9 bolt driver side brake line question
On the small distribution block that the hard line goes into with the sctew that goes with it. Does both sides if it get a brass washer? I can't seem to get it to stop leaking.

Super tight is not at all what you want. Spec is usually 17-22 ft-lbs. I would replace crush washers with new and try again. Make sure nothing is preventing the banjo fitting from sitting nicely on the caliper.

Re: 9 bolt driver side brake line question
Digging up an old thread.......I have the same problem with my 82 Trans Am.
I swapped the stock 10 bolt for a 9 bolt disc brake iron caliper 3.27 posi rear.
I cannot get the drivers side line to stop leaking at the caliper. I replaced both washers. One between the distribution block and caliper and the other between distribution block and the banjo bolt. I torqued it down, and it still leaks between the caliper and the distribution block. Does anyone know of a part number for an adapter that will thread directly into the caliper? That way I can eliminate the banjo bolt and distribution block. I'll make a new line and just plumb directly into the caliper.
It's the drivers side line pictured in this thread.....

Any help is appreciated.

Re: 9 bolt driver side brake line question
Make sure the surfaces are clean and not damaged. The factory commonly uses only a copper washer on the bolt head side. The brass blocks have circular machine marks for sealing but they won't seal up well if undone. An easy way to clean a caliper is to use one of those steel wire bristles/rotary brush, stick in in the hole and let it rip. IT'll clean up nice most of the time.

Re: 9 bolt driver side brake line question
Ok, thanks for the reply. I'll try cleaning it up and ditching the washer between the caliper and distribution block. This is frustrating.........

Use a washer a new one or if copper torch the old one first
