AISIN Calliper rebuild - what the heck is this clip for?

Just rebuilt a pair of AISIN calipers for my SJ:

Other than the calliper bodies, which were stripped and painted, everything's new. Pistons, seals, rubber boots, retention rings, retention clips, pads, bleed nipples, even new bleed nipple caps.

The thing is, I have an extra clip for each calliper that I don't know what to do with:

What the heck is that last little clip for??? Is it something to do with holding the brake hose? Doesn't look like the brake hose clip I remember...

Hewp! Am I being a twerp, or what????

I got a pad retention clip kit - I was expecting 8 clips - 4 left handed (2 per calliper) and 4 right handed (again, 2 per calliper). You can see a single set in the 3rd pic (haven't installed them in the other calliper, because it turns out that DOT4 not only lubricates pistons making them easier to push in to a calliper cylinder, but also STRIPS PAINT LIKE A BOSS - Doh!).

Anyhow, I received 10 clips, not 8 - I got 2 of these weird extra clips!

I can't, for the life of me, think what they could be for...

Never seen them in a pad kit so doubt its for the pads.

Maybe for another make or model that shares the same parts.

There's half an hour of my life I won't get back searching for what those soddin' clips do.




And I still don't know :S

As we used to say - "Throw them at next doors dog" :thumbup:

Good point - although Barnyzuki on facebook is telling me that it fits between the calliper and the slider, and that there is two of them per calliper in a Suzuki kit.

I can't for the life of me see how you can fit them between the calliper and the slider - unless I'm thinking of the wrong part?

I thought the slider was the brass collar thing that the bolt goes through, to let the main calliper body move?

The kit is called a "Delphi LX0432" kit. I can't remember where I got mine, but they're available from Brakes International. The part number is BPF1671, they're charging £9.08 for 'em right now.

What I did buy from Brakes International is 2 pistons, BCP5114, £18.94 each, and 2 bleed nipples, BBN95, £1.25 each.

I bought a Jimny calliper seal/rebuild kit (5131) from Big Red: http://www.ebay.co.uk/itm/310606656144 - . Enough for both callipers, but no sliders included - I reused my old ones. £27.90.

Brakes int. do a rebuild kit, BCK5119 - costs as much as the Big Red kit, but only does one calliper - but it has new sliders.

I stripped down the callipers, then took a wire brush and cleaned them up before painting them, then rebuilding them (one still has to be reassembled, because it turns out that DOT4 strips paint LIKE A BOSS and now I have to wait for it to dry out so I can repaint it, then finish rebuilding it).

It's easy to do, just time consuming to clean 'em up and paint 'em. I put copper slip on the sliders to stop them seizing, but the seals on the Big Red seal kit for the sliders seems to be airtight - if I move the slider around, the seals "puff up" or "shrink back" as the air moves, so I think they'll repel dirt and water, so they shouldn't seize up. Still, copper slip can't hurt, can it?

Getting the pistons out was a PITA. I ended up making this:

Getting the piston out was the only difficult bit. You can use a compressor, or so I'm told - the cheap type you inflate tyres and footballs with, not a powerful one (which would probably shoot the piston out like a bullet and kill you). But my method was basically to wind a bolt down into the calliper, which gently pushed the piston out - I made that little contraption so I could use a smaller bolt than the hole on the calliper, so I wouldn't risk damaging the thread. In the end, it was so gentle, I don't think I needed to bother - still, better safe than sorry.

I only found this *after* I'd finished, but this is essentially what I did (but I also cleaned/painted mine):

As for cost - if you don't need new clips, pistons etc - just seals - then you're looking at £28 for the Big Red rebuild kit.

I think in total, I paid about £100 on parts, including delivery and the pads. Not bad, since I got everything except the sliders, bolts and calliper bodies new - and that's the cost for refurbishing *both* callipers. I now basically have 2 reconditioned callipers in as-new condition.

I can't see *anywhere* where it'll fit. It's driving me nuts!

How'd you think *I* feel??? I'm the one with a piece of a BRAKE CALLIPER left over! Nightmares of brake failure due to some stupid tiny smegging freaking clip not being in place...

I've got the rebuild kit with sliders. Just need some of the pad retaining clip.
