Brake Pads....

[bostonmeche]

Hello,
I just bought a 914 about a month ago. Fortunately or not it has had a lot of upgrades done to it. 911 suspension, five bolt upgrade in the rear, bored motor, etc. The issue is that the previous owner did not do the work and there for knows little about the parts that were used. I now need new brake pads. After looking through previous posts and the tech section in Pelican Parts, I still have no idea which year of 911 suspension I have. Does anyone know how you tell which year of suspension was used? and more importantly, are all the break pads for 911 caliphers the same size?

Thanks in advance.

Sorry I can't answer your question, but I just wanted to welcome you to 914 ownership. There are a few of these up in this area, hope to see you at some PCA events.

There are the lots of different calipers for the 911. I would take the pads out and go to a Porsche Dealer to match them up to the correct new type.

The main thing about them is the brakes. Check two things: If a magnet sticks to the calipers (very likely) and the bolt spacing of the caliper mounting bolts.

Non-magnetic calipers will be the aluminum "S" calipers. They'll have a 3.5" center-to-center spacing between the mounting bolts. These brakes were optional from about 1969 through 1975, and became the standard brakes from about 76 through 79.

If you have 3" center-to-center spacing between the mounting bolts, the calipers will be magnetic and will be "M" calipers. These were the standard 911 brakes up until about 1976.

Brakes with 3.5" bolt spacing which are magnetic are the "A" calipers. These were standard from about 79 or 80 until 88 or 89.

If you take the pads out of the calipers and make a photocopy of their shape with rough measurements you can fax that to Porterfield and they will kindly tell you what you need. There is also probably a part number somewhere on the caliper if you want to go that route...

Thanks all! I think I have the info I need. Now I just have to implement it! I gotta get the new pads on soon before the good weather goes away again!
