Break line leaking at banjo bolt, need suggestions
I have a 1997 GT and recently I started to hear grinding noises from my back breaks (skipped squealing and went straight to grinding). I assumed it was simply my break pads needing replaced but when I pulled the wheel off on the passenger side I noticed that the roter had only been gouged on the inside and not the outside so I checked the caliper and found that one of the pins had seized in the bracket.
Considering that my car has 180k miles and the rear breaks have probably not gone through much maintenance I decided it was time to replace all the parts so I installed new calipers, brackets, roters, pads for the rear breaks on both sides. Then as I was trying to bleed the breaks the break line on the driver side started squirting out fluid at the banjo bolt where the break line meets the caliper.
Initially, I thought that the caliper I bought may have been defective so I replaced it with a new one and still had the same problem. Then after some searching I found a guy with the same problem who claimed that it was simply the copper washers on the banjo bolt as the new washer replacements were half the thickness of the originals and didn't thread the bolt like the originals. So I tried using the original washers like he did and no luck, it was still squirting out of the banjo bolt when I started the car and applied pressure to the system.
My next guess is that somehow the seal created by the banjo bolt and the cube housing against the caliper isn't happening so I'm thinking about using a new washer and sanding the cube housing smooth but if anyone has better suggestions (apart from replacing the brake line) I'd be very grateful.
