Be sure to install spring assembly correctly, with
larger ball socket end pointing to the pedal struc-
ture and smaller end toward the valve assembly.
NOTE: If pedal is adjusted properly, the spring assem-
bly will not interfere with pedal travel.
The spring and spring pivots are different for ped-
als equipped with and without the electric retard
pedal mounted to the brake pedal. DO NOT inter-
change the springs or spring pivots.
