I was trying to bleed the master clyinder on my 1998 Chevrolet(2wd) S-10 LS 2.2L MFI (ABS Kellsy hayes) after a nasty break line "rust through" and nothing comes out.
I reset the combination valve, I have fluid in the master cylinder--although it went dry after a nasty break in the line--and can't get fluid to the back wheels.
Question: on my master cylinder there are two brake lines going to the abs system, if you are looking from the front of the truck to the back, then the front line controls the front breaks and the back line controls the back breaks, right.
A). there is no fluid coming from the front break line when I bleed the master cylinder(mounted on the truck) but there is fluid coming from the back break line. HUM???????
But, I have front brake fluid spurting out when I bleed the front breaks but nothing will come out of the back breaks?????
I'm stuck on this one.

The best way to do this is with a pressure bleeder. It is possible that when you bottomed out the master due to the leak, that the seals got pushed through some rust and corrosion in the master and tore the seals. That would mean you need a master now. You still may need a pressure bleeder though. I use one all the time and it makes bleeding those systems real easy.

yea, I read you reply about the master clylinder "bottoming out". That might be the problem but the pedal will hold the front breaks and not bleed down, that pedal is firm.

I have tried putting a vacum pump on the right rear bleeder valve and evacuating the whole system, but Nothing comes out--no fluid flow to the back wheels

You can easily lose one side of the master and not the other.
Vacuum bleeding is not the same as pressure and does not get the same results.

Today I put on a new master cylinder on, all seems to be well at the master cylinder.
But, I still can't get the combination valve to stay open long enough to bleed the back brakes, still don't have any fluid coming out of the back.
I made a custom tool to hold the combination valve open, I'll try to use it tomorrow.
So, who does the pressure bleeding, Dealers, Local guys. . .I have never seen anyone around here do it.

You shouldn't have to worry about that valve. Try opening the rear bleeder and lightly hold your finger over the end and have someone else slowly pump the pedal continuously. Just don't let it run out of fluid.

I tried to get my friend to pump the pedal easy but that valve just kept slamming shut.
Even when I tried it the combination valve would close, so tomorrow I'm going to use my new (homemade J-39177) tool.
After all of this, how much will it take to get some fluid to the back wheels????

I do a ton of brake work and I have never in my life had to hold that valve open to bleed. I use a pressure bleeder most of the time and have no problem at all. Have you tried bleeding the ABS unit first?

No, I havent' bleed the abs system at all, you are going to have to tell me about that.
I did, though, find a patch of gravel on the way to the store and stomped on the brakes.
Well, the ABS went on and the brake pedal went to the floor and I thought I was going to hit another car. Wow.
That was fun. I did get a bit better pedal for the terror. It seemed to improve the brakes.
That's what I call a panic bleed..........
Now about that ABS bleed.......................

Many of them have bleeders right on the unit. I just realized that one does not. I believe it can be bled with a professional scan tool though.

I can buy a small odbII scanner at sears, I was looking to get one anyway.
Any particular one, or reference manuals for the codes......
So, what would the process be.....

No, no, no...........
I said professional scan tool. That $100 code reader isn't going to do anything. What we are talking about is in the $5,000 to $10,000 range. The software update alone is over $2,000.

My unit does have bleeder vales on the front. I read that they require a tool, Like the J-39177
but I don't remember exectly what they were......" remove the three tools" is what the article said.

Good news:
Well, this morining I screwed on my homemade J-31977 combination valve bleeder tool and
finally got some brake fluid to the rear wheels. "spurt spurt". . . . . .
Bad news: the brake light came back on......which means that the valve went shut. . . .
I'll bleed it some more. . . .that might get it done.........
Hey, Hammer do those pressure bleeder push the fluid in throught the master cyl....and out the
wheel cyl. . . .is that how they work ???
Thanks Hammer, you are the best man, All of us rookies would be stuck without guys like you..if your shop was
in my neighborhood I would come by and drop a $20 in your pocket for lunch. That's what I do for all my local guys when
I need advice. For example, I gave Courtney at Somerset Transmision a big tip for cueing me into a problem I had with a plugged
catalytic converter. I went to Amaco and they wanted $1600 to replace the transmission. . . .Courtney told me to replace the
fuel filter and then unhook the exhaust system before the catalytic converter. . ..he was right. . . .

Yes, the pressure bleeder attaches to the master cylinder cap and pushes the fluid through. You just open the bleeders and let it flow until it flows solid and clear. It makes life real easy for a guy like me that works alone in the shop most of the time.
My shop is in the West Palm Beach area, right on the ocean. You certainly don't need to tip me though. We do this voluntarily and when someone like you actually appreciates the help, that's the reason we do this.

ABS on chevy trucks is a $150.00 pressure bleed job at the dealer, and $90.00 at the best local shop.
Now, if a guy had one of these he could do a little repair work on the side for all of his friends.

And, pay for the tool in about 3 months.

My snap on will do most of them and I rarely have to use it so I don't think you'll ever make you money back. That dealer is a bit steep there.
You also have to remember that when you bring something into a shop that you already repaired and you need their help to finish it, your lucky if they help you at all. they certainly aren't going to give anything away in that situation. All they want to do is teach you a lesson for trying to fix it yourself in the first place.

Well, I guess things in NJ are a little different.
For example, When I have a transmission problem I always take it out and let Courtney do the rebuild as a bench job, he's fine with that.
Pete, Garden State Truck repair, same thing, bad coil pack, he'll test it and I'll install it.
Vinny, at Hamilton Auto Body, I send him alot of work so he does a little welding for me.
Josh, at My Amigo Towing, if you don't want to do the job, go buy the part and he'll cut a break, "after hours".
Sammy, best brake man in town, neighbors (so I refinish the kitchen set for the wife, new Laquer and Veneer).
The thing is, you can't hound their time and advice and pay no tribute for it.
When they give you a fix and a diagnosis that works--you buy and change out the part and it's your labor--you gotta
go back and buy lunch or dinner on a big job.
It's always worked for me around here. . . I've known these guys for years and they still talk to me.. . . .

It's a little different when you have a personal relationship with them and have something to offer in return. I rarely know the people that try to do that stuff on me.

Well, I did the fiberglass work on a Ferrari for Hamilton auto body (Vinny), right.
They couldn't do the fiberglas work that I did, no one in NJ does it the way I do. Sh!t, Enzo couldnt' tell that I had been there!!!!
If I wanted, I could have had Penske's business in NJ for truck hoods. All of their fiberglass work on their trucks.
I know the regional manager in charge of Maintence. Because I could rebuild the nose of this car for $500 when they wanted $3000 for a new nose.
It let Hamilton auto body bring in the quote "low".
Plus, You should try to get guys in your "network" of associations. The Value is tremendous.
For example, you could have 20 guys walking around saying good things about you, "word of mouth" referrals.
You would pay thousands of dollors for that sort of "Public relations" at the media level.
Plus, It looks good when there are 20 guys "buzzing" around a shop and doing stuff.
The place looks "busy", "alive", "Viable."
Personally, Go out and get yourelf 40 guys that can say good things about you. Given these times of low income, and bad employment numbers
you will only benefit from the "social networking" coverage that it will bring you.
IT's a good thing. . . . . .
