Front brakes on 914/6, Request for infos Options

[jeff9146]

Hello everybody !

First of all, as I am a new menber, let me introduce myself,

After restoring a 911SC, I bought a 914/4 . After buying, I discover major rust on the body. By chance I know a very clever body worker, and the job is on the way.

Last summer, I had the opportunity to buy a 914/, second hand, in very good condition, so I bought it.

At the moment, I am having a look at the front brake system, and there is something I do not understad very well.

On my PET, the référence for the rotors is 477.405.083A (20mm thick, the same as for the SC)
And on the rotors I have on the car, the engraved reference is 901.351.041.16 , 18,5mm thick (my PET says they are for 911 T/E/S) with calipers ATE 245

My questions are :
- will the calipers be OK with the rotors 477.405.083A ?
- what are the differences between the M,S,A calipers?

Many thanks for your answers,

I apologize for my poor english, but you know, I am a frenchie... (IMG:style_emoticons/default/smile.gif)

Yes, the 20mm rotor will be fine and is what everyone sells for that application.
