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...
Jeff
To answer your questions:
Yes, the 20mm rotor will be fine and is what everyone sells for that application.
M-Calipers:
* 48mm Pistons
* Steel
* Ribe M8 Fasteners (13mm nuts)
* AP31 pad size (same as the early 914 front and 914-6 rear)
* Side Fluid inlet
* 3" mounting ear spacing
* 7lbs 6oz without pads
S-Caliper:
* 48mm Pistons
* Aluminum
* Early units are cast off the 908 caliper casting and are clear anodized.
* Later units are a combination of the 910 style nose and 908 rear and are greenish in color due to the dichromate sealant.
* AP45T pad size (same as the A-Caliper but the "T" stands for thicker)
* Side Fluid inlet
* 3.5" mounting ear spacing
* 5lbs 6oz without pads
A-Caliper:
* 48mm Pistons
* Steel
* Ribe M9 Fasteners (14mm nuts but small R6 heads)
* AP45 pad size (same as the S-Caliper but not as thick)
* Fluid inlet on the bottom of the widows peak in the back
* 3.5" mounting ear spacing
* Heaviest caliper ever made for a Porsche at 9lbs 4oz without pads. Read: PIG in the unsprung weight category.
Hope that helps. You're English is great!
Thanks a lot for your welcome, I do appréciate
And thanks so much to Eric for all the informations and the pictures. That's a great help !
I had a look at my calipers, and as the nuts are 13 mm Hex., they seem to be M version. I will check the distance between ears on tomorow,
Jeff
Your making fun of me...
your'snot would have been closer.
We don't make fun of you Eric .... you're quite capable of that yourself. In fact, I have always thought of you as about 2 cards short of a full dick.
