Which Brakes? Which Car?

[TylerEss]

Does anybody have the information as to which brake systems came on which cars? I'm aware that 88+ Turbo II cars have 11" brakes and the vented rears, and that R/Ts do as well... not that parts cars of those models are easy to find. I also know that all cars have 4-wheel discs of some sort or another after 1988. I know about the "SLH" packages using the minivan brakes. That's all I can find on the internet.

Is there a big table somewhere that I'm missing that shows which brakes came on which model/year pairs? If there isn't, then start posting the info up from your FSMs and I'll compile it myself!

I'd love to swap the car over to 11" brakes, but it's hard to do when I can't find the information. It'd be awesome to help create a resource that would be useful for quite a while to come.

I think this is what you are looking for.

:-) Are the minivan brakes more powerful than the 11" ShelbyZ-R/T brakes? Are they significantly more powerful than the 10.25" brakes that come on everything after 1988? Where else can I find 11" brakes?


Thankyou!

I think the main purpose to the mini-van brakes is the "improved?" cooling - more vanes on the disc. As well as the beefier (thicker) rotors so you lessen the chance of warping them. Also you won't have to replace them as often!

no, caravan rotors are thinner to allow for thicker pads! the late 80's caravan 60mm kelsey hayes calipers w/ 10-1/4" rotors are less than the R/T 60mm/11" brakes!!!

the early 90's dynasty chassis cars have the 60mm/10-1/4" setup only the rotors are the standard thickness and the calipers are the dual pin setup like instead of the single pin like the van brakes. if you go with these, there's no reason to go bigger than the solid rear disc. if you go w/ 10-1/4" rotor brakes and solid rear disc (or smaller) 14" wheels will fit. dynasty will also have the van/4 disc car 24mm master cylinder

only reason to bother w/ R/T vented rear disc is if you are using the corresponding 11" front brakes, otherwise the additional weight is not worth the gain (if any). rear disc brakes only give you about a 10% increase in stopping power (but not necessarily reduced distance). most of the braking power comes from the front. rear disc is most useful in performance driving or trailer towing (which i plan to do with my k wagon).

my cars-

1989 Spirit ES 2.5 T1
dynasty front brakes and m/c
90 spirit es solid rear disc and prop valve
(i will be able to use 14" wheels as spares)

1986 Aries wagon 2.5
Spirit R/T 11" front and rear vented disc and prop vavle
24mm m/c
(will not fit all 15" wheels, i'm using Neon SRT 17")

Mmm. Awesome. This is most helpful--the 90s Dynastys have the same brakes, basically, as the minivans, as well as the 24mm MC.

I'd really love to just swipe the brakes off of a Spirit R/T, from the MC to the calipers, should I ever find one; I'll just be looking for the Dynasty brakes until then. I'll be driving the car just about every day, but I'd like to drive the hell out of it sometimes, too.

For those following along from home, I re-found a page I had already seen that has just about every question I was wondering about:http://minimopar.knizefamily.net/perf/brakes.html
Thanks for your awesome input!

I have a set of rear calipers off of a '91 Y-body that have 36mm pistons in them(the same as 11" brake set-up), but used solid 10.25" rotors and drum style e-brake....It worked VERY well with the minivan front brakes...

[capev86]

i have heard of the larger piston / solid rotor package on the large chryslers, but they are not as widely know about as the the 34mm/solid rotor and 36mm/vented rotor systems. the caliper may have the same piston size as the r/t brakes, but id gather the "gap" on the caliper is gonna be smaller because it doesn't have to span a vented rotor.

i'd be interested if that car has 14" or 15" rims. the regular solid rear disc will fit 14 rims and the r/t vented rear will requires a 15 inch rim. the r/t front brakes dont even fit all 15 inch rims (pizza, swiss cheese, etc).

also, i grabbed the 15 inch space saver from my dynastyfor use on my k wagon because it will be running r/t brakes!

There is another option for the rears that nobody seems to talk about.

I replaced the rear wheel cylinders on my SC with WC370051 wheel cylinders from a 1997 Caravan. The two wheel cylinders don't look the same and you will swear they won't work but I have been running them for some time now and have had zero issues. I know there are others out there running this same rear setup. I have 1990 Daytona Shelby front brakes on my car as well. It is a night and day improvement in braking. I did upgrade to the 24mm master cylinder as well.
The Later Daytona Shelby's and R/T's have more pad swept area than the smaller Caravan setup. Like others have said there is some modifications to the spindle that have to be done to bolt this setup up. With new pads and this setup 1/8 inch wheel spacers are necessary for clearance with 15 inch wheels.
The part I like is it is a bolt on and adds practically no weight. The benefits are evident the first time you make a panic stop.

The Y-body rear 36mm disc set-up requires modification to the adapter plate(the holes for the spindle are farther apart). The spacing for the caliper to adapter plate is different than the 11" set-up, and is also different than the regular solid disc caliper(due to the larger housing for the larger piston). Whether it will fit 14" wheels or not...I really don't know. I had 16's on the car the whole time and the car in the yard didn't have wheels on it IIRC. They "might" clear, but a test fit would be required.

Another rear brake set-up that nobody has mentioned is the AWD Minivan set-up. They have discs too, but they require the larger bolt pattern and possibly other things to make it work right. I've never really messed with one in person...

[capev86]

the 36mm/solid rotor system is supposed to be on dynasty based models around 1989 or so. i think it was mentioned in some of that slh literature which i haven't really gotten into lately because it is not complete!

[Reaper1]

All I know is what the set-up came off of. It was definatly a New Yorker...
