Diagnostic Steps

1
Inspect brake pads for wear and tear using a visual inspection.
2
Check brake rotors for scoring or warping.
3
Examine brake calipers for proper operation and any signs of sticking.
4
Test brake fluid level and condition.
5
Scan the vehicle's onboard diagnostics for any fault codes related to the braking system.

Solution

1. Preparation

Park the vehicle on a level surface and engage the parking brake.
Gather necessary tools and parts.
Ensure the vehicle is in "Service Mode" if applicable.

2. Inspect Brake Pads

Tools Required: Torque wrench, socket set
Remove the wheel using a socket set.
Inspect the brake pads for thickness; if they are less than 3mm, they should be replaced.
Check for any uneven wear patterns or cracking.

3. Inspect Brake Rotors

Remove caliper bolts with a socket set and carefully lift the caliper off the rotor.
Inspect the rotors for scoring or warping; replace if damaged.
Clean the rotor surface with brake cleaner to remove any debris.

4. Check Brake Calipers

Verify that the calipers are free-moving; if they appear to be sticking, they may need to be serviced or replaced.
Lubricate the caliper slide pins with high-temperature brake grease.

5. Replace Brake Components (if necessary)

If brake pads or rotors are worn, replace them with OEM or high-quality aftermarket parts.
Reassemble the brake components by reversing the disassembly steps.
Torque caliper bolts to manufacturer specifications (typically 25-35 ft-lbs).
