•Uneven brake wear on pads
•Grinding or squeaking noise when braking
•Vehicle pulls to one side during braking
•Brake fluid leaking around caliper
•Warning light illuminated on the dashboard

Diagnostic Steps

1
Visual Inspection: Check calipers, pads, and rotors for signs of wear or damage.
2
Brake Fluid Level Check: Inspect the brake fluid reservoir for proper fluid level.
3
Brake Pad Thickness Measurement: Measure the thickness of the brake pads to determine if they are within specification.
4
Caliper Function Test: Apply the brakes and observe caliper movement for proper operation.
5
Inspect Brake Lines: Look for any leaks or damage in the brake lines connected to the caliper.
6
Scan for Error Codes: Use an OBD-II scanner to check for any related error codes that may indicate braking system issues.

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and secure with wheel chocks.
Disconnect the battery to prevent electrical issues.

2. Remove Wheel

Sub-steps:
- Loosen lug nuts using a lug wrench.
- Lift the vehicle using a jack and secure with jack stands.
- Remove the wheel to access the brake caliper.

3. Remove the Caliper

Sub-steps:
- Remove caliper mounting bolts using a socket set.
- Carefully slide the caliper off the rotor.
- Suspend the caliper using a bungee cord or suitable method to avoid straining the brake line.

4. Inspect and Clean

Sub-steps:
- Inspect the caliper for cracks, corrosion, or any damage.
- Clean the caliper and mounting surfaces using brake cleaner and a brush.
- Check the piston for smooth operation; it should move freely without sticking.

5. Replace Components (if necessary)

Sub-steps:
- If pads are worn, remove the old pads and replace with new ones.
- If the caliper is damaged, replace it with a new or rebuilt unit.
- Reinstall caliper and torque mounting bolts to manufacturer specifications (typically around 20-30 ft-lbs).

6. Reassemble and Test

Sub-steps:
- Reinstall the wheel and torque lug nuts to specifications (typically 100-130 ft-lbs).
- Lower the vehicle and reconnect the battery.
- Pump the brake pedal to seat the pads against the rotor.
- Test drive the vehicle at low speeds to ensure proper brake function.
