⚠️ Safety Warnings

Important safety information - read before proceeding

•Always wear safety goggles and gloves when working on brakes.
•Ensure the vehicle is secure before working underneath it.

Symptoms

•Squeaking or squealing noise when braking
•Grinding noise when brakes are applied
•Vibration or pulsation in the brake pedal
•Longer stopping distances than usual
•Brake warning light illuminated on the dashboard
•Brake fluid leak near the wheels

Diagnostic Steps

1
Inspect brake pads visually for thickness; if they are less than 1/4 inch, they likely need replacement.
2
Listen for unusual sounds when braking; squeaking or grinding indicates worn pads.
3
Check for any abnormal vibration or pulsation in the brake pedal during braking.
4
Examine brake fluid levels in the reservoir; low fluid may suggest a leak or worn pads.
5
Inspect brake rotors for scoring, warping, or excessive wear.

Solution

Solution

1. Preparation

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

2. Lift the Vehicle

Use a jack to elevate the vehicle and secure it with jack stands.
Ensure the vehicle is stable before proceeding.

3. Remove the Wheel

Use a lug wrench to loosen and remove the wheel lug nuts.
Take off the wheel to access the brake components.

4. Inspect and Remove Brake Components

Inspect the brake pads and rotors visually.
If replacement is needed, remove the caliper by unscrewing the caliper bolts using a socket wrench.
Slide the caliper off the rotor and support it with a bungee cord or rope to avoid stressing the brake line.

5. Replace Brake Pads and Rotors (if necessary)

Remove the old brake pads from the caliper bracket.
If the rotors are worn, remove them by unscrewing any retaining screws and sliding them off the hub.
Install new rotors (if applicable) and secure them in place.
Insert new brake pads into the caliper bracket, ensuring they are properly aligned.

6. Reassemble Components

Reposition the caliper over the new brake pads and rotor.
Tighten the caliper bolts to the manufacturer’s specifications (generally around 25-30 ft-lbs).
Reinstall the wheel and tighten the lug nuts in a crisscross pattern to the specified torque (typically 75-80 ft-lbs).

7. Lower the Vehicle

Carefully remove the jack stands and lower the vehicle back to the ground.

8. Final Check

Pump the brake pedal several times to ensure proper brake pad seating and restore brake pressure.
Check brake fluid level and top off if necessary.
