BDisc Brake Banjo Bolt Washer source
 

I'm having trouble getting my banjo bolt joint to seal. Seems it's a common problem due to replacement copper washers are harder than the originals. I first tried to seal mine with the original washers - no luck. Then bought a set of replacements with the same results. I've torqued the bolt up to 35 ft. lbs. and am afraid to go much higher (spec. is 25 ft lbs.) Anyone have a particular source they've used for softer copper washers?

I read they can be heated with a propane torch and allowed to cool to make them softer. Haven't actually tried it myself though.

Hi Jim. I’ve got a few new ones. I’ll send them to you to try out.

Cheers, Anthony.

I'm having the same issue with replacement calipers on an '80 TA. I could feel the new washers where stiffer, but never thought about being too hard to indent and seal. Might have to try the annealing process.
Thanks for the tips...:biggthumpup:

Hi Jim

I've had two sets of the ones available from HBC and they have always worked fine for me. I just installed another set on this yellow car and plan to bleed the system out real soon. I don't expect any problems with them as they have always been good for me in the past.

i had the same problem ..... i had the rubber hose on the wrong side . have a really good look at the end that has the copper washers .

hbc ???

They also have new banjo bolts if needed. BRK-1083

Thanks for the link. I didn't know what hbc was. Too many acronyms now days for an old fart to keep up with...:tongue:

Thanks for the info guys. The set that is in there right now torqued to 35 ft. lbs. is a new set from HBC. I am also using a new set of banjo bolts, may need to take them out and compare them to the originals.
Barry...not sure what you mean by rubber hose on the wrong side. Can you help with more info?

What he may be talking about is the steel banjo fitting on the end of the hose. They have a slight angle to them and if the hose is installed on the wrong side, that angle will not let the banjo fitting bolt tighten to the caliper ... the fitting must be angled away from the caliper, not toward or against it. Hope this helps ...

Thank you, I'll check that as well.
