2000 GMT400 CREW CAB SFA SWAP-The Warden: Fuel leak fixed and awaiting surgery…

The ultimate goal for this truck is tow duty/family camping trips/small offroad adventures.
It's your truck telling you that you need to drive it more often.
You have no idea how many times I look at that truck and want to drive it instead of the Duramax. I need to get the rear window resealed and finish putting the interior back in. Then it will get driven more.
 
Time for a roll of 3/16" and 1/4" copper/nickel brake tubing..
Brake lines here pop on a nearly daily basis,my friend does a few hundred vehicles a year ,and usually will do every line at the same time,because once one pops,the rest usually are ready to fail also..

I hate rust...your frame looks twice as thick as my trucks,mine probably lost half its thickness now that its almost 40 years old..
 
It's hydro boost, and I have honestly never messed with one before. Can the hydro boost unit just go out like that?

To answer your question, no. The hydroboost cannot directly cause a loss of brake pressure. When hydroboost does go out, you just lose boost (which would produce the opposite problem, a pedal that's hard to press).

Good information to have! Thanks!
 
Moved this the other day to do more dirt/gravel work for the shop pad, and I had hardly any brake pedal. Went straight to the floor. No leaks present anywhere. Fluid level good. Steering felt fine. Any ideas what I should look for? It's hydro boost, and I have honestly never messed with one before. Can the hydro boost unit just go out like that?
It happens a lot to trucks that sit a long time.
My suburban did the same.
A new mc and she was good
 
I remember the days of growing up in the midwest and having to replace all steel brake and fuel lines on just about any beater truck you bought. Really glad I don't have to deal with that anymore.

I've noticed a massive increase in rust since we moved onto a gravel road. This is honestly the first time I've had to replace steel lines on any truck I've owned. Now I've done my fair share of wheel cylinders, but not a lot of lines.

Do they spray the gravel with anything to keep dust down or just leave it be?

Good lord is it dusty all the time! lol

No, they just leave it as it is. When I mow down by the tree line/road, it looks like I am spraying for mosquitos due to how much dust makes it up into my yard.
 
That sucks. Some of the county maintained gravel roads by me get watered. The road dept has a big old military water tank trailer on an old semi that I always see doing one by my house.

That would be nice. There has been talk for a few years that they were going to pave our road, so not sure if that's still on the table. I suppose a call to my Rural District wouldn't be a bad idea.
Drive it more.
This is the plan. I have always had 2-3 vehicles that I rotate for daily drivers, and having just one vehicle has been bothering me lol.

Ditto for me too,every car or truck I ever had needed at least a few metal brake lines replaced,if not all of them.
It's a suck job,not that "hard",but lying under a vehicle flaring the lines is not fun at all..

I bought a few 25 ft rolls of the green coated steel tubing from a vendor at the flea market,he was getting $14 for 3/16" and $18 for 1/4"...got one of each,plus I got a bunch of "leftover" pieces ranging from 3 to 6 feet from my friend when he cleaned up his shop,much of that is the galvanized stuff though,that usually rusts in a couple years in one spot enough to pop..but its free,so I'm going to use it up..

I wish I had held off and bought the nickel/copper tubing instead though,you'll only have to deal with replacing lines with that stuff once...but it would likely outlive my truck--or me,so the coated steel tubing will be good enough..

I did every brake line on my plow truck in 2011but I used the cheap "ready made" lines with the fittings already installed,and am surprised none have popped yet,some have rusted spots that look ready too..

The guy I get my inspection stickers from "tests" the lines by stomping HARD on the brake pedal 3-4 times with the engine running--if they didn't pop then back in July,I guess they'll be ok for a few months more..usually I have a line pop in the middle of winter while plowing--or a rubber hose cracks and blows...
I put new front hoses on around the same time as the lines,but they already look 20 years old,not less than 10..

I put a braided stainless steel rear flex hose on the truck,I found out one for a Chevelle or Nova is identical and a friend had a new one lying around and no use for it..he was going to chuck it out!..it fit perfect and it was a good thing I put it on right away,the old rubber hose had the crimp fittings almost completely rotted away !...:eek:
 
That brake fluid was just bored from not getting to do anything. I wanted out to play.

Drive it more.
The thing is that people either forget or don't know but brake fluid needs to be changed every couple of years because it will absorb moisture from the air.
Water. Is heavier than brake fluid so it goes down and settles on the low spots and rust the lines from the inside out.
 
I've never had to flush the brake fluid,mother nature & road salt lets it out long before it is contaminated..:doah:..

It's true lines can rust from the inside out,but here the outside almost always rusts away first...the box frames on later model GM trucks rot from both sides here too,I have seen some that still looked nice externally,but were paper thin and full of rust flakes inside..
One I saw like that started to fold in half when it was put on a lift and raised up to work on it..
