⚠️ Safety Warnings

Important safety information - read before proceeding

•Always wear safety goggles and gloves when working on brakes.
•Ensure the vehicle is securely lifted and supported before working underneath.

Symptoms

•Squeaking or squealing noise when braking
•Grinding noise when braking
•Reduced braking performance or longer stopping distances
•Vibration or pulsation in the brake pedal
•Warning light on the dashboard (if equipped)
•Brake pads appear visibly worn or thin upon inspection

Diagnostic Steps

1
Inspect the brake pads visually through the wheel spokes to check for thickness. Pads should be at least 1/4 inch thick.
2
Listen for any unusual noises such as squeaking or grinding when applying the brakes.
3
Conduct a brake performance test to assess stopping distances and effectiveness.
4
Check for vibrations in the brake pedal during braking, indicating potential pad wear or rotor issues.
5
Look for any warning lights on the dashboard related to the brake system.
6
Inspect the brake fluid level in the reservoir; low fluid can indicate worn pads.

Solution

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the parking brake engaged.
Wear safety gloves and goggles.

2. Lift the Vehicle

Use a jack to lift the vehicle and secure it on jack stands.
Remove the wheel using a lug wrench.

3. Remove Brake Caliper

Use a socket set to remove the caliper bolts.
Carefully slide the caliper off the brake rotor and support it using a bungee cord or rope to avoid stressing the brake line.

4. Inspect and Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Inspect the brake pad backing plates for wear and the condition of the shims.
Install new brake pads into the caliper bracket, ensuring they are oriented correctly.
Apply a thin layer of brake grease on the back of the pads to reduce noise.

5. Reassemble Brake Components

Reposition the caliper over the new pads and rotor.
Reinstall the caliper bolts and tighten them to the manufacturer’s torque specifications (typically around 20-25 ft-lbs for Toyota).
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower the Vehicle

Carefully lower the vehicle from the jack stands using a jack.
Tighten the lug nuts to the specified torque (usually 76 ft-lbs for Corolla).

7. Test Brakes

Pump the brake pedal a few times to seat the pads against the rotor.
Perform a test drive to ensure proper braking performance.
