Can I go with the 10x1.5 rear drums and shoes??? I think I have the 1.25 shoes right now, but more surface means better brakeing, right??? Just a thought before I buy the drums and shoes and start this project. Thanks for any advice/info.------------------

68 coop,
First Mustang Rule: THEY DON'T STOP!!!!
Drum brakes are drum brakes,period. If you really want to stop, switch to discs or drive slower and leave lots of room in front!!!
My 67 fastback has drums, as did all the other Mustangs I've owned over the years , and I haven't had any problems with stopping----I just keep reminding myself "it's a vintage car, so slow down". Besides, driving slow gives people more time to check out the car!

Yeah, I wasted a set of Goodyear II's one night because I locked it up and slid about 100 feet. Just curious if I can go with the bigger drums and shoes on the back without any problems. I want to do all 4 wheels soon, and I have the front already. Thanks for the advice Jay.------------------

Did all 4 wheels lock up or just the rears ? If it was just the reas maybe lok into adjusting the brake bias a *little bit* so they dont lock up as quick and practive threshold braking. THats when you push the brakes until they are about to lock up then you let them go slightly. Im sure someone will have a better description of how its done. As you know locking up the tires isnt such a good thing, and just because you can doesnt mean you should. YMMV... David F.

That happened just shy of a year ago, and trust me it was not intentional, a herd of cows were on the road. I've pretty much got them down as far as stopping now, I just want to know if I can go with the same size drums and shoes on both front and back??? Right now they are a 1/4" less on the width on the back, so if I buy the bigger/wider ones, will they fit the same??? I can't ask the counter people at the Zone, they don't know.------------------

I think the trick setup for rear drums is to use fairlane or station wagon drums. This is what Shelby did in the early years, IIRC. The only difference is the wagon drums are slightly wider, as you noticed, and will help you stop better w/o fade.

It can certainly be done William, and is a good upgrade. Mustang rear brakes went wider in 1973. I have a set reserved for my 68.
Personally I don't share jay67fast's dislike of drums. On mid-size cars like 68 Stangs they can give really good stopping power under most circumstances. For safety's sake, discs are good on the front, but I think for daily driving they are overkill on the rear.

Thanks Simon, that was the answer I was looking for, I hope. So, just so we're on the same page, I just get the drums and shoes like I was doing the front, but put them on the back. Just want to be sure. Thanks to everyone who took the time, it is greatly appreciated.------------------

Aaaah, you mean you're planning to put a set of front drums on the rear? That won't work at all. I can't remember why offhand! It will come to me in a minute!

Might have something to do with the bearing hub.

Fastback68,
I haven't any idea where you got the idea I don't like drum brakes---as I posted I have had drum brakes on all my Mustangs. If I disliked them I would have replaced them with discs. They're fine as long as you don't overestimate their effectiveness.
Drum brakes are just not as effective as discs; they are what they are!!!

Just to complicate things, my 67 coupe has Torino station wagon backing plates and finned drums on the rear. The fronts are standard 4 piston Kelsey Hayes "grabby" power discs. It stops okay, but still have to be careful because of the grabby feature.------------------

The last part of the link:
"I don't have any scientific data for whether or not this conversion really
helps braking, but I can say that when I had 4 wheel drum brakes I was on
more than one occasion literally scared for my life. Since converting the
front to disc and putting bigger brakes on the back, I am 100% confident in
my Mustang's braking ability and have had no problems at all with getting it
to stop." My brake setup is very close to his with the Torino station wagon rear brakes and 4 piston Kelsey Hayes front disks. It stops okay on normal driving, but you have to becareful when slamming on the brakes due to no anti lock features. I had to slam on the brakes once at freeway speed in the fast lane when someone cut me off and decided to slow down really fast! My rear end came around the right side as the front discs locked up. Luckily no one was in the right side lane. I also know what the author means about 4 wheel drums. My 65 coupe rear ended another car and I really wasn't going that fast! In summary, you just have the drive more carefully with these old school brakes. ------------------
