⚠️ Safety Warnings

Important safety information - read before proceeding

•Always ensure the vehicle is securely lifted and supported before working underneath.
•Allow the brakes to cool before starting any work, as they can become very hot from use.

Symptoms

•Squeaking or grinding noises when braking
•Increased stopping distance
•Brake pedal feels spongy or soft
•Vibration or pulsation in the brake pedal
•Warning light illuminated on the dashboard
•Brake fluid level is low

Diagnostic Steps

1
Inspect the brake pads visually for wear; look for less than 3mm of pad thickness.
2
Test drive the vehicle and assess for unusual noises or reduced braking performance.
3
Check the brake fluid level in the reservoir; if low, inspect for leaks.
4
Use a multimeter to check the brake sensor if the warning light is illuminated.
5
Inspect the rotors for warping or scoring.

Solution

Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety goggles and gloves.

2. Remove Wheel

Loosen lug nuts using a socket wrench before lifting the vehicle.
Use a jack to lift the vehicle and place jack stands for safety.
Remove the lug nuts and take off the wheel.

3. Remove Brake Caliper

Use a socket wrench to remove the caliper bolts.
Carefully slide the caliper off the brake pads and support it with a bungee cord to avoid straining the brake line.

4. Inspect and Replace Brake Pads

Check the brake pads for wear; if they are less than 3mm thick, replace them.
Remove the old pads and install the new ones, ensuring they are properly seated in the caliper bracket.
If necessary, use a brake caliper tool to compress the caliper piston to fit over the new pads.

5. Reassemble Components

Reattach the brake caliper and torque the bolts to the manufacturer’s specifications (usually around 25-30 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts before lowering the vehicle.

6. Finalize and Test

Lower the vehicle and torque the lug nuts to the manufacturer’s specifications (typically 80-100 ft-lbs).
Pump the brake pedal several times to ensure proper pad seating.
Check the brake fluid level and add if necessary.
