Coupe of questions about brakes. First of all what is the difference between "M", "A", and "S" capliers? Is it the mounting bolt distance? Early vs.Late? (IMG:http://www.914world.com/bbs2/html/emoticons/confused24.gif)
Did the 914/6 come with "M" capliers? If not what did they come with? Can these brakes be upgraded to something like the "big reds? |

Ahhhhhhhhhhhh Hello, Clay...
S-Calipers arrived a tad before 74 Uncle Clay (IMG:http://www.914world.com/bbs2/html/emoticons/wink.gif) There's no such thing as a stainless sleeve for an S-Caliper. Stainless pistons are the trick. The corrosion in the bore "generally" isn't the problem it's the corrosion on the piston where it sits in the bore and rests against the seal (picture included) A-Calipers don't look anything like an S-Caliper (it's twu, it's twu). Same pad surface area but not as deep as an S-Pad. This is such a common myth. They look like they're from different manufacturers. They look more like the BMW Calipers people are using than they do an S-Caliper. M-Calipers were never (ever) used on 914's (post 73 or whatever), they were stock on 914-6's and 911T's though. And the bore is about 5mm larger than a 914-6 (me believes... I can confirm if desired) Other than that "You're SPOT ON Clay" (IMG:http://www.914world.com/bbs2/html/emoticons/smilie_pokal.gif) (IMG:http://www.914world.com/bbs2/html/emoticons/w00t.gif) John, what engine do you have? If it's a -4, I wouldn't go with anything larger than an M-Caliper. I have my reasons which I'll go into detail if you really want to know. Many, many BTDT experiences. Attached image(s) |
