Bought this truck from a friend. Has been sitting for over a year. Blew 1 brake line, fixed it and two weeks later the driverside rear line has blown. Having trouble finding the area of the leak. Any advice and/or where I can find a brake line diagram? Can't afford a mechanic right now. Thanks.

What it might be is there is a divider block just behind driver front tire that feeds back brake line this might be what your looking for. Its kind of hard to see its hidden by inner fender liner and in a good spot for fittings to rust. I replaced back lines on both of my gen 2's. By the way if you have to replace the bacl line that runs down the frame. I can't remember what size it is but for long bed or short bed extended cab it will take 12 ft of hard line.

to bleed the brakes, you start with the right rear, move to the left rear, then right front, then finally left front. I hook a piece of 3/16 clear fuel line to the bleader valves and run it a clear bottle of brake fluid so I can see the air evacuating in the system. Have some one pump the brakes 3 to 4 times and hold, then loosen the bleeder valve and watch for air. once all the air stops coming out of the line, tighten the valve back up, and repeat until no more air bubbles are seen.

Break line

photo.JPG

would someone be able to tell what this is called? What does it do? And if i need to change it. The break line that runs from the block behind the front left tire connects to this which is on the frame near the rear left tire. PS. THE PICTURE WAS TAKEN UP SIDE DOWN. OOPS!!

Thank you.

That is what is called the load sensing proportioning valve... What it does is when you load the bed with stuff, it will add weight and thus lowering the frame down closer to the rear axle. This lets more brake line pressure reach the rear to help stabilize the breaking. It looks pretty rusty but I don't see any leaking... I would buy some WD40 rust remover and hit the rusted stuff to stop the rusting. The spray some lube on the moving parts and it should be ok... Hope this helps you :smileup:

It's no problem... you should be able to take it off, just make sure to hit all of the fittings with good penatraiting oil and let it set for a few minutes before trying to take them off :smileup:
