bleeding the breaks, what is with that little hose that spit the fluid out all over

[Mike Kast]

Thank you everyone who helped with the disk job. I love this site.
I used the little pressure tank to bleed my breaks. I cleaned it out filled it up with pretty blue racing fluid and started pumping.
It got up to about 5 lbs and I kept pumping since 5lbs didn't seem like enough. Then I heard the dripping...AAAAAAAAAAAAHHH!!!
I must have had a cup of pretty blue fluid on the floor, dripping all over the underside of my car AAAAAAAAAHHHHHHHHHHH!!!
My poor daughter was standing there just chatting away at a million miles a minute. I kept as calm as I could.
"When are you gonna be done Dad, When are you gonna be done Dad, When are you gonna be done Dad, When are you gonna be done Dad"
AAAAAAAAAAHHHHHHHHHHHHHHHH!!!!

Well... I found a funny little hose with a bolt clamped in it that fit right over the hose that was leaking. I was wondering why it was in that little pump tank when I cleaned it.

So I guess my question is, if someone would be so kind to answer, How much pressure do you need to put in the tank after the little hose is blocked off? What exactly is the that little pisser hose there for? Does anyone have a not so messy procedure for bleeding this way? I still have new rear rotors to do. But that will be after I enjoy my new front ones for a little while

Thats me in the break fluid

That little hose is the over flow for the brake fluid resevior. Before you pump any pressure to the system make sure you clamp the hose at the resevoir. I too found out the hard way.

I too found out the hard way about needing to clamp that hose. What a mess!

You don't need a ton of pressure on the bleeder. Start with 5 psi, then if there isn't enough flow, increase it.

Mike,

I don't think there is a back yard mechanic on this board who hasn't found that out the hard way.

It's a little late, but I am afraid you might have wasted that pretty blue fluid. In my car, you have to disconnect the rear brake lines to take off the caliper. The brakes are attached with 2 screws and just slide on the rear hub.

Actually this board sucks... the wallet dry. The people and search function on this board make just about any job possible if you have the time and the patience.

wow.........i wasn't going to say anything because i figured it out but.........
i just found out what the little hose is for about 20 minutes ago
spent the last 20 minutes cleaning up the mess
small world.........

There are instructions on the bleeder. One of the steps listed is to hook up the bleeder without brake fluid in it and do a pressure test to see if there is a leak. If people would do this, they would find the overflow line before they dump a bunch of brake fluid down it. Jim

That brake fluid will eat paint if left on for very long, make sure you get it all cleaned up as quickly as possible.

Time to make sure the overflow hose which runs through the left fender and inside the trunk hasen't cracked. Since brake fluid is hydroscopic, you might be able to clean it up with water if it hasen't gone through the paint.

[Mike Kast]

My bleeder came with the car. I got an overview from Leland, the previous owner, about how it works. The overview unfortunately didn't include the overflow tube. I cleaned it up as fast as I could with water. Why the overflow? Is it in case your brakes are so overheated the fluid is boiling over? Does it expand?
Anyway... My brakes are incredible now. My car is 40 miles away from 230,000 miles and stopping on the dime!

[bell]

yea i was in there with a roll of paper towels and parts cleaner.........
and a manual to the bleeder? what's that?

[Jim Sims]

I'm assuming we're talking about a Motive Products power bleeder. On Decal, on side of bleeder, step 4: Tighten pump cap onto empty Power Bleeder and pressurize to 10 psi. Check for leaks at fluid reservoir and at Power Bleeder hose connections......... Jim

Mike - just a thank you in advance. I reinstall my calipers next weekend and will be pressure bleeding. I would also be cleaning up brake fluid were it not for this post.

[Mike Kast]

ohhhhhhh... right on the bottle...You'd a thunk I'd a looked at the thing wouldn't ya!
Look Jim, your an engineer. Have a little sympathy for the brain dead among us. Or the fact that I have to live this way!

[Mike Kast]

that was a joke Jim...

[Jim Sims]

I've also spilled blue fluid on the floor through a set of rotten reservoir line rubber bushings on the the top of the master cylinder. The system held pressure for a while and then started leaking when I began bleeding! I just got a little further into the process before I made my mess! I had to stop and finish the next weekend when a new set of bushings came in from Pelican. Learned how to take the master cylinder out too. Cheers, Jim

uhggg... thats even worse, that brake fluid is some amazing paint remover.

Sheesh!
Seems Lee gave it all away.
What caused him to lose his mind?

I think Jim is trying to make up from Warren's absence

I have done the Power Bleeder overflow trick. It's easy to forget.

I don't think that bleeder fit on the Z350.
He did give it all away though. I got all the factory manuals and 6 books besides 3 oil filters a new belt, some tools, new cap and wires, a bag of fuses... all sorts of stuff I haven't even sorted out yet.
I think I got a real good deal but there is a few things I'm discovering that are quite mysterious. I'm sort of on the fence about bugging him too much though. He sold the car and it's out of his hands now. It didn't come with a warrenty

I realized that this board is almost a better version of Carfax...

you could search for all of Lelands posts...which are ALOT, and get a good blow by blow history of his car...
