Most people prefer power-assisted brakes over manual brakes, making a Hydroboost conversion the best solution.\u003c\/div\u003e\n\u003cdiv\u003eExcellent brake response regardless of engine vacuum. Vacuum-assisted brakes provide varying levels of assist, depending upon the available vacuum supply. The changing assist causes inconsistent pedal feel. This is especially noticeable in a Mustang that's open-tracked, due to the wide fluctuations in vacuum from extended periods of wide-open throttle followed by hard braking zones.\u003c\/div\u003e\n\u003cdiv\u003eNot enough vacuum at idle to operate a vacuum booster. Some pushrod engine cams don't allow the engine to create enough vacuum to operate a vacuum brake booster.\u003c\/div\u003e\n\u003cdiv\u003eLow brake pedal effort, even with small-diameter brake rotors.\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cstrong\u003eWhat's included?\u003c\/strong\u003e\u003c\/div\u003e\n\u003cdiv\u003eFirewall adapter block.

The 4 mounting studs are located to match the Fox firewall pattern of holes.\u003c\/div\u003e\n\u003cdiv\u003eBrake pedal. The pedal arm is made of high-strength alloy steel, with the pushrod pin in the correct location to match the brake pedal ratio and pushrod geometry of a 1999-2004 Hydroboost Mustang.

The separate pedal pad is adjustable via multiple mounting holes to accommodate different driver preferences.\u003c\/div\u003e\n\u003cdiv\u003ePedal box spacer.

It will work with most of the front and rear caliper setups used on SN95 and Fox Mustangs. A limitation is the lack of master cylinder sizes available for the Hydroboost. This makes it important to confirm that the volume of fluid required to move the caliper pistons is compatible with the volume of fluid the master cylinder can deliver. If the caliper piston requirement is excessive, the brake pedal will have an overly long stroke, which is very disconcerting for the driver. At the extreme, if it exceeds what the master cylinder can deliver, the piston in the master cylinder will reach the end of its stroke and bottom out, preventing full application of the brakes.\u003c\/div\u003e\n\u003cdiv\u003eWhile you're confirming that your Mustang's calipers are a match to the Hydroboost master cylinder, it's also a good time to confirm your Mustang's front to rear brake bias is in the range of what works well. Fox and SN95 Mustang brakes should have between 70% and 75% front bias (also referred to as 70\/30 and 75\/25). The more heavily modified the suspension is for improved handling, the closer to 70% the front bias should be. An exception is a street and\/or strip Mustang running an extreme 'big-and-little' combination of fat rear tires and skinny frontrunners, where substantially more rear bias is required to offset the lack of front tire grip.\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cstrong\u003eHow do I confirm my brake calipers are a match to the Hydroboost master cylinder, and that my bias is good?\u003c\/strong\u003e\u003c\/div\u003e\n\u003cdiv\u003eYou can calculate the fluid requirement of your calipers from the piston area, and then segue into calculating the bias by taking into account the rotor diameters.

Select the Fox Hydroboost Conversion option, and follow the instructions.\u003c\/div\u003e\n\u003cdiv\u003eMost of the aftermarket big brake kits listed for SN95 Mustangs also work well on a Fox Mustang.

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.\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003eIf 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.\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003eBrake 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.\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003eThe UPR Manual Brake Kits use commonly available high-quality Strange Engineering 1.125 inch bore master cylinders which is a good fit for most Mustang disc brake systems. A good ballpark pedal ratio to shoot for with this size master cylinder is 6 or 6 1\/2 to 1. Driver preference can determine if you want more or less leverage.\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003eTo 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 now we’re right where we want to be. Mark the location, and that will be where you will weld the stud or drill and install a Grade 8 bolt to connect your brake push rod.\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv\u003eThe UPR Billet Mustang Manual Brake Adapter Plates are machined to a common angle.
