Affected Component

Brakes

Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect the battery before working on the braking system.
•Allow brakes to cool before inspection or replacement to avoid burns.

Symptoms

•Grinding noise when applying the brakes
•Increased stopping distance
•Vibration or pulsation in the brake pedal
•Brake warning light illuminated on the dashboard
•Reduced braking performance
•Possible burning smell from brakes after use

Diagnostic Steps

1
Inspect brake pads for wear: Remove the wheel and visually check the brake pads for thickness and uneven wear.
2
Check brake rotors: Measure rotor thickness and look for scoring or warping using a micrometer or caliper.
3
Examine brake calipers: Check for proper operation and ensure they are not sticking or leaking.
4
Inspect brake fluid: Check fluid level and condition in the reservoir, looking for contamination or low levels.
5
Listen for additional noises: With the vehicle stationary, have an assistant apply the brakes while you listen for grinding or other unusual sounds.

Solution

💡 Expert Tip

For complex repairs like this, consider taking photos at each step. This helps if you need to reverse a step or consult with a mechanic. Also, keep all removed parts organized - you may need to reference them during reassembly.

Verification

After completing the repair, verify that the issue has been resolved:

✓Test the affected component to ensure it functions correctly

Solution

1. Preparation

Gather tools and parts needed.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety during repairs.

2. Wheel Removal

Use a jack to lift the front or rear of the vehicle as necessary.
Secure the vehicle with jack stands.
Remove the wheel using a socket set.

3. Brake Pad Replacement

Remove Caliper:
- Use a socket set to remove the caliper mounting bolts.
- Carefully lift the caliper off the rotor and secure it with a bungee cord to avoid stressing the brake line.
Replace Brake Pads:
- Remove the old brake pads from the caliper bracket.
- Clean the caliper bracket with brake cleaner.
- Install new brake pads, ensuring they are properly seated.

4. Rotor Inspection and Replacement

Check Rotors:
- Measure the rotor thickness with a micrometer; replace if below manufacturer specifications.
- Inspect for scoring or warping; if damaged, remove the rotors by unscrewing the retaining screws or using a puller.
Install New Rotors:
- Clean new rotors with brake cleaner to remove protective oil.
- Install the new rotors and secure them according to manufacturer torque specifications.

5. Reassemble Brakes

Reattach the caliper over the new pads and rotor.
Tighten caliper bolts to the manufacturer’s torque specifications.
Reinstall the wheel and lower the vehicle.
