Working on a 1987 4runner, I’ve been focused on freshening up the brake system under the hood. My brake lines seem to be in ok condition, so I was thinking I could just replace the nuts on all the lines to freshen it up. I live in north west California, where it’s coastal and rains a lot, so rust is a big problem for me. I’m wondering if I have the correct size for everything. Lines: 3/16 Flare: double inverted. Tube Nut: M10x1.0. I was planning on buying a pack of stainless steel ones from “4Lifetime”.

Also, anybody ever bought products from them?




I’m also swapping out the old master cylinder for the v6 one. I put it on as is and it rusted like no other, took some time the other day to wire wheel it and paint it
