Rear Brake Caliper Options w/ 911 Park Brake Options

[gryphon68]

What is the best match for rear brake calipers if I am planning a 5-lug conversion with 1970 911T Struts and hubs? Leaning towards the 3" Brembo Aluminum calipers in front, the lightweight is a big plus in my opinion.

Hoping to use the 911 parking brake in the back, so no need for complicated rear calipers with internal parking brake.

Besides a 3" M-Caliper (38mm?) what are the other options for the rear calipers?
Something lightweight would be a bonus . . .

If I where to run a dual master cylinder pedal with balance bar would it be possible to just use another set of the 48mm Brembo Aluminum calipers on the rear?

911 brakes boil down to the different connections and cables required for these brakes vs normal 914. Do talk to Eric which I believe is the best source for this information.

Do research on this board and you will find a wealth of information.

Tangerine Racing has a modification to the 914 cables which adapt to the 911 brakes.

You can make the 911 e-brake work, but it's a bit of a sucky set-up in a 914.

I'm going to be running the same front set-up, IMHO run the stock 914 rear calliper with drilled rear rotors and 5 bolt hubs (modified 4 bolt) or do the V-caliper if you really want to run vented. For the v-caliper you need Eric's kit (or finished v-caliper) and you need to trim a bit off the 911 rotor.

Unless you are racing the un-vented rotor system is good enough.

My v-calipers are nice, but came with no hardware (pad pins)...and Eric never returned my e-mail so I'm having to make my own hardware.

[gryphon68]

Not really asking about how to make the parking brake work. I'm asking about the non-parking brake caliper options.

Thanks!

I'm runnng the 911 e brake with standard Boxster calipers front and rear. I bought the adapters from Richard Johnson. He is in the members vendor section. The brakes are probably overkill, but I love the braking, balance and most important doesn't squeal like the 944 turbo brakes I had in the front before.
I think my front struts are 3.5" spacing though..

PMB Performance also has new aluminum 914 style rear calipers with the parking brake built in if you want weight savings and ease of installation. They are a bit spendy, but worth every dime.

I may be changing out brakes to something bigger than I have and putting my Brembo AM calipers up for sale if you're interested.

I bought mine from Eric and they are a piece of art! In my opinion, why reinvent the wheel? He has every option to keep the parking brake and have good brakes for a fair price.

Oh, did I mention he is a great guy?

I'm not sure using 911 parking brakes qualifies as reinventing the wheel . . . .

It's a matter of personal preference I guess. Eric Shea has admitted himself that integral parking brakes can be a love/hate thing and that because of the parking brake many of the 914 rear calipers being used on the road today are NON-functional. I personally don't like the failure modes that the integral parking brake causes. Having a separate parking brake, in this case 911 drum-type, has more appeal to me.

Watching this closely as I am going to need a set of rear calipers for the same setup

[DRPHIL914]

definitely talk to Eric. I just went thru making this decision, as i had purchased the group buy 5 lug conversion. Eric explained bias, balance and what goes with what.
I was looking at 'M' calipers etc but for the expense you really don't gain that much advantage. the stock calipers as he will tell you do an excellent job stopping the 914 when new or rebuilt.

In the end i ordered from him stock replated and rebuild calipers for front and rear. They are original to the car and with the correct pads do an excellent job, even on the dragon . - larger pads have more surface area-more friction, more heat- Eric convinced me that properly functioning stock calipers were just fine for me even if i do an occasional a/x, not worth spending 4x more for a slight (maybe) gain

good luck

If properly bedded and adjusted they work great.

2lbs. 12oz. light enough? 38mm pistons are the perfect bias for the fronts.

http://www.pmbperformance.com/catalog/item...645/9768541.htm

No on the balance bar MC, you would only be able to pull the fronts or rears out of the system. With the 38mm pistons you have the prefect bias match for the 48mm fronts.

For $100.00 more I'd just go with the proper 914-6 rear calipers. Love for me, hate for others who don't want to or know how to maintain them. They're a great caliper that should be simply adjusted once a year when you inspect your brakes and change your fluid (right?)

If you don't want a handbrake, fine. If you do, it would be cheaper to run the 914-6 route vs. doing all of the mod work for the 911 handbrakes.

I think it's funny that a $699.00 "pair" of calipers is spendy. (IMG:style_emoticons/default/lol3.gif)

[CptTripps]

I'd love to have a proper handbrake, but I'm going to be running the Boxster calipers, so I think I need to go with the "modern" brake-shoe drum setup. Right?

[tomeric914]

Why's that funny? (says the person who has thrown you a lot of cash)

I did say they were worth every dime. (IMG:style_emoticons/default/KMA.gif)

[Eric_Shea]

Because, that's really cheap for a pair of calipers.

Not sure how much cash you've thrown me has to do with it? I just think it's funny.

That's $350.00 each caliper. Pistons alone go for $45.00 each so now, $260.00 each. Then there's raw materials, molds, castings and machine work, anodizing, fasteners, seal kits and labor to build them. What's that boil down to? Even if you divided all of those remaining processes out evenly that would be $32.50 each process!! Nobody here could do all that for $699.00 Yay/Nay?

These are pricey:

[tomeric914]

Fair enough. My "spendy" comparison was to FLAPS rebuilds for $100 each that are no where near your quality, not to mention that your aluminum versions are new. Some can't afford the initial cash outlay, others are shops repairing on the cheap to make a profit.

Bottom line is that your stuff is worth every dime, and the reason I keep coming back as well as referring others to you.

[jcd914]

I have been thinking the Aluminum Brembos on my 911T front struts with Eric's Aluminium 914/6 rear calipers should be a prefect set up. More brakes than my narrow body 914 will ever need, in a 205 width even sticky "race" tires will only provide so much grip.

Not cheap as in a couple hundred bucks but for a good brake set up it is cheap.

Save on un-sprung weight and get a balanced brake system that is bolt on.
