Do I have 68 L brakes?

[teachKenpo]

I came across a set of front struts with 3.0 inch holes for the brake calipers. So I am assuming they are for a SWB car. The front brakes themselves have ventilated disks. The calipers are not aluminum. These parts were found with a 68 L motor. Would a 68 L have had S brakes? Would those brakes be made of steel? I want to put these on one of my 66 911 cars. Any help would be appreciated as my research has not yielded anything conclusive.

Yes a 68L would have had the same brakes as a 67S, a 68S was not offered for the US market it was an emissions reg thing. The L used a 'normal' 130HP engine in lieu of S 160 HP all else same as S car.

Those are standard M-Calipers. Came on the 67-68 911S and then moved to the rest of the line in 69 through 77. They would bolt on to your 66 car but, with that hub, the nose may rub on the wheels if you use the vended rotors. It's basically the same thing that's on a 66 (little different in the casting) but with spacers and longer fasteners.

Hope that helps.

Thank you Mark and Eric for the responses.
Eric, can you clarify your concern about rubbing? Presumably they did not rub on 68 cars. What would I have to do to make them work on the 66? Since the car in question does not have any suspension on it, I can put the complete 68 suspension if necessary. Also, this car is a R clone with wider front fenders, so fender rub is not a concern.
Thank you for you thoughts,
Regards,
John

I believe the only difference on '68 vs earlier SWB is a 7mm spacer on the back and a 7mm wider hub on the front, to account for 5.5" wheels.

The S brakes on SWB are the same and not aluminum like later cars. I believe only the 67S, the 68S and 68L, and all sporto cars had the S brakes from the factory.

My '68 is a "base" 911 but was originally a sporto so it has the SWB S brakes, vented all around.

Hi John,

Eric ("Neunelfer" here on this Board) does superb work on these earliest 911S / 911L brakes; he restored a similar set for me. Here is the thread with photos, it might help: http://www.early911sregistry.org/for...dy+brakes+1968

I understand that the aluminum S caliper was introduced late in the 1968 model year. Does anyone have factual information on this. I assume it would mean that the same struts as used on the 1969 and later models were used.

[Neunelfer]

I can put the complete 68 suspension if necessary.

Do that and you'll not only be better off, you'll be fine with regard to the rubbing. I was thinking that if you bolted those and some vented rotors to the shallower 66 hub, the wheel would rub on the caliper.

Thanks Andy! Checks in the mail... LOL

Thank you all for steering me to the right information. What I have learned is that I have 3 sets of these wide-L front calipers, but no rear ones. While it is not imperative, I would certainly like to find a set for the rear. Are they available? Anyone have a set? After reading everything here, I will probably have Eric restore a set for my current project, and I will save the other sets for my other 66 cars.
Thanks all for the fantastic help.
Regards,
John
