Back brake pistons (at wits end)

Zip/cable ties are really strong especially in the more chunkier sizes.

Where can you get stainless pad retaining pins?

A g-clamp is re-usable and helps push stubborn pistons back in

Agreed but if you've done the job properly they should just push in by hand.

I got mine off ebay a while ago now. I had a check earlier and cant find who sold them although i spose if you've got some tools you could even make some yourself from some 5mm stainlees steel rod the awkward bit will be drilling the hole for the r clip to go through

Indeed, is it really necessary to upset the end like on the standard one?

If so then could turn down a stainless bolt to shape. Which will be a bugger, but oh well.

If you don't push them in 100% true, they can jam ... Mr G-Clamp sorts that

Anyway, yes hold it back with anything, but I like using a g-clamp

I'm conducting a survey. Which bleeding method did you use mate?

Mityvac. Just took it in turns front and back bleed nipple.

The Mity is quite good- but can be a little hard to tell if the pipes not on the nipple too well as it pulls air in around that as well as from the brake system.

I suppose a bit of ptfe tape might help that (Gah! Now I think of that), but the ensuing froth can make it hard to check the condition of the fluid. Though this is more of a problem on the back bleed nipple once the brakes bolted on again, as it's more awkward to get to.

Still- having had to bleed the system 3 times to get both pistons out and re install the caliper, I can confirm that it does help the whole operation.

2 people and a 1 way valve bleed system (just a little pipe with a ball bearing in it) is also pretty good- this is how DirtyDog did the front calipers last weekend. In fact, 2 people doing it really makes a difference.
