleed the ABS..never...so don't go loosening those bleeders, that may cause you a TON of problems and you willbe at the dealer going "uhmmm...."
