(A) This is the brake cylinder overstroke limit switch (overstroke switch). The overstroke switch is normally closed. The overstroke switch opens when the pistons in the master cylinder travel too far. A brake overstroke condition can result from low brake fluid level, air in the brake hydraulic circuit, leakage in the brake hydraulic lines, and master cylinder piston seal leaks. An indicator will come on in the cab and the alarm will sound. Do not operate the machine until the cause for the overstroke has been corrected.
(B) This is the brake air pressure switch. The brake air pressure switch monitors brake air pressure. The operator will be alerted to a condition of low air pressure.
(C) This is the pressure switch for the Traction Control System (TCS). This
