Oh for sure, what an abomination!

Seriously though... if I had a leak at a banjo bolt that could be completely and safely rectified by simply adding an additional crush washer that I had on hand, I sure as heck wouldn't bother driving several miles just to buy a thicker crush washer. That's SO OCPD IMHO.

If you think 3 is bad you would die at how many were on the 88 formula. I was doing the brakes and putting new hoses on and I wish I was kidding but there was 7 normal crush washers on the passenger Side caliper. I used 2 thick ones that are sized for a cpi fuel system shrader.
only reason i even suggested trying 3 is because if that seals up at all then 2 thick ones will be completely fine

My roommate is very insistent that we simply over tightened the banjo bolt and now the soft brass of it is squished. I don't buy it but I'll humor him. He could use a good humbling anyway. Regardless I need to get more washers, so to the hardware store it is!

To me, I prefer 'properly' on my Fiero and I do not care if you want to call correctly as "OCPD"

So yeah - you guys can put as many crush washers you want on your Fiero caliper and call it "completely and safely rectified".

Follow the mob if you want Doggo and you have the gist of the matter....Good Luck!

And I "do not care" if you think adding one additional copper crush washer is SO Mickey Mouse.

Sounds like you need to run a bottoming tap through the threads, or the banjo bolt has a defect.

Other idea: assuming it is the piston which was defective on your original caliper, maybe you can use the replacement piston in your original caliper housing (which presumably has a good threaded hole).

Next, put two crush washers on the brake hose fitting and Measure the assembly {i.e. the Out Diameter}

The first 'Measure' MUST be smaller than the second 'Measure'



This is good advice, and is applicable to bolted joints in general.

If there are too many crush washers, then the thread engagement of the banjo bolt in the caliper will be inadequate, and this could be considered unsafe. However, we don't have much information (measurements), so it is difficult to conclude on this topic.

Totally agree. I was only suggesting the use of one additional copper crush washer for a total of three... not seven.

I will get precise measurements when I get home with new banjo bolt + washers Promise!
