Most common service
Pads wear down over time due to friction
Symptoms: squeaking, grinding, reduced stopping power
2. Rotor (Disc) Resurfacing or Replacement
Rotors can warp or wear unevenly
Resurfacing smooths the surface; replacement is required if it is too thin
Symptoms: vibration when braking
3. Brake Caliper Repair or Replacement
Calipers press pads against rotors
Can seize or leak over time
Symptoms: pulling to one side, uneven wear
4. Brake Fluid Flush & Replacement
Brake fluid absorbs moisture → reduces braking efficiency
Recommended every 2–3 years
Symptoms: soft or spongy brake pedal
5. Brake Line Inspection / Repair
