Organic acids are of two types. One has the COOH group (the carboxyl group). An example is acetic acid (CH3COOH), the acid in vinegar. It is made by oxidizing grain alcohol or by the fermentation of the fruit sugar in cider. The other type has a phenol group, as in phenol (C6H5OH).
Calculate the total braking distance. This formula is 1/2 the initial velocity in feet per second multiplied by the time required to stop, which is 0.5 x 102.7 x 5.135 = 263.68. The calculated thinking distance is 2 x 102.7 = 205.4. Add the two numbers together. 469.08 feet is the total braking distance.
Brake rotors should be measured at every brake pad replacement. If found to be at or below the manufacturer's minimum thickness specification, they will require replacement. These measurements should always be noted on your repair order. We recommend braking gently for the first 40 to 50 miles of driving on new pads.rake rotors should be measured at every brake pad replacement.
