I am doing some work on my son's Anni which is fitted with an Abbot big brake kit. I am having trouble sealing the lines at the calipers. The issue is getting a seal across the banjo bolt to the caliper. There is a washer either side of the bolt. Should they be copper or Bellville? The current ones seem to be copper but perhaps need annealing. Anyone know the part nos?

Inspect the sealing surfaces on the caliper and banjo bolt for defects and clean / anneal the copper washers

As Carrera says, check the mating surfaces. Then fit new washers if you've been re-using the old ones. There won't be a Saab part number since it's an aftermarket system but if you can say whether the bolt is M10 or M12 we can supply new copper washers. They should be copper washers. A belleville washer is a spring, not a seal.

If it's the Abbott 16" kit with 9-5 calipers then I'm guessing you need M10.

I'd go with new copper washers, but deffo inspect the sealing surfaces.

Just seen this. I had the same trouble with mine not sealing properly and have spoken to a chap that restores motorbikes who has encountered it too, the blame appears to lie with the non annealed copper washers, the mating faces where fine. Im pretty sure I even machine ground the banjo to make sure. The chap with the motorbikes used a soft aluminium washer that he'd sourced somewhere but i think i'd try to anneal the copper ones.

Because it's a slow morning I have just googled anneal. Hmm, I thought I knew what the process was but it seems I was thinking the exact opposite. In my head* I had it being heated and then dunked in some water. I must google and check stuff more often.

I respect that pun.

Also don't type too quickly when googling anneal.

"Showing results for an....." Quick Alt + F4!

I use't to use copper head gaskets on two strokes. Put them on the gas hob till they get a nice glow and let them cool on their own.
