914 rear brake upgrade

efeinsmith · 05-09-2001, 10:36 AM

As the transplant project continues, I'm setting up the braking. In front, I have 911SC parts from the struts outward includ-ing cross drilled/vented rotors. For the rear, I plan to use BMW 320i calipers (the BMW caliper has a considerably larger piston and pad area than the stock 914 rear caliper). Its a popular and fairly inexpens-ive approach for the front, but will fit the mounts in the rear. For the emergency brake, I plan to use a Wilwood standalone park brake (that mounts opposite the brake caliper). The only dangling issue here is to fabricate a mount plate for the Wilwood unit. Has anyone had experience in this arena? (and yes, the proportioning valve has been replaced with the "T"). Thanks.

I did the same thing on my race car and it took a couple of trys before I made a bracket assembly strong enough to keep the small brake from bouncing around and self destructing. I ended up using a rear backing plate that I cut so the caliper would fit over the rotor and then making the locator pieces and braces from 1/8 x 1 and 1/4 x 1 steel stock. I also had to reglue the stationary pad with 600 degree epoxy as the glue that was originally used melted and the pads disintigrated! Finally I had new e-brake cables made which were about 11 inches longer that stock. There is a picture with the article I have here on the PP site. Good luck.

Now here is an answer to my Questions! Although it brings up more questions!! Where can I see/learn more about the Wilwood Standalone Parking brake? Do I follow correctly that this mounts inside the existing rotor or somewhere else? Thanks for any help....checking Johns article now also......

If you are in southern CA then give CNC Brakes on Morena Blvd a call and Chuck can fill you in. Otherwise check out Wilwood's web site and they are listed, but have absolutely no info on how to mount them. If you decide to try one, I would order several extra pads from Wilwood for the caliper and find some 600 degree expoxy and reglue the fixed pad since the factory glue doesn't hold well at all. Hi temp epoxy can be found at adhesives supply stores listed in the Yellow pages. For info purposes, it took me a full day to make the mount since there are no patterns. Good luck.

John,

Yes I'm in So Cali....N. SD County actually! I saw your 914 at the Murph...uhh at the Q back a month or so ago! Nice stuff there! Anyway, about the brake...thanks for the info, I'll stop by when I'm down that way and check it out...I'm not too worried about the fab work, thats the easy stuff for me to take care of! I just knew there had to be a way to put an aux E brake on there! Thanks so much!!

Craig.

This is an old thread, so I hope someone is still reading! I've been trying to find John Rogers' tech article and photo of his Wilwood caliper installation on the Pelican parts site. Is it still there - I can't see it. Any links gratefully received. Thanks

Eric,

Another option is to use the 911 SC or Carrera rear rotors and calipers.

Jim,
Could you give me details of the CV joint adaptors you've mentioned in other posts. What years they fit (914 and 911) etc. Or point me in the right direction if the info. is already posted.

Apologies if it's rude to butt in like this - it is rear brake related!

Thanks
