New Caliper/Flex Hose Issue.
I just changed an original (2002) Ford Right Rear caliper because it was hanging up occasionally and didn't want to take chances. So, I bought new Ford Calipers for left and right rear. The right was giving me the most issues, you know that burning brake pad smell. My flex hoses were new about, 6 months. I changed crush washers (copper ones from O'Reilly's) but I get an annoying small drip. It's very slow to form and slower to drop off from the connection point. My question is what size crush washer to use? The pack at O'reillys is an assortment pack and I thought I matched it up good. The banjo bolt is fine and I don't suspect it needed changing. Would you change out a banjo bolt with a new caliper install? What is the torque for the banjo bolt? What is the torque for the Caliper Bracket Bolts? I have seen numbers all over the place so I just want to be sure from members of the FTE. What is a good source for all Torque specs? Is there a manual out there worth buying that has it all?

Here is the pix of the Right Rear Caliper. The blue arrow shows that small drop of brake fluid. Crush washers are on both sides of the banjo bolt. Do I need to change to a different size washer? I compared previous versus new washer and could swear I choose correctly.

First, how thick were the washers? Cheap lines can come with .030" and you want .060"
The thin ones have ALWAYS leaked for me.
SUR&R sells a nice assortment of quality, thick copper washers.
I'm not saying this is your problem, only that it's the first thing I'd look at.
I've never known a torque spec for banjo bolts. For me it's always been so-it-doesn't-leak.

Well I can't tell for sure, but are you sure you have that flex hose on the correct side? I did that this past summer, I couldn't stop it from leaking went through 2 sets of washers, then I realized I had the darn block flipped over. Flipped it around and not more leaks. Felt kind of stupid, but I had two other look at it and they didn't see it either....LOL

I'll take a pix of my left side tomorrow and it will show the same position that the right one is seated. I thought of that too, but on a closer look there is a metal mold that would impede the brake hose from seating properly. I will start at replacing the new crush washers with a thicker pair.
