I think that $20 air bubble mentioned above ^^^ occurs at the split ,  since air bubbles  naturally  float up , hence -----  pinch off one side and work one side at a time  -----Hey Shade , if I pitch in for some gas money and a Popeye's 6 piece tender , will you ride over to Jeep's and get him straight , LOL 

6 piece ain't gonna cut it !.

The guy who supposedly wants to buy it is in Little Rock.  Maybe I should just tell him to get it like it is, have him drop it off at Shade's, and let Shade's OCD kick in.  He'll re-rebuild the whole thing again LOL

Maybe a 12 piece tender will get them brakes bleed.  Shoot a double dozen would still be a lot cheaper than taking $$$.00 off the selling price cause the brakes don’t work. And that wouldn’t look good on you having to send it to the specialist guy in Little Rock.  Might still cost you a 6 piece any ways Lol. ——— Isolate one side at a time.

Heading out in a minute. Will try doing one side at a time again with the other side clamped

 

Almost through a big bottle of brake fluid with what I’ve done so far.

Got sidetracked yesterday and most of today, but recruited Mrs Jeep to help out. 

 

I said “I knew I’d get you wrenching with me sooner or later!”

 

She said “I can sit on a 4wheeler drinking beer and squeezing a brake lever.”

 

Anyhow, get vice grips everywhere, bleed driver’s side, then passenger’s side. Still spongy.

 

Go back and clamp both sides. 

 

Figure out with drivers side clamped right above the top ball joint, have a firm lever. 

 

Now we’re getting somewhere. 

 

Unbolt caliper, tap on it, wiggle it around to try to work any air in there to the bleeder.  

 

Still spongy. 

 

So I go get another caliper out of the shop, swap them out, same thing. No air coming out of bleeder, brake lever is perfect if I clamp the line as low in the system as right above the upper ball joint, but the lever goes all the way to the handlebar and is spongy as ! if I take the vice grips off the line.

 

So I’ve isolated the issue to the last 3 inches of brake line and the caliper.

 

I’m all ears!

simple: air is trapped in the line.

Awesome job man!

 

It sounds to me that there is a leak in some component that is allowing air into/out of the system but not leaking fluid. 

It's that or a very stubborn air bubble. I would have said it was the caliper but you most likely ruled that out with the swap.

 

Easiest way to make sure the bubble goes out is to make that side the high point in the system. This would involve basically rolling the bike on its side if that is something you can do. Maybe try a sander with pad only for vibration. Check for leaks with the old soap and water method or bust out some UV dye if you have some left over from a radiator. (doesn't take much)

 

Man, you are almost there!

How big of a syringe are you talking?  Seems like it would have to hold enough to completely fill the system or you'd let air in when you pull it out to refill the syringe.

 

You are right. I think the one that I use was used for feeding calves formula. It has a rubber tip and holds maybe half a gallon.

Don't need it in this situation though. You have almost got it and that would basically start you over.

You might have to change that hose , could have a flap of rubber inside blocking the flow or trapping air , or rust build up inside the hose barb of the banjo fitting ..... also the hose could be flexing ( swelling )  under pressure ----  how do you like that isolation method ? -------  your 1/2 way there , could leave the one pair of pliers under there and send it with one good brake , LOL ----  down to a 12 pieces now

were the pistons pushed all the back in the calipers ? with the bleeders opened ... then ... installed and pumped up ? because a completely empty caliper .. can do the same thing your having issues with ... at least I've seen this happen ... before, because the standard is to push the pistons (bottom them) in the caliper housing when dry...... to push the air out.

I completely bottomed the caliper piston. 

 

That sander idea sounds interesting.

 

I think I might unbolt the line and stretch it up as much as I can, try to force the air up. 

 

I also wondered if the banjo fitting on the end of the line might have a partial blockage.

 

Will mess with it when I get time.  

 

On that note, I just  got a call that my oldest (16) daughter’s boyfriend’s father passed away earlier today. He had a lot of heart issues and apparently passed suddenly today. The boy was with my daughter at her mother’s when they got the call. The boy’s mother took off when he was a kid so his dad was raising him alone, and now this. Poor kid. Just started his senior year. 

 

Anyhow, might be a bit before I get back to this.

Even if your family member's issues are known... barely makes it any better. Poor guy is right... Wish him the best of luck in persevering through.

It's not the hand you are dealt but how you play it.

Progress, finally.

 

Took yesterday off work to attend the funeral.  The kid's dad was 57, had had 3 heart attacks, and 20+ stents over the years.  Just a bad deal all around.  The guy was the captain of the local Fire Dept so those ceremonies really make you tear up.  The kid was composed throughout, but in my experience, after the initial shock, getting the funeral planned and all the activity around keeps the loved ones so busy that they don't have time to really grieve.  That comes after the ceremony, when everyone is gone.   He's going to have a rough time ahead.  Y'all keep him in your prayers.

 

When I got home yesterday I made my daughter come out and talk to me while she was helping me bleed the brakes.  I unbolted the caliper and knocked it around (hoping to get any air in there moving where it would work its way to the bleeder), and then bungee corded it up to make sure it was higher than the T in the line, then bled it there.  With a C-clamp in place I got a firm handle.  Then I reinstalled the caliper and it went to mush again.  I took the caliper back off, and tried to remove the pads, and they were firmly stuck in place and wouldn't move, so what was happening was the piston was pushing on the pad, but the pad wasn't being pushed into the rotor.  On the outer pad, the caliper wasn't pushing in, so the caliper was moving back and forth but wasn't moving the pads at all.  I swapped another bracket and set of pads in place, and bam, nice firm lever. 

 

Need to put new shoes on the rear brakes now, clean it up and get it gone.

Got the rear brake fixed yesterday.  Apparently the rear brake pads were worn too much to use, even though they looked like they had lots of material left.

 

The new pads I had for the rear axle on the next project went on, and I had to have my kid spin the opposite wheel while I tapped the drum on with a hammer, but it was a good tight fit, and now I have a nice firm lever for the rear brake too.

 

Next is breaking the rear tires off the bead, cleaning the bead and rim, and slopping some grease on there to hopefully solve the rear tire slow leaks. 

 

Then I'll ride it a bit to make sure it's all good, wash it, hose it down with some SC1, and hopefully sell it.

in the future, slid a hub on the rear brake side, use a pry bar in the studs to turn the axle while your hammering the brake drum on over the shoes, this way it lets you work alone..lol.

Yeah, but I have kids around.  Might as well make them earn their keep, right?

 

At first I didn't have enough of the axle showing to even get the hub on there.

not following ya on not enough axle ?, unless your talking about the hub splines were gone ?, but you can also use a pipe wrench on the axle to spin it. but yeah..if ya got kids around...make them earn that allowance !..lol.
