Hi guys, just joined as I've just got a 914. Need a little help with parts compatibility and wondered if anyone could help?

Car is a 74 914 with a 3.2 Carrera engine, 901 trans, and it stops with 911 SC vented rotors and calipers all round. Thing is, it doesn't have an emergency brake. The car was built in California but here in the uk it cannot be road legal without one.

Do I go 911 style drum in disc or 914 style ebrake on a calipers?

Thanks in advance

I'd say get some 914 rear brakes from Eric Shea that have spacers for vented rotors. That way you can use stock 914 parking brake cables and not have to engineer the pull mechanism that you'd have to invent with 911 rear drums.

For all of the money and time you would spend fitting a 911 handbrake solution you could go with a proper factory solution and bolt up factory handbrake cables for less money and less hassles. I know because I do both. I've built probably 12 complete suspensions using 911 components.

This is, in fact, why we went forward developing the VB914-6 and VB914-6/GT calipers. It's now cheaper to do it right:

If you're a stickler for originality, I have 3 pair of stock 914-6 calipers available @ $1,200.00 per pair:
(IMG:http://www.914world.com/bbs2/uploads_offsite/www.pmbperformance.citymax.com-1110-1376586924.1.jpg)

We also have the VB914-6 alloy calipers as mentioned above @ $799.00 per pair:
(IMG:http://www.914world.com/bbs2/uploads_offsite/www.pmbperformance.citymax.com-1110-1376586924.2.JPG)

The 914-6/GT versions would bolt up to your rear vented rotors for $899.00 per pair:
(IMG:http://www.914world.com/bbs2/uploads_offsite/www.pmbperformance.citymax.com-1110-1376586927.3.JPG)

All of these have the same 38mm piston size and the same FSMI D31 pad size your 911 rear calipers have.

I like this route best. You get a lot more braking power than 914-4 calipers and no alterations required (IMG:style_emoticons/default/smile.gif)
You won't beat that deal doing the 911 e-brake conversion unless you find a pair of 911 trailing arms with all the components, including the shoes, in usable condition for cheap $$.

Chris,

On your cable adapter, do you remove one half of the "butterfly" actuator on the brake shoe's?

Andys

Yes, that is correct.
It wouldn't work if the "floating" style cable installation was used.

http://www.rockauto.com/ has several options.

914-6 rears are $100 each, for example:

Hi Eric,
I have the 911 SC brake parts in hand and can handle the parking brake conversion. Would you comment on the differences between those vented brakes and the reproduction 914-6 brakes? I know what I have because I also have a 911SC, but I don't have familiarity with the original 914-6 because I am making it from a 914-4 as a starting point.
Thanks, and also thanks for doing all this stuff for us. Do you get to pour the metal?

To all those using brake parts sourced from Rockauto, O'Reillys, your FLAPS, and other non-P-car specialist sources: Please don't drive on streets where I, or anyone I know or like, may be driving. I don't care if you choose to use crap for your brakes, but I DO care that you might hit me when they inevitably fail..............

FWIW, the conversion wasn't legal in California, either. Nor in any state in the USA.

I'm just not hearing about brake failures anywhere in the news.
People hitting the gas instead of the brakes, yes.

SC parts will be even more difficult to fit. The bearing is larger and the hole diameter won't line up with a 914 control arm.

I think you're asking for a comparison of the SC rear caliper you have an the 914-6 and or our reproduction so, here goes.

Same piston size 38mm
Same pad size FSMI D31
Nose section is cast from the same casting, just machine out the hole for the adjuster
914-6 variants have adjustable pistons/pad clearance
914-6 variants have integrated handbrake
Our reproductions are under 3lbs each saving a total of 8lbs.
Fastener size on the 911 and 914-6 caliper is M7. Our reproduction is M8
Stock is cast steel
Ours is cast aluminum

I can barely pour my own beer let alone molten metal (IMG:style_emoticons/default/blink.gif)

Mid 90's vw passat looks like it may work on vented rotors with possibly an adapter to make the caliper mount correctly.

It has a cable actuated e-brake
