Hi Guys,

I am trying to find the right numbers of the seal kits AND the pistons ( I damaged a few). I did get the seals for the bigger pistons in the caliper, but still need the smaller ones (38.1mm).

One big piston is damaged too much. Maybe I'll change them all. I think I found the seal kit number of the smaller pistons, but the numbers of the pistons still fail.....

I can't help you with a part number but RaceParts in Wallingford were really good when I was chasing various AP parts.

I have been using them for years for all sorts of stuff.

Great service.

OP, give them a call on +44 1491 822000 they will either know or find out the equivalent part number.

I found this info in the equivalent parts thread, it mentions a 4.5 Cerb and yours is a 4.2, both using the same calliper?

Well, i used demon tweeks. By my mistake i ordered only the big pistons in the caliper. And i did damage 1 or 2 pistons. So, I wanted to place the porder at demon tweeks and he asked me for the referende/serial number ion the caliper.

One 1 side of the caliper it says 5200 102W 26 N 5 DT. On the other side is says 5200 105W.

Nothing more that i can see what numbers are concerned. But apperently it is not enough information the determine the pistons (and seals).

It's obviously your perogative to use whoever you want to, but when there are specialist brake suppliers who work closely with AP directly why would you choose demon tweeks over one of those others ? Makes absolutely no sense to me. Demon tweeks is for stuff you need quickly and don't mind paying a premium for , for everything else there's no reason to use anyone other than people who specialise in this kind of thing ?

For me it was a hit through google. Live in the Netherlands. I did not know better.

The part numbers of this previous thread... are these the actual piston numbers?

It turns out BCS can’t get the AP pistons or seals any more so have sourced the complete set from mailordercarparts.co.uk. 12 pistons and 4 seal kits = £274 delivered.

Will still send the whole enchilada to BCS for the refurb.

(in my defence I did call BG developments but they have not yet replied and I want to get this done sooner rather than later)
