Banjo washer not sealing
Permalink  
 

I got everything installed on my fiances truck, rotors, bearings, pads, calipers. Got everything bled, pushed down the pedal and she asked if there was supposed to be something dripping from the truck. banghead 

I tried turning those copper washers over every which way, tightening it, making sure everything is as clean as clean can get, and I cannot get it to stop leaking. It appears to be leaking at the caliper to brake line connection. The calipers I got were remans from NAPA and the only thing I can notice is the grooves on the bottom of the opening on the caliper are really non existent. Do you guys think this is enough to keep it from sealing tight? I'm open to anything because I am out of ideas. 

Both sides of the line and caliper shown below.

Pictures are not working. But I would make sure the banjo bolt is not somehow bottoming out before it is tight enough to compress the washers.

That's definitely a real possibility and of course I screwed in the bolt to the old calipers and already returned them for the core charge. I'll take a look at that tonight.

Are you sure the square head of that hose is fitting in the round area of the caliper.  I might also be thinking the line goes on the caliper differently then what it does. But it might be worth going back to the store and have them pull out your old calipers to compare them.

New washers sometimes need to be messaged in. Tightening and loosening back and fourth a few times will often times get them to seal.

I went into NAPA and explained what was happening. They gave me a little bit shorter bolt, and a hair thicker washers to make sure the bolt wasn't bottom out. Got home and it was still leaking. They warrantied me a new caliper, got it on last night, and no more leaks! Must have had bad threads or they weren't machined perpendicular to the surface? Nonetheless, bled the brakes and went out to seat them and during that I noticed that under heaving braking it pulls very hard to the passenger side. Also, I should note, there is a ABS light on, was on when we got it (I'm hoping it's a speed sensor, but it's OBD1 and I have some research to do to figure out how to use that), but I don't know if somehow that could be causing the module to send more pressure to one wheel over the other?

Um, most brakes want light to normal braking for 300-500 miles to seat, not heavy right away...maybe the brand you bought are different ?
As a curiosity, which side is the warranty caliper on ? If the side that pulls, maybe the other one is a reject too and not engaging properly ??

Huh, I've always read to seat the brakes that you bring them up to temp slowly, casually braking, then 8-10 stops from 60 down to 15ish repeatedly braking hard and then back to speed right away, then driving without braking to cool them back down again?
The warranty calliper is the side that it is braking hard on......I suppose it's a possibility that the other one could be bad too and not engaging as hard?

I would suspect the other caliper isn't working properly.
