Diagnostic Steps

1
Inspect brake pads for wear and tear using visual inspection.
2
Check brake rotors for warping or damage by measuring thickness and runout.
3
Examine wheel alignment and tire condition for uneven wear or damage.
4
Scan for any error codes using the vehicle's onboard diagnostics.
5

Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the negative terminal of the battery for electrical safety.

2. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the wheel to access brake components (use a jack and jack stands).
2. Remove the caliper bolts using a socket set.
3. Carefully slide the caliper off the rotor and support it without stressing the brake line.
4. Remove the old brake pads from the caliper bracket.
5. Install new brake pads, ensuring they are properly seated.
6. Reattach the caliper and torque bolts to manufacturer specifications.

3. Inspect and Resurface or Replace Brake Rotors

Sub-steps:
1. Check rotor thickness with a micrometer; replace if below specification.
2. If rotors are within specifications but warped, use a brake lathe to resurface them.
3. If replacing, remove the rotor by unscrewing the retaining screws.
4. Install the new or resurfaced rotor and secure it.

4. Check Wheel Alignment and Tire Condition

Sub-steps:
1. Inspect tires for uneven wear; replace if necessary.
2. Check tire pressure and adjust to manufacturer specifications.
3. If alignment is off, use alignment machine to adjust.

Tools Required:

Jack and jack stands
Socket set
Torque wrench
Micrometer or brake rotor gauge
Brake lathe (if resurfacing rotors)

Parts Required:

Brake pads (front and/or rear)
Brake rotors (if needed)
Tires (if needed)

Estimated Repair Time: 2-4 hours

Safety Warnings:

Disconnect the battery before working on electrical systems.
Ensure the vehicle is securely supported before working underneath it.
