Spondon caliper rebuilds/ tools?
« on: March 06, 2020, 06:12:13 pm »
I know this isn't the exact right section for this but where can I find seals and the tool to remove the plug on these Spondon calipers?

Is the left one leaking brake fluid so bad ? Or just spilled when unmounting ?

Worst link ever below.. And don't know the dimensions of the spondon...but you might need this or similair ?

( not to hard to fab either I agree with an old socket en 4 pieces of bar stock and a welder it should be a few minutes )

I thought that was how the pistons came out since it's monobloc?

Any source for seals?

plenty of room to get the pistons out , get the inner out first as it is shallower then the outer . if you try to take the plug out it will damage the threads .the plug  was only needed for manufacture .
as i have told you before these are a very poor calliper . people think they must be strong as they are one piece but in reality they are very weak in the centre and flex a lot . if you want to use them just buy lockheed seals they are what spondon used .

Didn't realize they weren't needed to replace seals so thanks for that. Makes life much easier. These will be on a street bike based on your previous recommendation to use Lockheed calipers for racing. Also nice that they take the same seals.
