Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Always ensure the vehicle is securely supported on jack stands before working underneath.
•Allow brake components to cool before handling to avoid burns.

Symptoms

•Brake pedal feels soft or spongy
•Uneven brake wear on front or rear brake pads
•Vehicle pulls to one side during braking
•Brake fluid leaks around the caliper
•High-pitched squealing noise when brakes are applied
•Burning smell from the wheels after driving

Diagnostic Steps

1
Inspect brake fluid level in the master cylinder reservoir.
2
Visually check for fluid leaks around the caliper and brake lines.
3
Perform a wheel rotation to access the brake components.
4
Check the condition of the brake pads and rotors for wear or scoring.
5
Test the caliper operation by physically pushing the caliper piston back.
6
Monitor for any uneven temperature on the wheel after a test drive.

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

Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, brake cleaner, and safety glasses.
Raise the vehicle using a jack and secure it with jack stands.
Remove the wheel using a lug wrench.

2. Inspect Caliper and Brake Pads

Sub-steps:
1. Clean the caliper and surrounding area with brake cleaner to remove dust and debris.
2. Inspect the caliper for any visible cracks or damage.
3. Check the brake pads for uneven wear; replace if significantly worn.
4. Examine the rotor surface for any scoring or warping.

3. Test Caliper Function

Sub-steps:
1. Using a C-clamp or brake caliper tool, gently push the caliper piston back into the housing.
2. Observe if the piston retracts smoothly; resistance may indicate a bad caliper.
3. Reconnect the brake line if it was disconnected for inspection.

4. Replace Caliper (if necessary)

Sub-steps:
1. If a caliper replacement is needed, detach the brake line from the caliper using a wrench.
2. Unbolt the caliper from the bracket using a socket set.
3. Install the new caliper by reversing the removal steps, ensuring to torque bolts to manufacturer specifications (typically 25-35 ft-lbs).
4. Bleed the brake system to remove any air by using a brake bleeder or having an assistant pump the brake pedal.

5. Reassemble and Test

Sub-steps:
1. Reattach the wheel and lower the vehicle.
2. Test the brake pedal feel before driving.
3. Conduct a short test drive to evaluate braking performance.
