Unforgiven
solid fixture here in the forum
I am having a hard time with bleeding this system.
I am working with a 2004 chevy 2500 HD with a 6.0 engine.
This is a truck that I have completly removed all of the original suspension, and replaced it with a custom straight axle 4 link set-up.
The brake lines were disconnected from the calipers and at the rear junction block in the rear.
Truck has sat with no lines connected for about a year, so all the fluids have drained. This was foreseen.
last week I reconnected the lines to the new calipers up front and capped the rear at the old divider block
that was mounted on the old axle, that split and went to each drum.
The new rear axle has been debraked and is awaiting a new disk set-up in the future, This is the reason
I have capped them off.
THIS IS A STRICKLY OFFROAD MUD TRUCK AND WILL NEVER SEE PAVEMENT AGAIN
New to me is this style off master brake cylinder which has the power steering line plumbed into it.
I am trying to bleed the system and get the front brakes working. I have filled the master and tried to gravity bleed into the calipers with no success. I have tried adding fluid in a jar, then attaching a clear tube to the bleeder and pump the brake pedal. This has at least pushed some of the air out of the line and caliper, but
I still can't get a solid stream of fluid out of them. The pedal will in no way even try to harden up, it goes straight to the floor, and has resistance coming back up.
I refilled the reservoir and actually tried to blow into it to create some small pressure, then release the pressure.
This actually let bubbles purge out of the bottom of the cylinder. I repeated this until all bubbles were gone.
I then removed a plug from the rear line and tried to gravity bleed, A small amount of air was bubbling out the end for a bit but then it stopped. I let it gravity feed for about 1/2 hour but nothing was flowing.
I tried to pump the pedal and still nothing.
I was wondering if the ABS box is giving me problems with the bleeding proccess?
I can remove it all together, but I would really not want to deal with the removal proccess unless absolutly
neccesary.
Another thought I have had is to start the engine...maybe the power steering has something to do with assisting the brake pressure? I am not sure...as I have never dealt with this type of booster.
Are there any suggestions out there as to what I may be doing wrong?
