How do you visually inspect brake rotors?
If you have an open-spoke wheel design, you can run your finger vertically down the brake rotor friction surface. If you can feel and see noticeable grooves, then it’s time for new brake rotors.

- Move the mark to 0mm on your ruler and take your final measurement.
- If your brake pads are 4mm and less, consider replacing them.
How do I know if my bike disc brakes need replacing?
Disc brake pads should be replaced before they are worn this thin. Braking erodes material off the rotor depending on the riding conditions, rotors will typically last through two or more sets of brake pads. When a SHIMANO rotor measures 1.5mm thick or less, it’s time to replace it.

Do disc brakes have brake adjustment issues?
And ‘brake adjustment’ just isn’t an issue with disc brakes.” On a drum brake, braking force decreases as brake stroke increases. With disc brakes, pushrod travel shortens as the rotor gets hot and expands. Brake performance actually improves as brakes get hotter.
