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\/p\u003e\n\u003cp\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\/p\u003e\n\u003cp\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\/p\u003e\n\u003cp\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\/p\u003e\n\u003cp\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.  That ratio is right where we want to be. 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 is 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).\u003c\/p\u003e\n\u003cp align=\"center\"\u003e\u003cimg class=\"__mce_add_custom__\" title=\"pedalratio.jpg\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0675\/3307\/8705\/files\/pedalratio_8fc2a4a2-1633-4224-86f5-42cf73924a9f.jpg?v=1738182500\" alt=\"pedalratio.jpg\" width=\"205\" height=\"205\"\u003e \u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"UPR","offers":[{"title":"Default Title","offer_id":46807803297941,"sku":"UPR-3008-03","price":169.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0571\/1839\/2469\/files\/05-11-ford-mustang-strange-manual-brake-kit-3__35977.1511302052.1280.1280.jpg?v=1767668151","url":"https:\/\/blowbyracing.com\/products\/upr-2005-2011-manual-brake-kit-1-125-mc-strange","provider":"Blow-By Racing","version":"1.0","type":"link"}
