AP Calipers - Which Model number is correct?????

[Richie]

Your calipers are for max 330mm diameter disc x 28mm width.


Just looked at my calipers for my 362/378 discs and they have part no CP5555-802S4 etched where yours say CP5570. They also have CP5555 where yours has.

The 5555 is the generic family number for the six pot.

Your calipers are for 330mm discs.

They are from the 5555 caliper family, but yours are 5570
You then have pad options from the 5570 family, probably D51's.

If your old set-up used this caliper on a 330 disc the radius at the back of the caliper will be to small for the 362 also mart.
But where there's a will there's a way.

Indeed Cosmo. I will have a go at making this work as I just cant justify near £900 for a pair of calipers similar to mine in every single way except for a radius.

Thanks to all that have posted up to help with this, great site this !

Thanks Kelv, can you recall the pad depth on those pads in the picture at all please? from the inside edge nearest the bell to the outside edge inside the caliper not the actual pad depth please?

Thank you

Unfortunatley not, I didn't ever measure them so I can't help on that one.
And they are now sold and on a FRS in Birmingham somewhere.
Hopefully someone has a set of pads on the shelf for the 5555 caliper who could be friendly with a tape measure.

Ok thank you Kelv. Yes that would be nice if possible, im searching the web and theres a bit of confusion as some sites say 80mm some say 50mm. 80mm seems way too deep to me.

Thanks again.

Check out the AP Racing website Mart.

There are pdf cad drawings of the calipers and pads fella.

And YES 80mm is wrong.

you still wanting bigger Mart.

if you did machine them you will need slightly bigger spacers to push the caliper away from the center of the hub.

mart pm mike rainbird as he have the pad sizes as he might have them on the dhelf

[Mike Rainbird]

You're going to have to sell them IMO.....

All the CP5570 callipers are, are a set of CP5555 machined down to a narrower width (the callipers are two halves). So if you made them accept 32mm discs by machining material off, you would forever have problems with pads, where you would have to machine a couple of mm off the thickness EVERY TIME you bought a new set for them to fit properly - not really ideal. You COULD send the callipers away to have a 4mm spacer put in, but that would probably end up costing more than selling them and replacing them with the correct callipers......
