Master Cylinder Bore Too Big at Faith Marquis blog

Master Cylinder Bore Too Big. When the pedal force is increased or the pedal ratio is increased (or perhaps both at once), the stroke of the master cylinder is shortened (brake line pressure is unaffected). View the conversion chart to figure the total bore area for your brake setup. I replaced a 1.25 bore master. Master cylinder bore is too big and you honestly could use some more pedal ratio. When the master cylinder piston size is increased, the output pressure of the master cylinder is decreased. By increasing the bore diameter of the master you have reduced the actual pressure that can be applied by the pistons and slave cylinders but reduced the travel of the pedal. Brakes work best when the brake pedal force, master cylinder size, and brake caliper size are in harmony. In every and all cases, changing to a smaller master cylinder bore size will increase line pressure at the expense of longer pedal travel. We see a lot of confusion about master cylinder sizing and how it impacts pedal feel and clamping force. Closer to 7:1 will make a difference. Everything in my brake system is new. The answer lies in the balance of the braking system.
