Ran across these calipers in a box of stuff in the shop.

Here is what I know:
Manufacturer is ATE
3.5" bolt spacing
4 pistons
2 inlets for brake fluid
3 bleeder valves.


Any ideas?

Wow.
How many do you have?

Contact Eric Shea at PMB, he'll know!

Then report back so we know too!

That's a Volvo caliper, IIRC. Dual circuit.

Yep, Crusty got it right, that's the earlier solid rotor Volvo caliper. I have the vented version on my car that was installed on the later model 240 series cars manufactures by Girling. They're big heavy calipers.. but have huge pad area..

Mystery solved.

Thank you!

Any use on a 914?

With 3.5 inch bolt spacing they need 911 struts to match. Those look like that are for solid rotors. Not sure how easy it is to adapt them.

All the Volvo stuff Ive seen are 3" but, as John states, dual circuit usually means Volvo.

Better to find BMW 5 series stuff. "very" universal 4-pot stuff used on BMWs, Ferraris and Lambroghini's. The Ferrari and Lambroghini's had massive spacers in them. Common kits etc. and you avoid the dual circuit plumbing intricacies.
