New caliper leaks at screw from brake hose. Sign In

Just got a remanufactured brake caliper on my 01 dodge ram 1500 4x4 and when I hook it up to the brake line it leaks when I pump the breaks. Leaks right underneath that square nut thing that has the screw go through it which holds the break line to the caliper. Is there suppose to be some kind of special seal there because there wasn't one there when I took it off.

It has to have a copper washer on both sides of "that square nut thing "..
It had to have one when you took it off or else it wouldve been leaking...It either fell off or its stuck on the square nut part of the hose or stuck to the old caliper.
They are NOT reuseable...get new ones....Make sure you put one on each side of the square nut thing...also make sure you removed the old ones.

The reman caliper shouldve came with them....They Usually come with all the necessary hardware including the copper washers ,but not the banjo bolt.(Screw as you call it)

And the two bolts that go through the caliper to the caliper bracket, get flat and locking washers?

I've personally never seen lock washers on the caliper pins on any vehicle I've ever done a brake job to but I think I remember seeing somewhere that some vehicles such as Toyota use lock washers. I could be wrong though. I've never seen them on any GM vehicle. If yours didn't have them when you took them off I wouldn't be putting any back on. Try and find a diagram on the brake system on Dodge's part website and see what it shows. I'm sure the mechanics here can give you a definite answer though.

These should be standard fare out there. Solid copper and the seal is the grooves which will impregnate/squish the copper some both seal and lock it. That's why they say never re-use them. Never saw one intentionally to be also a lock washer but some method may be out there for that.

Back a few posts - they should have come with them! Pic may not show but just like this if it does...........
