I'm toying with the idea of pulling the rear drums and replacing them with disc brakes. I figured i can get the parts from a zx2, and rig up new brake lines and a master cyl. What do you guys think?

I think most ZX2s have rear drums.

You can grab the rear spindles, calipers, flexible lines and e-brake cables from a 2nd gen GT or a ZX2 S/R and it should all bolt right up. If you want you can bolt in the entire rear subframe from an S/R since '91+ all use the same floor pan.

I don't think you need to change out the master cylinder unless there is a preload valve built-in for the drums :?:, which I don't believe there is, since they use ratchet adjusters.. *not certain* :x

I'll be doing this myself when the finances allow.

...

i haven't actually taken a look at the setup, actually i just thought of doing this a couple of hours ago :) Doesn't seem to be that bad of a job though, as long as i can get my hands on the parts. I've never done a full conversion before, but i have installed disc brakes on my old car, a '91 sable wagon. Pretty easy job.

I collected the parts I needed to convert my old BMW e21 320i to rear disc. It takes the entire rear control arms from a european e21 323i. By comparison, the escort is already 50x easier and cheaper to upgrade :lol:

Be sure to tell us how it goes.

If you haven't already made the change I've heard rumors there are severe duty/fleet calipers out there somewhere.

I'm checking with a buddy that's a Ford tech and may know later today if they're worthwhile.

Supposedly Pep Boys has them, I just want to check with the Ford guy to find out if they're the real McCoy or a Pep Boys pipe dream.

Anyway good luck onyour project.

I wish someone who already did this would write a nice "how to" article.

Also, I'd wish they include if the brakes work any better because when I test drove both cars (LX and GT) in 1995 I could not tell any difference.

They work better, it's a given.

Calipers keep pads a more consistent distance from the rotor over time than drums do their shoes, keeping a more consistent pedal over time.

Calipers shed heat and pad gasses/particles much more easily than drums, which trap heat and brake-dust inside, resulting in less fade.

Disc brakes are easier to modulate when threshold braking, thanks to their simpler mechanics, and perpendicular force against the pad (drum brake shoes don't get shoved against the drum with a perpendicular force, and can bind up enough to keep a locked wheel from rotating again)

Since most of your braking in a FWD car is done by the front brakes, they pretty much determine how well the car will stop during a test drive. It's when you're flying down a mountainside for 20 minutes, about to burn up your brakes that you'll be glad you have 4 wheel disks. If you could tell a difference during a standard test drive, then most people would stop buying cars with rear drums.

I have thought about taking the rear suspension cradle off of my 94 gt and putting it on my 02 ZX2. as far as I can tell it should bolt right up. I hate the rear drums on my ZX2 - why did ford do this? the 2nd gen gt and the zx2 are really the same car with different sheet metal.

I'm not disputing that discs are better, they certainly are. I was just noting that during my test drive I could not tell any difference. I think if I ever need a major repair to my rear brakes I'd like to convert mine.

In addition to a How to article, a list of appropriate donor cars would also be helpful. I'm guessing it's easier to find a mid 90's Mazda then a 1991-1996 EGT to use as source material.
