A professional mechanic will typically perform a thorough inspection of the brake pads, rotors, calipers, brake lines, and other components of the braking system to identify any signs of wear or damage
If the brake pads are worn down or damaged, the mechanic may recommend replacing them with new pads
If the rotors are warped, damaged, or worn beyond their specifications, the mechanic may recommend resurfacing the rotors or replacing them with new ones.
If the calipers are stuck, seized, or leaking brake fluid, the mechanic may recommend repairing or replacing them
If the brake fluid is old, contaminated, or low, the mechanic may recommend flushing the brake fluid and replacing it with fresh fluid
If the brake lines are leaking, corroded, or damaged, the mechanic may recommend repairing or replacing them
Brake fluid can become contaminated over time, which can cause the brakes to feel spongy or less responsive.
