Diagnostic Steps

1
Inspect brake pads for uneven wear and thickness.
2
Check brake rotors for warping or scoring using a dial indicator or straight edge.
3
Examine brake calipers for proper operation and any signs of sticking or binding.
4
Verify wheel alignment and balance.
5

Solution

1. Preparation

Gather required tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Use wheel chocks to prevent movement.

2. Remove Wheel

Loosen lug nuts using a socket wrench.
Lift the vehicle with a jack and secure it on jack stands.
Remove the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Remove the caliper by unscrewing the caliper bolts.
Carefully slide the caliper off the rotor and support it without straining the brake line.
Inspect the brake pads for wear; replace if necessary.
- Tools Required: Socket set, pad spreader
- Safety Warning: Ensure brake fluid reservoir cap is removed prior to compressing caliper pistons.

4. Inspect and Replace Brake Rotors

Remove the rotor if warped or damaged.
Use a dial indicator to measure rotor thickness and ensure it meets specifications.
Install new rotors if necessary, ensuring they are clean and free of oil.
- Torque Specification: Tighten rotor screws to manufacturer’s specifications.

5. Reassemble and Test

Reinstall the caliper with new pads or after cleaning existing pads.
Reattach the wheel and hand-tighten lug nuts before lowering the vehicle.
Lower the vehicle and fully tighten the lug nuts to the specified torque value.
Test brake operation before driving.
