No brake fluid to the rear drums. *shakes fist*
 
1 Attachment(s)
I just replaced the MC, but I'm not getting any fluid to the rear brakes.

The shop taking care of it while I'm out of town (or I'd have done it myself) wants to replace he rear brake hoses, so does anyone have a part numbers you can share for the rear hoses to the wheel cylinders, so I don't buy the wrong ones 15 times.? 😁

Mine is a 67 with coils and 8 lugs

I'm wondering if the lines may not be kinking when it's on the ground, but in the mean time, I'd like to get the hoses right and stray ruling things out.


Pic of the truck for attention!

Thanks!

There are no hoses to the rear wheel cylinders . The only hose is from the frame to the rear differential from there it’s all hardline . I believe 67-8 use the same hose . Hose I used on my 68 with coil springs the hose for the leaf are different

It's a center line that feeds a T, isn't it?

Makes sense. (this would be easier if I were under the truck instead of relying on someone else)

Yes . On the 67-68 c10s with coil springs the rubber line goes to the passenger side frame rail . I just replaced mine. Not sure about 3/4 ton trucks

Shop should know this, but there's always a question of whether the differential pressure valve has shifted to the back while bleeding and closed off the back system
.....assuming you have front disks

It's 4 wheel drum, but I asked them that same thing.

I've personally had that hose clogged on 2 trucks, you'll also find many threads on here where other have...

if it's good and old, cracking that rear hose loose without kinking the long line isn't trivial either
