Full Version: Volvo Calipers in a 911 stut w/3" bolt spacing
What if I have the Porsche 911 strut with the 3 inch bolt spacing (for M calipers) but want to be use it with the Volvo calipers intead of the M? Will the calipers fit over the vented Porsche rotors? What model car has the ones that will fit. The parts counter guys always want make, model, year, etc for the calipers to let me use the 911 rotors (290mm x 20mm)
There are two Volvo calipers, one for solid rotors and one for vented rotors. Do an internet search on Volvo caliper conversions and on the Datsun (or similar board) there are lots of info.
thanks John, I allredy search and find all the mods. and a lot of info. but can't find the answer, some were someone said their are the same calipers for vented or solid rotors jus change the pads ?????? and have a set of new fronts rotors so i don't want to go wrong w/the calipers.
Do I need vented or solid volvo calipers???

ACEI's catalog listed them with the rebuiler's number followed by "V" for vented and NV for non-vented (solid). I doubt they are the same. The vent in the top of the caliper would indicate which they were for...vent = where the rotor rides and it's width.

I have one of each
from mista slits 
its true! they bolt on and only need a washer to center them on the rotor....
but they need a way bigger rotor to utilize the whole pad.....
i was inquiring about offsetting the mounting holes to make them sit lower on to the rotor

You're an effin engineer in training.....figure it out...If the caliper hat doesn't hit the rotor who gives a flip....grind away....and if you grind to much of the vent for clearance 'cause you want them real low, maybe the caliper will split in half. Work it out slide-rule boy!

hey! Can you post a side by side pics. also the measures of the thickness of the rotors spacing and the thickness of the pads.
look at sklines shalom with the vented volvo's..... it only uses the top 2/3 of the rotor..... and about a 1/4" of pad overhang
so... bigger rotor, or sit the caliper further down onto the rotor.....
Bernie said these are from a 700 series Volvo, all of them should be vented, you'll also have to do some mickey mouse engineering to overcome the dual circuit of the Volvo calipers...some have used lines to create a "T", I've posted diagrams to making an adapter.....

Tell us about your engine.
they are 240 series..... iirc
You want the calipers from a 240 series Volvo. Try an 81' 240 GLT I know they have the vented rotors. The calipers in Mikes pic are the 240's.

OK, learn me something.
What is the advantage of the Volvo claiper over the M caliper?

I feel much better.
Now then, how much do them Vulva calipers weigh?
Just wanted to see if I could make ya hurl 
JP, they weigh more than an M but way less than an unloaded A caliper.....
Saw them in the boxes at Joes, but didn't get the story of why they dont fit the rotor. Can the volvo rotor be used to overcome the problem ?

no way jose....
needs a custom rotor..... or caliper modification
aye... you guys made me go take pics of a vented and non vented calipers.....
RON - if youre listening, i need a 3100V caliper to trade for the non vented one

Aaron, Do you have the pair for vented rotors? Do you sell them?
How much??

go to your local FLAPS (friendly local autoparts store) and say youd like a pair of vented volvo 240 calipers......
90 each no core ...
Aaron...I went to my FLAPS and ran into a bit of a problem. There is no 240. There is a series 240 but they want to know which version of the 240 series to look at. Their computers don't list a 240 and they won't think past what they read. So which of the 240 series cars did you buy? (year included) 
i know 86 240's were vented....
but i wont run these until i sort out the following....
A ) machining the mounting ears to sit farther in on the rotor
B ) bigger rotor if A) cant be done
C ) pad options.....

'86 240 ok then.
Are the pads to big (tall) for the rotors. ie will they hang over the top?

YES. its because the CALIPER doesnt sit far enough down on the rotor, thus not utilizing the bottom 1/3 of the rotor, and leaving .25" of pad overhang.....
so these sit on my shelf till then
OK re read your post. What is the rotor diameter of the 240? Will the pads follow the rotor properly even if you bring the caliper down?

i lost the dimensions many a year ago
im sure a simple google search would suffice, let me know what ya find out.also, SOME 15" wheels wont clear, and you have to sand/grind the outside edge of the caliper (very very minimal)
just food for thought
I will be running 15 FUCHS over 911 vented. I'll keep my eye out for when you do it. I have a month or so till I have to start re-assembling the car.
these have been on my shelf for a year now......youll be waiting, unless you pioneer it first
they are lighter than A calipers tho

I might just pioneer. The bigger piston size in the M caliper is worth a bit more brake but the pads are the same. My car is getting preped for the Targa NewFoundland so add a passenger, a cage, baggage, and electronics. I will be heavy all the time. The extra pad would be extra piece of mind.

cool. figure out the caliper mod and we got a winner

Porsche 911 SC
282.5 x 20.5
smaller thicker rotor with longer caliper ears. Might be 1 too many problems then they are worth.
so an SC rotor solves the problem? cant be that simple...
its the caliper ears that make it stick out to far... i think the aftermarket rotor used was 11.25 .....

I don't know what you were using but the measurement sounds ok. Mine were like 11 3/16.
But I don't know if that solves the problem. The thickness is good (22 vs 20) but the volvo is the smaller diameter. So the hangover is in the ears, but what do you have for Volvo pad measurement? Have you put the 914 pad against the Volvo? How do they compare top to bottom?

I dont know what all the fuss is about. The volvo pad hangs over so grind the lining off so that it does not. You will still have much more brake surface than any two pot caliper. I have had mine for over two years and they work great. much better than stock. and they are very cheap at the pick a part.

Bernie,
Would you mind giving as much detail as possible regarding the Volvo front caliper swap... such as what rotors did you use and how did you deal with the two line ports on the Volvo unit.
Thank.
Tony
