This is try 92 to get a message to post - I am now trying our local boy
scout hotmail account - hope this one works.....
sorry list!
I have a 46 1/2 ton. I have rebuilt all of the wheel cylinders and the
master cylinder. The truck was on jacks stands and mostly level. Well I
was able to bleed the lines using a one man bleed kit. It has a magnet and
the draining bottle sticks to the wheel well above the cylinder. It seem to
worked - took out all of the black fluid and once it started running clear
with no air I turned off the bleeder valve and replaced the screw. Off to
the next wheel - all of them with the same result.
However, I can not sustain any pressure on the break pedal. I can pump it
up (8 - 10 times) and it will be firm for the bottom 1/3 of the press to the
floor. After 30 seconds this pressure is loss as well. I have placed the
wheels back on the truck and moved it to a very level spot. There is no
leakage of break fluid form anywhere I can detect. I will try to re-bleed
the wheel cylinders again.
Any suggestions?
Second issue. I have purchased new break shoes and placed them on the
truck. To start with I have turned the wheel cylinder/pad attachment screws
all the way in. The rear wheels still drag on one spot in each revolution.
I know I need to get the drums turned. If this will not take care of the
drag what should I do? I purchased the break shoes from Carter and they
assured me they were the correct size. I have matched them up with the old
shoes and the look to be the same to me. Any hints would be appreciated.
Thanks
