Description
Get a jump start on converting your race 94-04 Mustang to a manual brake setup to save weight and space over the factory brake booster system. Includes a custom Billet Mounting plate with studs for the firewall and master, Strange 1.125 dual inline master cylinder with lines exiting towards the fender and custom adjustable brake rod. Will require making new lines from master cylinder to existing brake lines. Does not bolt up directly to factory lines.
1.03" bore master cylinder is typically used in cars with stock drums and factory disc brakes up front. 1.125" bore master cylinder would be used in applications with disc brakes on all four corners, especially when using aftermarket brakes.

Brake Pedal Ratio
When converting your Power Brake System to a Manual Brake System, the first thing you need to consider is that you are removing the ‘Power’ from the brake system. In other words, there will be no more power assist, and you will have to rely on good old mechanical leverage to get the car stopped properly.
If you just install your UPR Manual Brake kit and hook it up without modifying the factory Power Brake Pedal, you will not physically be able to apply enough muscle to the pedal to get the car to stop like it should. Why? Brake Pedal Ratio.
Brake Pedal Ratio is the relationship between the brake pedal pivot point at the pedal mount, the brake pedal push rod location, and the brake pedal pad itself which makes up the leverage to produce pressure in the braking system. The power assist brake pedal would use a lower ratio since not as much leverage is required to achieve the correct brake system pressure (usually about 1200psi at the front caliper). When switching to manual, you will want more mechanical leverage to compensate for the loss of power assist. It’s the same principle as using a long breaker bar to loosen a stubborn bolt.
The UPR Manual Brake Kits use commonly available high-quality Strange Engineering 1.125 inch bore or 1.032 inch bore master cylinders which is a good fit for most Mustang disc brake systems. A good ballpark pedal ratio to shoot for with the 1.125 in master cylinder is 6 or 6 1/2 to 1, while Strange Engineering recommends a 5.5 to 1 ratio for the 1.032 master. Driver preference can determine if you want more or less leverage.
To determine your pedal ratio, start by measuring from the pivot point, (where the pedal assembly attaches to the body or frame) to the center of the brake pedal pad (A). Next, measure from the pivot point to the master cylinder push rod connection (B). Divide the first measurement (A) from the second (B) and the result is your pedal ratio. You will modify the pedal to get the desired ratio by moving the pushrod mounting point (generally going up). For example, let’s say the power brake pedal measures 13 inches from the center of the pivot to the center of the pedal pad, and the pushrod mount is 3 inches from the pivot 13÷3= 4.33 so we’ll say a 4 to one ratio. Not good for a manual set up. If we do some quick math to see what moving the hole up an inch will do, 13÷2= 6.5. That ratio is right where we want to be for a 1.125 in Master. Mark the location, mock up your brake pushrod, to make sure the angle will work, and that will be where you will weld the stud or drill and install a Grade 8 bolt to connect your brake push rod. If the angle to too great, you may need to lower the stud location slightly (going up 7/8 of an inch instead of one inch would still be 6.1:1).
The UPR Billet Mustang Manual Brake Adapter Plates are machined to a common angle. You may need to add shims or washers behind the plate to achieve the desired pushrod angle for your application.
The UPR Manual Brake Kit is a great way to start on your custom brake system. Custom brake lines and other components like proportioning valves and fittings will be necessary.
