⚠️ Safety Warnings

Important safety information - read before proceeding

•Always wear safety goggles and gloves when working on brakes.
•Allow the vehicle to cool down before working on brake components to avoid burns.

Symptoms

•Squeaking or squealing noise when brakes are applied
•Grinding noise indicating metal-on-metal contact
•Reduced braking performance or longer stopping distances
•Vibration or pulsation in the brake pedal while braking
•Warning light illuminated on the dashboard (if equipped)
•Brake fluid level lower than normal

Diagnostic Steps

1
Inspect the brake pads visually through the wheel spokes to check thickness.
2
Listen for unusual noises when applying the brakes during a test drive.
3
Check for any warning lights on the dashboard indicating brake issues.
4
Measure brake pad thickness using a caliper; pads should be at least 3mm.
5
Inspect the brake rotors for scoring or damage while checking the pads.
6
Feel for vibrations in the brake pedal during braking.

Solution

Solution

1. Preparation

Gather tools and parts needed for brake pad replacement.
Ensure the vehicle is parked on a flat surface and the engine is off.
Lift the vehicle using a jack and secure with jack stands.

2. Remove Wheel

Using a lug wrench, loosen and remove the lug nuts from the wheel.
Carefully remove the wheel to access the brake assembly.

3. Remove Old Brake Pads

Locate the caliper and remove the bolts holding it in place using a socket set.
Carefully slide the caliper off the brake rotor; support it with a bungee cord to avoid strain on the brake line.
Remove the old brake pads from the caliper bracket.

4. Install New Brake Pads

Apply a thin layer of brake grease to the back of the new brake pads to prevent squeaking.
Position the new brake pads into the caliper bracket, ensuring they are seated properly.

5. Reassemble Braking System

Retract the caliper piston using a brake caliper tool to allow space for the new pads.
Reinstall the caliper over the new brake pads and secure it with the caliper bolts, tightening to manufacturer specifications (typically around 20-30 ft-lbs).
Reattach the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Test

Lower the vehicle back to the ground and use a torque wrench to tighten the lug nuts to the proper specification (usually around 80-100 ft-lbs).
Pump the brake pedal several times to ensure proper pad seating.
Test drive the vehicle to ensure proper braking function.
