Does it make a considerable amount of improvement when the flex brake lines are replaced ? Does stainless steel wrapped make a difference ? What can I expect ?

 

When I replaced my lines with braided stainless steel, and this was including the two lines going from the ABS modulator to the frame, I did not notice an appreciable difference in pedal feel, which I was hoping for at the time. However, it was still a peace of mind modification.

 

To be clear, There are brake LINEs which are the hard pipes dispersing the brake fluid. Then there are brake HOSES which connect the hard lines to the caliper.
If you’re asking about replacing the flex hoses with stainless steel braided hoses then you might notice a slightly harder pedal, but minimal. Not to say the stainless hoses aren’t worth it, more for abrasion resistance than pedal feel. But every little thing helps. 😉
