curious as to what the volvo 4 spot calipers are made from (alloy, steel etc.)
there appears to be a few different brands to choose from (girling, ATE and i think one other)
and how much do they weigh (just curious...not a deciding factor) compared to the rx7 s4/5/6 caliper, the r33 caliper and the hilux caliper

early volvo 4spots seem to be made of lead -or something equaly as heavy and dense. later models used alloy but they're all renownedfor being heavy suckers.
hilux caliper is also a heavy thing
the rx7 caliper (well the example cool1 showed me) is quite light in comparison.
there's some recent threads on RA/TA brake upgrades plus the ongoing MA61 brake upgrade threads that discuss weights of different calipers.
i take it that you're considering alternatives to the pug+hilux upgrade for your RA40?

I have a set of alloy Volvo calipers here which are about the same weight as the RX7 ones I have. The only thing is I don't know what they are off as yet so I haven't don't anything with them

yeah for ra40, the possibilities seem to keep on going for methods to upgrade them.
i have been trying to hunt down rx7 calipers for cool1's method which i like (i got close but there was a small...issue),
i think the r33 will be too hard to fit in my rim, and for some unknown reason i don't want to do the corona/hilux route.
so i was wondering where the volvo caliper fitted in on the equation of brake upgrades for the ra40, they have a caliper that suits a 26mm disc...which might match up to the s2000 rotor as per cool1's method, but i was curious as to what they were made of and wether they were any good or not.
cool1 can you take pictures of the calipers and i can go talk to a volvo wrecker and see if they know for you, i haven't looked into all the volvo models myself yet to find out what calipers go with which car, but am more than a little curious.

I can't tell you much on teh volvo brakes but I do know that they are used on a lot of MK1/2 escort race cars. Maybe look into an escort forum for info.

The early ones are heavy as buggery cast iron, and there are two sizes, the bigger of which takes a DB549 pad.
They are heavy but work well, although you have to be careful of the dual braking system porting.

The early Volvo caliper that takes a db549 pad was used from '76-'83, Girling & weighs 4.5 kilo. inc pads. Used on 240,242,244,245,246 & 265 models. The ATE caliper takes a db62 pad & weighs 4 kilo.less pads. Used on '75-'82 245dl &'83-'86 240 dl&gl. The third make of caliper used was Teves but I have no info on it. The dual line system does not present a problem. They are cast iron & extremely rigid. I have a pair of ATE ones if you are interested. Can't remember how much the Hilux ones weigh, but I remember when doing some adapting with them once thinking they made Volvo ones feel pretty light.

cast iron they are used alot in torana brake conversions because the stud pattern is the same. weigh about as much as a hilux caliper, and fit under a 14 inch rim ( not all 14inch rims as constuction varies) for a celica id use rx7 4 spot or an aftermarket 4 spot like wilwood, ap racing or brembo if your loaded

Cast iron  Some maybe, all no. The calipers I have are what are used on the Escort rally cars as said above and they are made from alloy!
I'll try and get photos in the end of april when i'm home again.

Cool 1
Do the alloy Volvo calipers have four pistons?. I think barned01 was specifically asking about four piston calipers. I believe later Volvo calipers were alloy,but didn't realise they were 4 piston.[never seen any] Do you have any info. about them please.

yeah i knew they were four spots (they renown themselves on bein one of the best cars at braking) but i didn't know what material they were made from, hence the question, all the calipers i mentioned are 4 spot i believe.
but now there seems to be an alloy version of the volvo caliper, could find out what models they came off and use that as an option as well for the brake upgrade...unless of coure those Escort thugs have bumped the price of the alloy volvo caaliper up...

There is a site called turbobricks, a bit like a volvo version of toymods, might be worth looking that up
