Front disc brakes leaking like a sieve

[Soylent]

First disclaimer is that I have never rebuilt brakes. Recently received truck back from mechanic. Working to get the hydroboost system running. Front drums were replaced with GM discs. Had a few leaky hard-lines so I replaced them all front and back. Bench bled the master hooked everything up and ran an errand. Came back and pools of fluid under front brakes. Took off banjo bolt and tightened the braided lines on the brass fitting then snugged down the banjo bolts. Still leaks like a sieve.

Took the banjo bolts out again because I didn’t remember if there were any washers. There weren’t any. Maybe they are not needed if one component is steel and one brass?

There should be copper washers on either side of the banjo.
Under the bolt, and between the banjo and caliper

Appreciate the help. Will pick those up tomorrow.

X2 you need a copper crush washer put on the banjo bolt, before you install it in the caliper.

So to make sure, one on each side of that brass block as 67 pointed out?

Yes - 1 on top, 1 below the hose fitting. The idea is that the copper washers seal the banjo bolt head to the fitting and seal the fitting to the caliper.

You’ll need 4 total to do both sides (2 each side).

that brass block

Are you sure it's brass? Looks like yellow zinc steel.

Yeah I think you are right. Like a yellow translucent finish.

Your mechanic installed the brakes and returned it to you that way leaking?

 

[Soylent]

Yes and no. Truck wasn’t finished and I got tired of waiting so I took it back. Banjos were initially loose so maybe a note to himself to finish the job? Still not drivable yet but close.

Copper washers fixed it. Thanks guys.
