I'm running into an odd issue, and I have yet to pinpoint the cause. randomly, the car will start surging quite badly, with seemingly no outside input.

Does the DBWX2 figure how much idle opening is needed on its own?
Does the MS3 send an idle opening order to the DBWX2?
LOL... So putting all the effort I put into my hot rod parking brake was totally well spent (Damn, there's no maniacal laugh emoji)ericjon262 wrote: ↑Thu Jan 20, 2022 12:58 am
I recently discovered that Wilwood manufactures a drum in hat parking brake designed to fit under several of their hats. I've been considering developing a new set of knuckles for the car to accommodate a better(lighter) brake package, so I may shoot them an email and see if they have any useful drawings they I can use for my development. I suspect they will decline, but who knows.

I haven't investigated it much further than seeing they exist, and getting a link, I've been looking at two piece rotor options, if I'm gonna do it, may as well do it all the way.The Dark Side of Will wrote: ↑Thu Jan 20, 2022 12:04 pm LOL...

Searching the rotors comes back with these results:

Quite a few of them caution that they are for drum-in-hat parking brakes. None of them are what I'd call cheap.
E.g. https://www.wilwood.com/Rotors/RotorPro ... =160-10049
This says that the shoe dimension is 7.24". I guess that's workable inside a 12.19" diameter solid rotor, but it's pretty big.
My unit has a 6.615 (168mm) drum ID which makes enough annulus to have the bolt circle for a two piece rotor in between the P-Brake drum and disk surface.
Lol! There are things I enjoy, fixing a broken 2mm bolt is not one of them...The Dark Side of Will wrote: ↑Fri Jan 28, 2022 7:59 pm Don't you brag about machining everything yourself at work?![]()
Interesting that Rock does not list headlight motors.
They're metal as far as I can tell, I didn't try scratching paint off or anything like that.pmbrunelle wrote: ↑Tue Feb 01, 2022 7:28 pm Are the cases of those new motors aluminium, or painted plastic?
Think they're more likely aluminum or pot metal?pmbrunelle wrote: ↑Tue Feb 01, 2022 7:28 pm Are the cases of those new motors aluminium, or painted plastic?
I don't know, they could be either one I guess.The Dark Side of Will wrote: ↑Wed Feb 02, 2022 10:19 am Think they're more likely aluminum or pot metal?
