Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Always disconnect the battery when working on brake systems.
•Allow brakes to cool before servicing to avoid burns.

Symptoms

•Squeaking or grinding noise when brakes are applied
•Reduced braking efficiency or longer stopping distance
•Brake warning light illuminated on the dashboard
•Vibration or pulsation felt through the brake pedal
•Brake fluid leak near the rear wheels
•Uneven wear on rear brake pads

Diagnostic Steps

1
Inspect rear brake pads for wear and thickness using a brake pad gauge.
2
Check brake rotors for scoring or warping by measuring with a micrometer.
3
Examine brake calipers for proper function and any signs of hydraulic fluid leakage.
4
Inspect brake lines for damage or wear that could cause fluid leaks.
5
Test brake fluid level and condition in the master cylinder reservoir.
6
Check for any error codes using an OBD-II scanner if the brake warning light is illuminated.

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 all necessary tools and parts.
Ensure the vehicle is parked on a level surface and securely raise the rear of the vehicle using jack stands.
Remove the rear wheels using a lug wrench.

2. Remove Brake Components

Brake Caliper Removal:
- Use a socket set to remove the caliper bolts (typically 12mm or 14mm).
- Gently slide the caliper off the rotor and support it using a bungee cord or rope to avoid strain on the brake line.
Brake Pad Removal:
- Remove the old brake pads from the caliper bracket. Note their orientation for installation of new pads.

3. Inspect and Replace Components

Inspect Rotors:
- Measure rotor thickness with a micrometer. Replace if below minimum specifications (usually 1mm over the discard thickness).
- If rotors are warped or scored, remove them by unbolting the rotor from the hub.
Clean Components:
- Clean the caliper bracket and rotor surfaces using brake cleaner and a wire brush.

4. Install New Brake Pads and Components

Install New Brake Pads:
- Apply brake grease to the backing of the new pads (avoid contact with the friction material).
- Position the new pads into the caliper bracket as per the original orientation.
Reinstall Caliper:
- Compress the caliper piston using a caliper tool or C-clamp to fit over the new pads.
- Slide the caliper back over the pads and secure it with the caliper bolts. Torque to specifications (usually around 20-30 ft-lbs).

5. Final Assembly

Reinstall the rear wheels and hand-tighten the lug nuts.
Lower the vehicle back to the ground and apply the brakes a few times to seat the pads properly.
Torque the lug nuts to the manufacturer's specification (typically 80-100 ft-lbs).
