Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Disconnect the 12V battery to prevent electrical issues.

2. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the wheel using a socket set.
2. Check the thickness of the brake pads; replace if worn below 3mm.
3. Remove the caliper bolts with a ratchet and socket, and detach the caliper.
4. Replace the old pads with new ones, ensuring proper orientation.
5. Reattach the caliper and torque bolts to manufacturer's specifications (typically around 25-30 Nm).

3. Inspect and Resurface/Replace Brake Rotors

Sub-steps:
1. If the rotors are warped, measure runout using a dial gauge.
2. If out of specification, either resurface the rotors or replace them.
3. To replace, remove the rotor from the hub by removing retaining screws or bolts.
4. Install new or resurfaced rotors and secure them with retaining screws/bolts.

4. Check Brake Calipers

Sub-steps:
1. Inspect caliper pistons for movement; ensure they retract smoothly.
2. Clean any debris or rust from the calipers and lubricate sliding pins.
3. Check for fluid leaks; replace any faulty calipers as necessary.

5. Brake Fluid Check and Replacement

Sub-steps:
1. Open the brake fluid reservoir and inspect fluid level and condition (should be clear).
2. If contaminated, perform a brake fluid flush.
3. Use a brake bleeder kit to remove old fluid and replace with new DOT 3 or DOT 4 fluid.

6. Reassemble and Test

Sub-steps:
1. Reinstall the wheel and torque lug nuts to specifications (typically 100-120 Nm).
2. Reconnect the battery and ensure all components are functioning properly.
3. Perform a test drive to confirm the vibrations are resolved.

Tools Required:

Socket set
Torque wrench
Brake bleeder kit
Dial gauge (for rotor measurement)

Parts Required:

Brake pads
Brake rotors (if warped)
Brake fluid (DOT 3 or DOT 4)

Estimated Repair Time: 2-4 hours

Safety Warnings:

Always wear safety glasses and gloves when working on brake components.
Allow the vehicle to cool before working on the braking system.
