87 dually 1 ton brakes

[nickdenault]

So I’m kinda new to this but I have a 87 gmc r3500 and I have all of the metal brake lines and the rear hose, what I can’t find to purchase are the 2 front brake hoses, all the ones I can find are for either the 1/2 ton or 3/4 ton does anyone know if there’s a 1 ton version somewhere or if the 3/4 ton will work?

I bought new from rockauto last year for a 4x4 dually. Shouldn’t be hard to find for a 2wd.

That ‘87 R and V series stuff confuses a lot of folks and sometimes the parts catalogs. You might consider looking for parts for an ‘85, they’d be the same.

The 3/4-ton front hoses usually work on the 1-ton trucks too since the front setup is basically the same. A lot of people run those without issues.

The hoses may interchange if the banjo bolts are coincidentally the same but 1 ton brakes very different, 1/2 and 3/4 tons are the same.

I replaced my front hoses on my ‘77 K30 dually with hoses from Off Road Design.

we had this recent thread with some links:

if the metal ends are good, I kind of like the idea of Napa or some other shop that has rubber line by the foot rebuilding existing.
