Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Always disconnect the battery before working on the braking system.
•Allow the brakes to cool before inspecting to avoid burns.

Symptoms

•Uneven brake wear on pads
•Squeaking or grinding noise when braking
•Vehicle pulls to one side during braking
•Brake fluid leaks around the caliper
•Reduced braking performance or pedal feel
•Overheating of the wheel or brake components

Diagnostic Steps

1
Inspect brake fluid level in the reservoir; ensure it is within the recommended range.
2
Visually inspect the brake calipers for any signs of fluid leaks or corrosion.
3
Check the condition of the brake pads for uneven wear or damage.
4
Test the brake pedal feel; assess if it feels spongy or if it sinks to the floor.
5
Perform a visual inspection of the brake rotor for scoring or discoloration.
6
Check for caliper movement by pushing the brake pedal and observing caliper operation.

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 necessary tools and parts.
Ensure the vehicle is parked on a flat surface and securely raise it using jack stands.
Wear safety gloves and goggles.

2. Inspect and Remove Caliper

Sub-steps:
1. Remove the wheel using a lug wrench.
2. Locate the caliper bolts and remove them using a socket wrench.
3. Carefully slide the caliper off the rotor; support it using a bungee cord or similar to avoid stress on the brake line.

3. Examine Brake Pads and Rotors

Sub-steps:
1. Remove the brake pads from the caliper bracket.
2. Inspect the pads for uneven wear; measure thickness to ensure they are above the minimum specification.
3. Check the brake rotor for any signs of warping or excessive wear. If necessary, use a micrometer to measure rotor thickness.

4. Check Caliper Functionality

Sub-steps:
1. With the caliper removed, inspect the piston for corrosion or damage; ensure it moves smoothly when pushed in.
2. If the piston is stuck, use a caliper tool to gently compress it back into the caliper housing.
3. Clean the caliper slides and lubricate with high-temperature brake grease.

5. Reassemble

Sub-steps:
1. Reinstall the brake pads into the caliper bracket.
2. Slide the caliper back onto the rotor and secure it with the caliper bolts; torque to the manufacturer’s specifications (typically around 20-30 ft-lbs).
3. Reinstall the wheel and lower the vehicle to the ground.
