What brake callipers are these??

[paulm3]

Hi guys, anyone know what type of caliper / disc this is? It's on my westfield seiw 1997.

Austin Princess looks a likely candidate.

They look like 'princess' 4pots - this was a hot conversion way back when B4 the custom 4 pots became available for sensible money.

These are Princess 4 Pots.

HiSpec supplied callipers for the Westfields as standard...so it could be one of theirs.

There is something about them that doesn't look like an OE calliper

[rdodger]

They look like AP to me.

Are those anti vibration gizmo's fitted correctly?

Should they be like this?

I'd say hispec as they look identical to the ones I'm about to stick on ebay only mine are a nice silver.

All the HiSpec stuff is machined out of Billet, these look caste. The AP picture looks correct AP7600 with the shim the wrong way up.

Look like early Metro calipers. Similar were fitted on a few BL cars... and it's a long time since I saw any so don't hold me to that.

The anti-vibration plates are almost correctly fitted... and it's not really an issue. They should be rotated 180' as the raised ridge to the outside should be inside for the wear warning wires to pass under.

They aren't Metro calipers because they had two flexible hose connection points on the back of the caliper for the two independent brake circuits. They have to be joined together with a bit of hard brake line to be used on conventional systems (e.g. mini's).

Are they iron or aluminium? The internal fluid transfer, uneven split line and the anti-rattle clip with the pad warning cable relief suggest it's more like to be an OEM caliper rather than an aftermarket performance item from e.g. AP, Hispec etc.

Disc looks like standard Ford Cortina parts (apart from being grooved and drilled).

They definitely don't look right to me either.

They are definitely not! There are numerous significant differences.

The Princess calipers had two separate flexi hose connections for the split circuits, like the Metro calipers, and the threaded holes come out at a ~30 degree angle from a large cast in boss on the back of the caliper. The OP's picture shows a single flex hose coming out at 90 degrees and there is no hard line to couple the unused output to one of the bleed nipples which would be required with the Princess calipers.

The Princess calipers have the bleed nipples mounted on the top of the caliper, rather than the side of the cylinders as per the OP's picture.

The split line on the Princess caliper is equal, i.e. both halves of the caliper are the same width. Clearly not the case with the OP's calipers.

The only thing wrong with the anti-rattle clip as shown is that the top end is not quite located correctly within the center of the caliper, and if we are being pedantic they are mounted upside down since the pad warning wire exit is on the wrong side, but that is irrelevant in this case. Apart from that it's fine, there is no other way it could be installed.

Sierra cosworth perhaps?

Why not give Westfirld a call with the chassis number/email pictures and see if they either have a record of what they sold or if they can identify.
