Copper Crush Washers on Front Rubber Brake Hoses
#22
Melting Slicks
A couple weeks ago I bought new front brake hoses for my Jeep. I wish NAPA didn't include those darn washers with their hoses. I installed the new ones (one on each side of the block) and put brake fluid in the system. When I went under the Jeep both sides were leaking (more like pouring) brake fluid. So I'm in a hurry to tighten them and with the adrenalin I snapped the banjo bolt that holds the brake hose to the caliper. When I examined everything carefully, I discovered that the washers they provided were half the thickness of the originals (.030 vs .060). The caliper had a recess in it that was deeper than .030 so there was no seal at all on the caliper side. Once I went to the Jeep dealer and got the correct washers and a new banjo bolt, they sealed with no problem.
The point of this post is that you need to make sure the dimensions of the washers are exactly the same or they may not work properly.

MYK7, I think you are right. I didn't realize that there are 2 different pictures. The second picture shows it broken in half. The second picture has things restored i.e. painted parts that should be natural, new cushons.

You fellows are correct re that clip. THANKS! I don't believe they can be bought separately so I may have to pick up an entire u-joint kit just to get a clip. I am checking with Corvette colleagues firstly. Most of us have basement inventories.

I did not get ambitious today in the absence of the "correct" copper crush washers to put the new hoses on. (Actually the old hoses look almost brand new??). But the Wife did help me with the bleeding of the system, old style: pump and bleed, pump and bleed, then hold. She did keep pumping and holding the gas pedal for awhile (she does not drive) and I could not figure out what was going on. But that little oversight was sorted out . Yes Lars, my accelerator pump works: the engine was flooded but did burn off cleanly.
My original concern was the brake pedal going almost to the floor. Obviously not a good situation. Now I have a good 1 1/2" to 2" clearance and a nice firm pedal. Yes..........!
People often speak of DOT3 needing to be flushed every couple of years. The fluid I drained out was a murky/muddy mess. The humidex here today was 109*F but I am glad I got the job done. What more can I say about preventative maintenance. That I should observe.
These small little successes for mechanical neophytes like me are important. The Corona is cold and...why not have one?

My research indicates that they are very specific dimensions for the Corvette calipers. If you are near a Corvette supplier let me know. I need four. I will pay you of course but hopefully will avoid a $10.00 administration fee and $15.00 shipping plus UPS brokerage fees for $5.00 worth of parts. Just pop them in a postal envelope. I can send you a money order.

Look better? All kidding aside I wish to thank the keen observers who brought this to my attention. Yes, that new clip is in the groove.
Before.

Not sure how I missed this post until today.
I didn't know they were Corvette specific , I don't think I have ever purchased these all my extras come with new hoses. I have 2 different sizes .450x.685x.061 and .446x.625x.062
Your choice , I'll just tape 4 of them to the inside of an envelope and drop them at the post office.
They were free to me so they are free to you.
( I'll email you for your address.)

Not the first choice but in a pinch:
Not the first choice, but in a pinch, you can take a propane torch and heat the washers up to cherry red and let them air cool.
What this does is anneal the copper and gets rid of the work hardening from the first use.
I would check the surface for nicks too.
I used to do this with copper gaskets on oil plugs with success.
But, getting new ones is without a doubt the first choice. After all, this is for the brake system which you really need to stop the beast

I'm getting a little mellow tonight. You fellows who noticed that bad circlip may have saved me much misery such as a busted battery box. Thank you sincerely!!

Paul. What are you using instead of French locks on halfshafts? Also I noticed cupped washers on lower shock mounts are turned wrong way. Cup should be to tall nut. Not nit picking just observing. mike...
