Brake Calipers W&N or E24?

[scottau]

Hey guys
I need a set of calipers (one of the few items by non-runner was not supplied with) for a '72 CSA.
I'm considering W&N new as they are currently on sale, or I can get a set from an E24 and refurb those. Anyone have experience with these options??
Thanks
Scott

i think there are 2 versions of e24 - the e12 based (early cars) and the e28 based (later cars). if i'm not mistaken, the e28 based versions do not fit well.

I bought the W&N front calipers a few years ago when they were on sale. The installation was fine, but my EBC green pads with about 8mm thickness would not allow the metal anti-squeal plate to fit. The pads don't squeal w/o the plate. The pads were about 10mm thick when new and were in the OEM calipers with the plate.
Perhaps the W&N pads will fit the W&N calipers. I also have the W&N cross-drilled rotors for the 3.0CS.

We don’t buy Walloth because it’s the wrong zinc plating. Yellow is correct.
Go with early e24 calipers with yellow zinc.

1.Yellow zinc plating​

This particular zinc coating is most seen in the automobile industry and offers a middle level protection against rust and corrosion. This plating is ideal for use outdoors due to its substantial anti-corrosive properties.

2. Blue/clear zinc plating​

This type of zinc plating generally offers a lower level of corrosion protection, however it has the advantage of being more environmentally friendly than its counterparts. Blue or clear zinc plating is largely used for machine parts, washers, screws and for ornamental purposes due to its attractive finish.

What about CAD plating? Would that hold up better? Seems we have quite a few still doing this in Ontario.

Just to add re the plating.
Due to a EU directive there has been a move away from hexavalent to trivalent chromium in the passivation process. In the UK we noted this change on our parts at the beginning of this year, notably calipers. We are not able to get yellow anymore using hexavalent passivation (I am involved in the restoration of half a dozen plus cars, my own plus part of a friends portfolio/collection. All to a very high nut/bolt standard). I am told by the small number of platers/suppliers of plated products that we use that the trivalent corrosion protection is at least and typically higher than yellow hex . There are very limited highly regulated platers able to do yellow hex, but at great expense. The parts we receive are now Zinc and Clear and have a light iridescent blue colour. Aesthetically, generally the finish looks better, somehow more intense, robust looking. The old yellow hex zinc plating could tarnish quite quickly, this is holding up slightly better.
Re the W&N calipers, would be interesting to see whether hex or triv has been used, and if they have salt test data...or even tacit knowledge from their suppliers.
I'm building a fast road e10 taking much learning from my gr2 race cars.....every last nut, bolt, bracket etc has been plated yellow 12 months or so ago......any new stuff I get done/buy will now be silver! Same with the restos, they will unfortunately be a mix of yellow and silver. We have about 300 bags of sorted and labelled yellow nuts, bolts, washers, fixings etc on boards....as the weeks go on more silver creeps in.

I believe yellow zinc is correct.

The shop I use does yellow Zinc.

I think cadmium followed by yellow zinc is great.

Fortunate in the US you are still able get the yellow. Whilst out of the EU, in the UK we're still driven largely through adoption of regulation! Is the us likely to go down this same route re hex? California already regulated?

We have a set of newly plated calipers in yellow on one of the e28's here next to me, they look much better than the zinc/ clear silver ones
