I have a small leak in left rear caliper after replacement last year. I have tried to replace copper washing #9 in picture below, several times with no luck. An idea struck me, could the fitting #10 in the pictures possible have been mounted in a wrong way, making a leak? Can you answer me if it is identical upside-down, or if this could be the culprit I'm looking for. I'm tired of messing around with break fluid and appreciate Your input here.

 

Just to be clear, you replaced the #9 brass crush washer on both sides of the fitting, yes?

 

The fitting is symmetrical (top & bottom), but only really fits one way without twisting.

There has to be a sealing washer both between the banjo block on the line and the caliper, and under the bolt head that holds the block on.

Seems that a number of the replacement lines have banjo blocks that interfere with the machined place (or more accurately, the places that AREN'T machined, around the places that are) on the caliper. The calipers differ sometimes as well. The corners of the block keep the block from seating. In those cases, putting 2 washers under the block, will usually fix it. Used ones in good condition work fine.

 

This was last Autumn, almost sure I only did the easy one, as I can't remember I tore off the fitting. Sorry I'm not sure.



Thanks for clarifying. Your answer enlighten it all and I better start over again, with a few copper washers on hand.

 

Update. I now have two copper washers both under and over the banjo fitting. Still a small leak. My Next move will be to turn the banjo fitting upside Down. Maybe With different/New washers.

 

Replace the banjo fitting it is likely warped

 

Thread update, problem partially solved. Car hasn't been used that much and this problem was forgotten until it didn't pass inspection. I dug into it again and the fluid leak is not by the banjo bolt, but from the actuator lever. I'll Close this thread and start over again.
