1992 Mustang Rear Drum Brakes

If your Mustang has sat for a really long time or if you swapped rear ends from another car it's best to check the rear brakes condition and road worthiness.

The rear end in my car is from a 1992 GT mustang. This car has been sitting for many years, so I popped off the rear drums and inspected them.

It's a good thing I did Here is what I found.

Upon closer inspection the both wheel cylinder seals on both sides of the car were dry rotted. This meant tearing the whole system apart and since I was doing that it seemed logical to replace everything. 

On one side a brake bad was cracked

While I was inside and had things apart I decided to clean some parts up and add high temp paint. 

Now putting things together can be tricky on the last spring, but I have a tick to help out with that.

The last piece is the adjuster stop and it has a tendency to pop out when trying to install the last spring. My cure for this is to take a 1/4 inch socket out of a 1/4 inch drive socket set and shove it the hole that the stop is hooked in this will hold the piece from popping out as you work on getting the last spring hooked on it. 

Since I have much wider and bigger wheels than I had from factory now. I grabbed these park brake cable guide brackets off a newer mustang in the junkyard. I cleaned then up and Plasticoat dipped them. 

I have no glass or interior in the car right now, so she is riding a little high. 

I was already going into the rear of this car since this is what was left of my original park brake. 

I now have a functional park brake.

1979 Ford Mustang Brake conversion from 4 cylinder to V8 brakes

Now that I am finished with the suspension it is time to address the brakes.
This has been a long time need for this car. It started it's life as a 4 cylinder and ended with a V8, but unfortunately it never had the brakes upgraded. It was all go and no slow. lol Who needs brakes right, there overrated.

I am on a budget, so I am not going to put sn95 spindles on the car or convert to 5 lug. I scored a lot of parts from a guy I met at Jefferson County swap meet and a couple of those parts were 1992 Spindles to match the 1992 possi rear end in the back of the car.

So I purchased all components matching a 1992 and I adapted the original brackets on the body to work with these new Russel stainless steel brake lines. Below I will show how and what I used.

There are people out there that believe you should swap all components, but really there is no need. I reviewed Part numbers for the 1979 V8 master cylinder and 4 cylinder master cylinder and the replacement parts are the exact same. That is also the case for the brake booster. Don't waste your money if you don't have too. I like to use to compare things with their site's database feel, it made it very easy to compare.

Picture below to the left is a CarQuest Part number for the adapter you will need. I also thought it would be nice to share the knowledge that Advance Auto bought out CarQuest. The picture to the right is how the original 1979 Ford Caliper Line appears. I searched the salvage yards for a replacement and every mustang I came across had the mount rusted gone, so I decided to modify my original. Take great care when doing this. 

Here I took the "C" clip off of the line so that I can insert and trace material needing to be removed.

After the clip is removed insert and scratch an outline on the bracket.

Below I used an air file that I bought from Harbor Freight a few years back. Take it slow this file makes things go quick. Take your time do multiple tests fits. Removing material is much easier then adding. 

Below to the right you see finished product and it fits like it was from factory. Holds the line snug and secure with no play as it should be.

Adapters installed and line secure. 

This is the clearance from the strut to 17x9 wheels.
