What should be inspected when checking the brake pads?

When checking the brake pads, you should inspect the following:
- Brake pads should have at least 1/4 of an inch of thickness remaining. If the brake pads are worn thinner than 1/4 of an inch, they should be replaced immediately.
- Brake pads should be free of cracks and breaks. Any cracks or breaks in the brake pads can weaken them and make them more likely to fail.
- The brake pads on the inner and outer wheels should wear evenly. If the brake pads are worn unevenly, it could be a sign of a problem with the braking system.
- The brake calipers and rotors should be free of leaks and damage. Any leaks or damage to the brake calipers or rotors could affect the performance of the braking system.
