Abs booster goes off at low speed stops

Does it look like this?

 

It does not...let me see if I can find a picture off the internet...I am not currently able to take pictures. Something is up with my phone. I could try with my computer though. Here is something very close to what mine looks like-

 

Can you find this part on yours?

 

Yep, I've got that tube.

 

Disconnect the tube and pull out the part which the tube was connected to, then try to blow through the part. You might need a flat head screw driver to help get the valve off the booster.

 

Will I lose any brake pressure with it off?

 

Sorry, I just realized the the picture @des2mtn sent me at first would have worked :l

 

As long as your engine is off, you're fine.

 

I pulled the hose off and there is a black tube...do I blow into the black tube or is there a piece that comes out for me to blow into?

 

Pull that black tube out or twist it out, then blow into it. You might need to use something like a screwdriver to pry it out. If I'm remembering right, it comes out pretty easily.

 

Doesn't sound like it. I'm on the vacuum bandwagon for this new issu3.

 

It did come out easily. I will go do that real quick.

 

Found it.

 

Blow into it on both sides, you should only be able to blow air through one of the sides.

 

Okay, I blew into it. I can only blow into one side...I think it's tight like it's supposed to be.

 

Alright cool, go ahead and re-install it and the hose, then I'd try following the troubleshooting from the manual above.

 

Thanks for grabbing that FSM page!

 

Sounds good! Thank you. I will update with results.

 

I could not get the brakes to fail any of these tests...

 

Would the guys working on brakes had in any reason to mess with the brake pedal return spring or is it worn out ?
If as you said you can pull it back up then it might be spring

from 06 FSM....

 

I had new brakes put on in December...and nothing was wrong with the brakes afterwards...reason for new brakes was because of both front rotors being warped. It did not have the problem when the shop had it in, and then I got it back and the problem developed. I don't know how it could have worn out the spring, as it worked fine when I dropped it off. I got it back and the pedal wouldn't come back up. I'm thinking that it could be the spring though as the shop was working under the dash (I presume) with their scanner. How easy is it to replace the spring?

 

First thing I'd do is do a visual inspection of the spring.

Do you see it installed?
Is it attached at both ends?
When attached, if you push in the down no more than 1"-2", does it seem to act properly?
When detached, if you can easily detach it, does it appear stretched or worn?

If the answers here are YES, YES, YES and NO, then I doubt the spring is your issue.

I'll be honest, without actually seeing this w/my own eyes, I'm having a hard time visualizing and giving suggestions.

 

Let me go do that check. I am able to take pictures now…let me know if you need me to take any pictures and I can do that. I appreciate your efforts a ton @Shifty !

 

I doubt the spring is my issue. There is no issues with the pedal returning after 1-2 inches of travel. Here is a picture of the underside.

 

I'm not seeing the spring, am i blind or is it missing?I see it on e-brake, shouldn't it go into empty hole on upper brake pedal and back up in towards dash?
