10% FOR OLD BRAKES, 20% FOR NEW BRAKES
The rule of thumb for determining the best stop time limit is to add 20% to the stopping time
of your press if your brakes are new. Add 10% if your brakes are old.
Here is the reasoning behind this rule. Stopping time should be less with a new brake. So
when the 20% is added to stopping time, the number should be approximately the same as
the number you get when you add 10% to stopping time for an older brake.
Examples for calculating the stop time limit
Example 1: Your recorded stopping time is 207 ms and your brake is old:
Take 10% of 207:
Add 21 to 207 207 + 21 = 228
228 ms is the calculated stop time limit.
Example 2: Your recorded stopping time is 175 ms and your brake is new:
Take 20% of 175:
Add 35 to 175 175 + 35 = 210
210 ms is the calculated stop time limit.
