New brake install

I need to shove the drums on.

I need to shove the drums on.

What? You've been bleeding you brakes with the drums off?

 

[kiwigtx]

are the rear shoes adjusted ?

Yes...that is very important...otherwise pedal travel is taken up moving shoes, and not creating and fluid/pedal pressure.

I just did a complete system bleed on my truck, and it took a while to get the fluid moving...but when it started it was easy. Using a Wilwood proportioning valve also.

need a power bleeder
well it helps speed up the bleeding procedure anyway

one man job easy peasy

no fuss no mess

yeah IF I understand what you just said,
you need to put the drums back on
without the drums on, to have the shoes press against
it will never make any pressure
well hardly any, anyway in the rear wheel cylinders, have no resistance
you'd have little to no peddle resistance either

And you can pop the pistons out of the cylinders !

yep, it could...

C’mon mans! The drums are on when bleeding, I did check to see if the wheel cylinders are working by having my buddy slowly press the pedal with the drums off (one side at a time).

I even pulled the calipers off, stick a piece of wood between the pads and had my daughter push the pedal. Took a few times but finally got the piston to move.

Still not getting anything good from the rears.

Lol, had us going.

They either go together and work or they get to be a pita! I'm wondering how you can check that MC for pressure?

Anyway to use another one laying around?

If the rear shoes are adjusted, and the drums are on....then try this...

Master cylinder lid is OFF when doing this ....
1. Remove front caliper nipples - do one side at a time....
2. Gently press brake pedal a couple of times (pressing pedal fast will likely shoot fluid out in a geyser like jet),
3. Allow some time for gravity to allow fluid to the caliper,
4. Gently cover & remove a finger from the caliper bleed nipple hole...crating a mini vacuum (like fingering a flute),

After a few minutes you should see fluid come out of the bleed nipple hole

It works, and we did that to my truck also.

After the fluid starts to slowly run out of the nipple hole, replace nipple bleeder, and tighten.

Repeat on other side.

Then you can start pressure bleeding.

Most important....wash up spilt brake fluid with water....NOT Brake Cleaner.

Hows the brake hose on rear differential going to block? Check that brake line front to back.

Distribution blocks can fail shut.

Distribution blocks can fail shut.

Not the one on rear diff
I forget how the front one worked with brake warning light. My old one was frozen but still let fluid pass to rear end

I’m done for today. Sometimes it’s best to walk away and leave the BFH in the drawer.

The lines are all new except the 2 front hard lines.

I’ve never had this much trouble getting brakes to work, but I haven’t ruled out the factory distribution block.

I should have made myself more clear....on the way to the rear lines on the diff. Agreed that the rear diff block should be fine - it is just an open distribution block/junction.

 

[5.7 hemi]

That block was blown out using compressed air when I put in the new rubber flex line and stainless hard lines on the housing going to new wheel cylinders.

 

[steve from staten island]

The distribution block under the master, is that clear, is it old, did you flush that.

 

[5.7 hemi]

I was able to get the bottom fitting off and clear fluid came out slowly then I had my son press the pedal and more fluid came out, still clear.

 

[khryslerkid]

Maybe this might be your problem though I never did except on abs systems. Just a thought...

 

[5.7 hemi]

I’m calling Dr. Diff aka Cass, and see if he has one. I’m thinking that the drum/drum valve is my problem.
