Just kidding with you guys (IMG:http://www.914world.com/bbs2/html/emoticons/wink.gif) I currently have a 19mm master and M calipers up front and went through some of the same things after I initially made the changes. Can't wait to run with you both at Buttonwillow. (IMG:http://www.914world.com/bbs2/html/emoticons/beerchug.gif) |

update....
got the brakes bled and pads bedded in. everything seems to be in order. Tested from 50 mph stop. no rear lockup (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif) At least I know it will work around town...now for the track in a couple of weeks. I love it when things work out (IMG:http://www.914world.com/bbs2/html/emoticons/huh.gif) I knew you were just kiddin' Greg....What rear brakes did you go with? Stockers? |

Porterfield R4E for the front and PBR stockers for the rear.

I still have the stock rear calipers. (and the emergency brakes work too!) I had a couple different plans for upgrades but as I keep taking weight off the car.... The brakes work better & better (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif) so I'm thinking I don't want to add any more unsprung weight through bigger rotors & calipers if I don't have to I actually have a set of early 90s Big Blacks & Carrera front struts ready to bolt up when & if the time comes |

Shoot me if this is a hijack, but all this talk has me curious about my planned setup. S alloys up fron stock -4 in the rear, 19 mm MC, and a T. Yes/No/Maybe?

With the T you should be fine... it would be nice to have a slightly larger piston back there but, those come in 2 varieties:
914-6 - Expensive 911 - No handbrake, unless... |

I use the M calipers in front and BMW in the rear with Porterfield racing pads in front and the Axxis semi metalic pads in back and I too found that braking from 50 or 60 MPH was fine but from 135 it was a whole different story. The front pads need to get hot before they work well and the rear end danced a lot. I put in a manual prop valve and have the rear cut out by about 30% or so. This only happened at the CA Speedway as they use running starts and the pace lap is not enough time to get the front pads up to temp, even ridding the brakes some. I also found that when the front pads got really nice and hot that the front would drop really fast so I had to set the Koni front shocks really stiff. All other tracks I run them full soft.

I think I remember this....deja vu all over again (IMG:http://www.914world.com/bbs2/html/emoticons/ohmy.gif) (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif)
Thanks for the info John... That is what my test day at BW will be all about. How much do I need to heat up the fronts before the work really well and then do I have too much rear bias.... |

(and a spooky voice from the dark said... M-calipers in the rear with a p-valve and the same pads all around) (IMG:http://www.914world.com/bbs2/html/emoticons/laugh.gif)

Just to throw my setup in the mix: A calipers in front, M calipers in rear with vented SC rotors. I have adjustable bias valve and run Pagid pads. I never have brake issues so I can't complain. No emergency brake, but I don't plan on letting my insurance company know. If they ever saw a picture of my car it wouldn't much matter about the e brake!

4 bolt set up with 3" spacing is what I run....so I am limited to my choices. (IMG:http://www.914world.com/bbs2/html/emoticons/rolleyes.gif)

Dan,
Here are the big blacks I had setup for my 914. Another option for 3" spacing. Again I haven't done this yet since the weight loss program has taken away some of the need for bigger brakes. Remember Newland's car? He ran the Alloy S calipers and never had to go bigger... Attached image(s) |
