1st Square HELP!!

[jastewart25]

Hi all,

So I recently purchased my first square body. I have no experience with these vehicles and the "GM Pull" issue.

It's a 1985 Chevy K10 350 with new brake hoses/pads/calipers from previous owner who did a pretty thorough restoration (lets say 1 year old). Pretty much new everything under the hood but I guess he was selling it for a reason.

I really want to take it out on the highway but just riding around the fields @ 40 mph a semi light tap on the brakes throws the vehicle HARD to the right. I mean, it's scary!!! Now, it doesn't do this all the time. It also throws harder to the right the faster I am going. At lower speeds just putting around the property it will every now and then lightly pull to right but I also have just been lightly tapping on brakes. It does not pull to right when not on the brakes.

A few fellas around that had these back in the 80's say "they all did that" I just can't imagine driving a vehicle safely that does this.

Any help is greatly appreciated.

Right now I am replacing BOTH fuel tanks as previous owner did not disclose they were leaking. Talk about dangerous. I'm dying to get on the road and in the woods but feel to unsafe as is. Ordered 16gal replacements from LMC.

Anyway, thanks and look forward to your help! If I need to post pics to help figure out the problem just tell me!
