Brake Lines for 1991 V3500
« on: May 25, 2015, 08:44:32 PM »
I am in the process of putting a lift on my 1991 Chevy V3500. While installing new brake lines to accommodate the lift, I damaged some of the factory brake lines. The original brake lines are pretty rusty and brittle. At this point, I am considering replacing all of the factory brake lines. Is there a company that makes good quality pre-bent brake lines for these trucks? Or am I better off buying the tools necessary and fabricating my own?

There are a few companies that offer pre bent steel lines.

I have tried searching for a brake tubing kit for the V3500's but have come up short. Will the kits for the pre-88/K30 trucks work on the later V3500's?

As far as I know yes they should, not sure tho. A K30 and a V3500 are the same thing, GM just changed the model coding (C/K or R/V) in the late 80s.

You couldn't get RWAL on a 1-ton.

Its not RWAL its a load sensing valve that applied more pressure to the rear wheels the heavier the load in the bed , starting in 87 I think.

there was so many problems with the sensing valve that gm even said to toss it if there was any problems with the rear brakes
