First I just want to confirm that the connector that clips into the harness under the brake fluid resorvoir tank is indeed for the brake fluid level sensor. If that's correct then what would be the consequences of damaging that connector? I was bleeding my brakes today and I accidentally poured a little too fast into the reservoir and a bit of fluid spilled out where some got onto the level sensor connector. Some fluid actually got inside the connector so I had to unplug it and clean it as best as I can. Now my brake pedal travel is really long, not quite to the floor but getting close, and I can't even engage ABS when I stomp on it all the way. It's like I have to do twice the leg work to make the brakes engage sufficiently. I'm thinking I must still have quite a bit of air in the system and I just need to bleed again. But could a damaged fluid level sensor in some way contribute to what I'm experiencing?
Even when I press the pedal down all teh way at 100%, ABS does not engage and my brakes don't lock up. It feels like I've actually lost the ability to produce as much brake torque as before and my stopping distances are longer. Braking jsut feels very weak. Bascially, I would not want to be in an emergency braking situation because I know my car will not stop in time. I'll rebleed tomorrow even more thoroghly and see what happens.
I don't think the fluid level sensor has anything to do with what you are experiencing. Are you an experienced "brake bleeder" ? IE did you follow the proper procedure to ensure no air got in ?

Yeah, I've bled my brakes on two different cars for about 8 - 10 times now mainly for track days. This is the first time I've encountered this problem. For background info I'm using speed bleeder screws which allows the one man bleeding. The first few times I bled brakes I did it the old fashion two man way. Ever since I've been using speed bleeder screws w/o a problem until now. I'm sure I messed up somehow so we'll see.
Let us know how you fix it as I'm considering the speed bleeders. I have read mixed reviews on them. Some like them, some don't. Not sure why they sometimes work well and other times don't.
So I rebled again today but this time I just did a gravity bleed which takes a long time. Apparently two of my speedbleeder screws are deffective as they let fluid out just by opening the bleeder screws even though the checkvalve is supposed to be closed. So I did a gravity bleed on these two screws. The other two didn't let anything out until I actually pumped the brake pedal so I think those are okay. After taking about 2 hours and using about 24 oz. of fluid my pedal is much better now and firm. After doing some research, it seems like defective speed bleeders aren't uncommon.

yes, that is the brake fluid level sensor. I just purchased this single part from rock auto trying to see now how to actually remove it from the plastic casing to replace just that single part.

Kudos on actually posting the SOLUTION to your brake issue. Many threads like this go unanswered because the OP realizes they did xomething wrong and are too embarrassed or lazy to finish the tread properly by posting the answer. Good on ya for letting us know about the speedbleeders!
