I am looking for an upgrade to my front stock calipers and the "M" caliper for solid rotors seems to be a good choice. The car has a 19mm master cylinder and the braking could be better and instead of replacing the master cylinder with a 17mm I thought I'd upgrade the front calipers.
From what I can tell early 911/912 calipers for solid rotors will be a direct bolt on to the early 914 strut. I also think they use the same brake pad. Has any one done this or can someone confirm that they will be a direct bolt on and is the pad size the same? thanks -Rob |

QUOTE the "M" caliper for solid rotors seems to be a good choice They bolt right on. Good choice? Same size pad with a 48mm piston vs. a 42mm piston. You're not gaining anything in friction. Just screwing up the bias with the rears. QUOTE less force on the brakes than with the 17mm Well... it actually takes more force to operate the pedal but, that's negligible at this point. I would replace any 17mm with a 19mm at this point (if it needed to be replaced). QUOTE IMO - if you want better braking, just get a better class of pad. Porterfield R4S are the hot setup. A solid-rotor 911/912 caliper will be OLD, and cast iron. You're better off with what you've got - just use a decent pad. I had an early ('65) 912 and I don't think its brakes were even a little better than a 914's... (IMG:style_emoticons/default/agree.gif) What she said. (IMG:style_emoticons/default/biggrin.gif) 914 brakes in tip-top order with killer pads should rock any narrow body world. Are they gummed up? Do they have old soft lines? Is the venting clearance set on the rears (most are inoperable)? Did you bed the pads? Even old pads can be re-bedded and you'd be surprised at the difference. Those Brembo's in the classifieds are the hot set-up but, you'll need vented rotors (or, there's a guy selling his that have the spacers removed... bolt on for your car. PM me for his details). The problem you'll find is, there's a "lot" of pad there for a solid rotor. Time to get some cooling in there. Most people would benefit from a thorough system rebuild (top to bottom), new pads and new tires. Best... E. |
