    Ok so I bet some of you may remember the whole stump pulling incedent...

    Well replacing this line is easy and actually the question I have doesn't involve this specific section of line but rather the main rear hard line before the axel on the frame. i notced this after i took my bed off yesterday and wasn't sure. I think the PO might have used compression fittings to replace a section of brake line, but I'm not sure. Here's a picture:

    I just want to make sure that these aren't comprssion fittings because I know that they are a big no no for brake lines...

    Hey Glenn,

    I'm kinda funny when it comes to brakes. It's an area I will not take any short cuts in. Had that been my truck, I would have been on the phone to LMC Truck and ordered up the pre-bent replacement line immediately. That jerry-rig is not safe in my eyes and I'd replace the whole line, and give my rig a good bleeding. Again, that's just me and how I operate.

    Manny I totally agree! That little section must have been like that for god knows how long and should be replaced. I already have a replacement for the pinched brake line and as soon as my buddy returns my vacuum bleader I will replace it.

    Well, I knew already that you had a replacement for the pinched line. I was talking about replacing the hard line where that splice is in place. By the way you wrote your response, it wasn't clear if you were leaving it, or you had a replacement for it already. Like I said before, I'd replace the hole line from the proportioning valve all the way to the back.

    Its leaking from three different places in that splice, should be enough reason to replace it compression fitting or not

    Not its actually not leaking. What you see there is water after power washing the frame and then blowing it off with my compressor.

    Either way it should be replaced...

    Or it could be water from pressure washing your frame and giving it a thorough inspection :doah: :D

    Hi Glenn,

    I think that the point he's trying to get across is whether they are compression fittings (which he feels they are) or not, that set-up is dangerous for you to have. It was never meant to be that way, and is a weak spot in the braking system. Any malfunction there can lead to total brake failure. I agree with Dafey. You've pulled it all apart. Replace the line to be 100% SAFE! Just lookin' out for ya dude!

    If you used a block , like the rear brake lines use on the axle , and capped the unused port and flared both lines to go into the block , would that be a better fix until a new one arrived ?

    I'm not sure what you are trying to say. There is no unused port on the block splitter thingy for the rear brakes.

    I'm a little confused with LMC. It seems they don't carry prebent brake lines for K series trucks. They only list the C series. I don't think that the rear brake lines would be any different but check out the page:

    I meant , could someone use a rear brake block m which has 3 holes ( one for each side and one for the flex hose ) with the third hole plugged , as an emergency fix if you have a flare tool handy ?
