Re: plumbing in brake lines

3/16 is fine, easy-flex is the easiest to work with. Available at NAPA and O'rielly

Re: plumbing in brake lines

Today we replaced the rear brake line on a 1998 2500 dodge 4x4 cummins turbo diesel 200,000 miles,From front to rear axle it was 3/16 steel 11 ft long. Two weeks ago we replaced the rear brake line on a 1997 k1500 4wd ext cab Chevy it was 8 feet of 1/4 inch, it T'd off at the rear axle to the wheel cly,it was 3/16". I have used steel line from parts store for 30 years with out any problem SS will last forever but mild steel will GitRDONE! what ever you use make sure its double flared line DO NOT use compression fittings.

Re: plumbing in brake lines

I used the line from NAPA too. I looked at stainless but was told it was hard to get good double flares using standard flaring tools. I figure the factory steel lasted 50 years and this set will out live me.

Re: plumbing in brake lines

I just did mine last weekend. I installed a 99 camaro master cylinder with the existing 1/4" lines and still had very weak rear drums, changed to the 3/16 to up the pressure and they work great.

Re: plumbing in brake lines

I'll give another nod to the NAPA easy flex lines. I just replaced all of the lines on my truck with them and they are easy to work with.
