After rebuilding a master cylinder, what adjustment should be made to the connecting rod?

After rebuilding a master cylinder, adjusting the connecting rod properly is essential to ensure that the brake system functions efficiently. The connecting rod links the brake pedal to the master cylinder, and if it is not adjusted correctly, it can lead to insufficient or excessive free play in the brake pedal.

When the connecting rod is adequately adjusted, it allows for the correct amount of travel in the master cylinder piston, ensuring that the brake fluid is adequately displaced to apply the brakes effectively. Proper adjustment helps achieve the right balance of pedal feel and responsiveness, contributing to the vehicle's safety and control.

If the connecting rod is left unadjusted, it could lead to operational issues such as hard or soft brake pedal feel, affecting overall braking performance. Therefore, making the appropriate adjustments is crucial for the functionality and safety of the braking system.
