The most common question that is asked of our Technical Representatives is why do I have a hard brake pedal. Right behind that in frequency is the direct opposite question of why do I have a soft brake pedal and what might be causing it. This question is usually a little easier to answer but the answers can often be forgotten and might need a little reminder.
Whether your vehicle has power or manual brakes, pedal ratio is important. If you are experiencing a hard pedal you should check your pedal ratio if you have converted from the vehicle’s OE set up. As a general rule, your pedal ratio should not exceed 6:1 for manual brakes with a 1” bore master cylinder and 4:1 for power brakes with a 1-1/8” bore master.
