<p>I wonder what Jaguar's electrically actuated parking brake weighs.</p>

And if you are some other company that sells a Wilwood rear caliper set-up and add a parking brake it increases the cost by about about 41% (still want, though).

What I am psyched about is this is being worked up to keep a good F/R bias balance.

No further details on products for the rear for the time being. Naturally, lots of track testing before anything gets a green light, I don't want to make any hard promises on a configuration that may change during development.

Upgrade to DynaPro 4-piston fronts!

<p>So I stuck some BP-10 7112 in my dynapros last night, and the hole where you put the cotter pin is way bigger than on the dynalite, do we need a bigger cotter pin?</p><p>This picture might explain it:</p><p>https://www.miataturbo.net/attachmen...ine=1441400790</p><p>See how the cotter pin like fell all the way through?</p>

What about this?

More reusable, too.

Would not fit through pad. There is a spring clip I think 949 sells.

Doesn't have to be that big. Looks like a 6-32 or 8-32 would fit. Drywall anchor screw size, long enough and usually pan head.

I'm going to do something like that. I don't want a bagillion cotter pins.

For 7112 in the Dynapro you need 2 cotter pins per caliper, in the two outside holes, no use for the center hole as on the Dynapro that hole is for an optional bridge bolt, not a cotter pin. The Dynapro doesn't have pad keepers on the bottom, so the height of the pad in the caliper is regulated by the pins alone, thus the need for two of them.

Could I drill out 7112 center hole for a bridge bolt?
<br />Only asking because G is giving me a set of 7112 bp-10s and they don't have the 3 hole.

The bridge bolt is not intended as a slider pin, so while you might be able to drill out the backing plate for a bridge bolt to fit through, that doesn't satisfy the need for locating pins for the pads to slide on.

The ability to run some 7112 pads in the Dynapro is a big deal for expensive/top-tier compounds that aren't available on 7812-specific backing plates (Dynapro uses 7812). A BP-10 is like, $35-$45, and available in both 7112 and 7812. Really no reason to try to mickey-mouse the 7112 version into working in that case.

Except these pads were free, and free is cheaper than $35. But point taken.
<br />What's the bridge bolt for.

I can't argue with that ;)

What's the bridge bolt for

"Bridges" the gap between the two halves of the caliper. Adds rigidity. It's a bit of an afterthought on the DynaPro and not very necessary IMO. It's already significantly more rigid than say, the Dynalite.

<p>Question for someone who had DTC-60 7112's in their hands.</p><p>Looking at hawk pictures for the DTC-60 in 7112 I don't see the 3 holes. Is this an error, or is the DTC-60 one of the pads that doesn't have the 3 hole backing.</p><p><img src="http://cimg3.ibsrv.net/gimg/www.miataturbo.net-vbulletin/792x792/80-hb540_d90676d618d1826fcc9da9e61c5ae50646459ee2.jpg " title="" /><br /><br />&nbsp;</p>

If I run Dynapro's in front with PFC01s what pad do you recommend I run for my rear Sport brakes?

Thanks!

Looking forward to seeing this rear kit.

PFC01 in the rear. Get the standard 1.8 rear pads and with a little backing plate shaving they can fit the sport calipers. I don't have pics of the process since none of us run the sport rear caliper here, but lots of guys have done it.

Is it safe grinding the backing plate down with power tools? A post in the big brake thread recommends using a hand file:

I plan to install my new Dynapro and PFC01 combo later this week and would much rather use power tools to modify the backing plate.

Johnny (OGRacing) is our distributor for PFC pads and the one I consulted when originally looking for a PFC option for the Dynapro. Grinding the backing plate to clear was his suggestion and also got the OK from a PFC engineer.

Thanks. I was not looking forward to filing that much material off by hand.
