850 ATE calipers on 740
 
Hi all!

Does anyone know if this is doable? The 740 parts are getting harder to find and having a newer option would be nice.

I just want to know if the 850 ATE calipers will bolt onto a 740?

850 caliper (part # 19-1702/3/8/9):

It appears to me that the bolt holes are not the same distance apart.

Sure are a lot of calipers available on Rockauto.

The junkyards, Eeuro, FCP scrotum, IPD, all the usual suspects have them I don't see a problem.

Its just a picture. No reference on how far away it was taken. If anyone was actual dimensions that would be great

Thats all fine and dandy but having options is a good thing? right? :roll:

It's a 7/9, you're supposed to crush it once a bolt-on brake caliper is more than $14.99 shipped...

They made 9 series up to 1998 in europe and 1995 here, I don't see the issue...

P80 FWDs only existed another 2 years and they don't bolt on or do anything "better" than the original calipers and take the same pad even IIRC...

You seen one crappy sliding caliper you seen them all.

why not convert to a 940 'big' brake setup?

Up front the 850 calipers fit with longer bolts and a small spacer. Easy way to get bigger 305mm brakes

jvluntzel 05-17-2018 12:22 PM

I dont think anyone is understanding the point. Its simple. Do they bolt up or nah?

Do they share the same part number? If so, yes. If not, no.

Those are not sliding, 2 piston fixed caliper.

They should fit. I just gave my buddy my 940 caliper off the rear for him to install onto his S70 since both mounted just fine.

I have installed 850 front callipers and 305 mm rotors on my old 1986 740 turbo. You will need 850 brake calliper brackets, a spacer plate and longer bolts in the front.

850/x70I FWD rear calipers are a direct fit for a 740/940.

There is a quite detailed thread in this section, explaining the 850 caliper (same piston diameter as the 9 series) and the 302/305 rotor conversion for the 7/9. Not quite a 4 pot Wilwood upgrade with big rotors.... but an upgrade none the less. You do need a custom abutment bracket to make this work..... mine came from Skandix.DE

If the OP just wants to repair, certainly there are parts in the supply chain.
