87 Shelby Z brake upgrade

[Bl4ckD34m0n]

Alright guys, I'm sick of the crappy selection on pads with these 87 single pin calipers and their constant rattling. What parts do I need? The car already has a master cylinder designed for 4 wheel discs, solid rears. I can probably figure it out on my own, but any help will be greatly appreciated. 11in parts are too expensive, I'd rather just get a good 10.25in setup, I know minivans had the good brakes, but what models and years, some guys are telling me all minivans had them, but thats obviously not right, since there are 4 different part number sets for Caravans from 89to92......I'm heading to a u-pull it yard tomorrow afternoon, I've prices the parts avalible at my local Autozone (which I get a discount at as a weekend worker now) and everything after the cores should run around a hundred bucks, for Calipers,good pads, new rotors, and hoses, I'm going to search for good parts at the salvage yard as well as theproper mounting brackets, as well as some good rotors.
Here is what I thougt I knew.
Minivans w 15in wheels have the good HD brake setup, so far, all calipers I can find online for minivans with the larger wheels are the 2 pin style KH calipers, and the only single pin calipers that some insist are the good ones are the ones for the 14in wheel vans.
I have also been told by some that 1st gen G-body control arms will not bolt onto the needed caliper brackets.

Thanks guys, I'll be sure to update if I run into any odd problems or find some good solutions.

I do not remember exactly, but I know for L-bodies, the SLH setup goes through and talks about upgrades. If you look at the write up for the SLH, there is a section that talks about the minivans. I do have a rear end setup of 11" discs that I am thinking about getting rid of.

since I have an 87 shelbyZ that at one time had stock brakes let me chime in here. I had the big minivan fronts and stock rears. The braking was very unbalanced. The fronts were so effective they would lift the rear tires off the ground. Upgrading to full 89 11" spec brakes has the car squat down on all fours and come to a hard flat stop. I'd keep the stock brakes until you can afford to go with an 11" setup.

ok, I can do that, I was just trying to avoid the extra work, I have 2 complete sets of rear late model vented discs sitting in the garage, just limited time, (working 2 jobs to pay the bills) so I guess my question is, what is required to swap late model 11in rotors and calipers onto an 87 g-body, the ball joint PN's are different, so I'm assuming the late model knuckle won't fit, so am I looking at a complete control arm swap to accomodate the bigger rotors, or are the early minivan KH calipers significantly better than the stock Z calipers, I know they have a better selection of pads.

PS - I may have located a late model g-body donor car, my dad took a full set of vented rear discs off of it last weekend, and the fronts were still intact a few days ago when he visited the yard again.

11" R/T calipers were ~17$ rebuilt at autozone last I checked, rotors are ~$25 each at napa. I dont think thats expensive. Rears are more, well calipers as the rotors are ~$25 also.

Comparing to $10 10" rotors which you should already have a little more expensive


Hey GLHNSLTT2, was that w/ the stock prop valve? I think my car behaves similar but the rear is very lightened

OK since you posted when I was typing, the 91+ have different arms and ball joints of course. If you want to swap most recomend switching the complete K frame/arms/knuckles and swaybar as there specific. It all bolts up and all 91+daytonas have the 11" R/T brakes(I believe rears also?) And like I said if you look around a little the prices are not much different

[1983Rampage]

all you need is the front calipers, caliper mounting bracket, and rotors. And you will need to grab the prop vavle, since it is different from the one that you have. But you could use your old one, it just won't have near as much pressure to the rear.

[Bl4ckD34m0n]

so the 87 4wheel disc master cylinder should do the trick, hmm, god I hope that g-body is still intact.....wtf, the autozone website only offers loaded pairs of the front calipers for the late model daytonas with or without disc brakes.....uhh, wtf? - NM, the website is retarded. I see them, hmmm....I want them now!!!

[speeduphoria]

I was under the assumption that the rear drum prop valve was more pressure to the rear because drums are not as affective and from the prop valve info on one of the SLH pages and from people talking about locking up the rears early w/ the stock drum prop valve on swaped rear discs. Daytonas had the same valve for drum and disc, maybe I have this backwards, I'll have to go check up on the info.

Also I thought that since the 89 and 91 knuckles were different that the newer calipers wouldnt bolt onto the older knuckle, hence the reasoning for GLHNSLTT2 saying use the full 11" 89 brakes which include the caravan 11" fronts and some 11" rears(as all the 11" rears are the same iirc). But again I may be very wrong.

87 Shelby Z's had 4 wheel discs from the factory, 10.25in Vented fronts and Solid rears, the master cylinders are different, so I assumed the prop vavle is. Like I said, I have 2 complete sets of rear 11in vented rotors, and the part number are different, calipers, hubs, ect, ect ect.
Hoping the front brakes on that late model G body are still intact. I will grab the prop vavle from the late model g-body if it is there.

If by chance, could I get you to see if there is another prop valve for the same style of vehicle. I wouldn't mind having one for my nice new setup from FWDSleeper. If you can get another one, just let me know. Matt

lol, NP man.

Ok, parts update:
Donor Vehicle: 1990 Dodge Daytona ES 3.0 V6 5 Speed tranny w - w high performance handling package package. 11in front rotors and Calipers, Single piece caliper brackets/knuckle mount, Vented Rear Discs, new rear rotors, and calipers, good e-brake shoes, Anyone know if they make a ceramic or Carbon-Metallic performance pads for the front and rears on this car, all I can find is Semi-metallics, both front and rear. Ohh, and it had a fully intact Master Cylinder and Prop Valve, got em too, the only ones in the whole yard for FWD EEK 4wheel disc w 11front and vented rear parts. Gonna hit up another yard tomorrow to look for some more parts.
AZ and AdvDisc brake pads PN#'s
Front - MKD416 - Semi-Metallic, buying new, looking for Carbon-metallic or ceramic replacements eventually.
Rear - MKD414 or 415, Semi-metallic, Buying New, looking for same as fronts eventually.
Looking for good used front 11in 5x100 rotors at the yard, found locally for new at NAPA for about 32.bucks ea, can get em if I can't find good used units.
Have good rear calipers, hoses and rotors.
Will grab any prop valves I find for big brake 4 wheel disc's, if I find any more.
Am I missing anything? Any good parts on a 90 oddball V6 w a 90's version of the CS package, I'll bring my calipers and measure some parts, tomorrow.

PS, AZ lists that both the Shelby Daytona and the 3.0L V6 Daytona ES Matching clutch sets and the 18 spline, 9in, 13/16 HD clutch that was used on the early 568 trannys.......I wonder what this oddball has....

[1983Rampage]

well, the 3.0 5 speed is a 543 and the 523 and 568 are all in the same family, so having the same clutch really does not suprise me all that much. If you can find a set of rear brakes lines as well, i would take them too along with a prop valve. Thanks for looking though. Matt
