Re: ongoing brake fluid leak
I used to heat the copper til it rainbows and then torque the bolts to spec. Boom. Make sure there is no paint on the caliper as well.

Re: ongoing brake fluid leak
I've had that issue a few times. Pop's told me to tighten it 1/8 turn until it stops leaking. Always work.

Re: ongoing brake fluid leak
I am having the same issue on a 1970 Pontiac. The bolts are also VERY tight, much more than the spec. I also had a nightmare getting the hoses to stop leaking on my 72 Cutlass. Are they making the copper washers more cheaply and less effective? I am 64 years old and have been doing brakes since I was 18 and NEVER had problems before. I just put on the washers, installed the bolt, torqued it down and drove away.
When you heat them, do you install while still hot? |

Re: ongoing brake fluid leak
Double up on the copper washers.
I had a disc conversion leak like that once and more washers helped. |

Re: ongoing brake fluid leak
This is happening quite often, it's usually the copper washers, probably not annealed properly. China strikes again. I usually change to a different pair and the replacements usually seal.
