Thanks again for keeping me on the straight and narrow bmorgil: I think I have forgot more than I know about fixing cars. But I do want good brakes! In the early eighties I was in the army and stationed in Germany. I bought a decent Mercedes 230 SL roadster. What I later discovered was that it did not pass the German inspection because of rust. Therefore, I hired out all the repairs and brought it back to the US. So that is when I discovered the need for good brakes on a CJ5 with over sized tires. While towing my Mercedes behind my CJ5 I had to do an emergency stop. I ended up in the meridian of a 4 lane highway and rolled/totaled both vehicles. I was lucky to walk away with only a scratch on my leg. The state troop said I was lucky that not many people walk away from roll overs. Ever since then brakes and brake maintenance has a pretty high priority to me. I will mostly likely call KW when I get to the point of rebuilding the brake system. I am pretty sure they should be able to provide some guidance since they sell the kits. I have one more related question. Is the DOT 3 brake fluid satisfactory or should I use the DOT 5? I understand the benefits of the DOT 5, I am just wonder the use the the old jeeps.
