I'm hoping some one here can help me out.  I bought a set of used extended brake lines for my Jeep Scrambler, the neighbor guy walked by and said I needed copper washers on the surface of the block that bolts into the brake.  My question is, do you need a copper washer on both sides of the block, or if not, what side is it needed?  Would check with my neighbor, but left for work.

Thank you for your help.

Yes, you need them on both sides; one on the bolt side, one on the brake line/caliper side.  This will allow you to properly seal the connection and prevent loss of brake fluid, contaminates entering the system, or air.

Yes, both sides

And new ones are better than used ones.

The copper being soft acts as a seal.

Yes you need them. I can tell you everything you need to know about jeep......I can even tell you how to flip a cj5 three times end over end and two times side over side and....um....never mind.

You need the washers.

The copper washers only go on the front  brake lines, right?

Go ahead, ask me about why you use new copper washers on every mating service......

Not sure on your jeep. If rear disk brakes....need copper. Drum brakes generally the fitting screws straight into the wheel cylinder=no copper.

Why do you use "new" copper washers on every mating surface, sitdwnabdhngon?


<––- using compression fittings on rear.

Glad you asked...

Once, I fell into the one copper washer trap, had a locked up caliper on the way home, had work in the morning and slapped it. The drive to work the next morning was terrifying with the brake fluid loss.

Same truck, some time later, yet again a cheap caliper failed and I changed it the night before work, reused the copper washers I had, using two this time at least. One failed, same story, brake fluid everywhere the next day.

As a teenager it was lessons learned the hard way. Now I buy good calipers and use new copper washers.

You need copper washers whenever you have a banjo, IME.

Pennies with holes drilled in them also work.    Did that when i was about 17, worked perfectly.  I would not try that now that i am older.

They go everywhere a rubber hose with a block attaches to a caliper or junction block.  If your rear brakes are drums, you'll probably have a hard line that attaches to a wheel cylinder and a rubber line and block where the hard line from the axle attaches to the hard line on the body.



edit: pics would help clarify if you have any more questions.
