Re: Bought C3500 basket case
Thank you guys for the input. I am mostly happy and need to attack the power brakes, get some new spring bolts, and figure out the old electricals. Then it should be mostly roadworthy.
What does it mean if the brake pedal goes down and feels solid and stops the truck, but then the pedal doesn't come back up? There is a small spring I can see under the dash, seems fine. Is this a booster issue? |

Re: Bought C3500 basket case
Most likely explanation is you have a leak somewhere in the brake system. Replacing the master cylinder is a good idea in general, but especially if you don't have a lot of confidence in the previous owner's care of the truck.
You could also just bleed the lines and see if the problem goes away, first.

Re: Bought C3500 basket case
I guess living in California your idea of rust is different than here in NY . I've seen much worse and fixed much worse . Like been said make sure the fram is safe and if it were mine I would go threw the entire brake system . I may be on the extreme but I change all the wheel cylinders on drums and all rubber lines.

Re: Bought C3500 basket case
Just occurred to me that if they messed with the frame, then they messed with the brake lines, I would start there.

Apparently the front rubber brake lines for these trucks are no available. Ten years of threads with people trying to find them and not a lot of for sure answers. |

Re: Bought C3500 basket case
Is the SPID label still on the glove box lid? Just wonder if it started as a 133" or 157" wheel base. If it started as a 133" I would not see a need to both cut the frame and move spring hangers....Im betting they moved the spring hangers and bobbed the rear of frame. Its to bad they didnt hold out for a Longhorn bed.
I just bought a 70 C/30 that still has the factory flatbed. It seems they usually get changed out to something else after a few different owners.
