shows the linkage with the brake pedal at rest. Note the slot in the clevis above the pivot pin. As the brake pedal is pressed Notice above just how much free-play is built into the rear brake before you can use the brake at all! The image on the right downward, this space is taken up until the pivot pin contacts the top of the clevis as shown in the right frame. This little bit of movement translates into 1-1/2in. of movement at the pedal!
This close-up of the clevis shows the amount of free-play in the rear brake linkage. Tighten this up and the brake will be actuated without all that free-travel.
