Brakes hoses

Scan threads where the brake fluid has been changed and the person states the pedal improved. Not saying that hoses won't make a change, but with the average person apples less then 200 psi in the hydraulics when they stop, and that's not enough to make a hose difference. During high decelerations it will and we can gain a hundred psi or so. That may or may not matter depending on the friction material on the truck, exceeding the tire skid threshold. Scott would live on this line at the track.
With every piston roll back there is an opportunity for micro amount of air to pass, especially as rust propagates under the seal. So 40k, 60k, .... some amount of distance, things get a little spongy, a slightly more amount of travel. Since we don't flush brake fluid like we used to do, the improvement does matter.
Lightflier, I'm sure you did but with longer hoses you just have to make sure during full compression to full extension the hose movement won't get caught by the tire or other wheelwell object.

I had the Russell lines for trucks with 4" lift on my stock leaf sprung truck. They rubbed near 3/4 full steering swing to full. I ended up replacing them with regular hoses. Coil sprung may not have the same issues.

Just received my brake lines from Crown. Will probably get it done this weekend.
Replaced the old lines on my 99 with Crown lines last year and it made a big difference.
I had my brake fluid flushed by the dealer and there was no change in pedal stiffness.

before I changed all my brake lines, I went through the ordeal of whack-a-mole eventually replacing all the Calipers. At each juncture I flushed the lines. It was hard for me to believe my concern was ultimately hose related. Who would have thought hoses "go bad"?

I will also keep checking for any rubbing or issues with the hoses.

Lightflier,
I wouldn't read too much into it. This is a brake thread, and there is soooooo much subjectivity in any brake thread that I don't take them seriously anymore. Sometimes I get back into them, can add the most rock solid data into it and the next post comes out of the twilight zone. Pedal feel is highly subjective first, and sometimes there is air that is elimated, and sometimes not. My intent was not towards pulling on you, I was just trying to affirm Scott's statement since he included my name. Often I post in forums speaking towards the group and not towards a post.
I just wanted to warn about long hoses getting caught, but from prior reads of your posts I though you would have done that already. Again, group speak.

Thanks for the explanation. No problem. Just wanted to be clear that I wasn't claiming any improvement specifically tied to the new brake lines. A brake fluid change could probably be beneficial to many all by itself. I only used the ones I did due to finding them on CL for $20 in new condition. Otherwise it would have been OEM. My old ones had 350k miles on them.

I need to buckle down and get hoses. It's the only thing I haven't replaced yet. Damn truck still pulls left.
