⚠️ Safety Warnings

Important safety information - read before proceeding

•Always wear safety glasses and gloves while performing brake work.
•Allow brakes to cool down after driving before working on them.

Symptoms

•Squeaking or squealing noise when brakes are applied
•Grinding sound that occurs during braking
•Vibration or pulsation felt through the brake pedal
•Reduced braking performance or longer stopping distances
•Warning light illuminated on the dashboard (if equipped)
•Brake pad wear indicator visible through the wheel spokes

Diagnostic Steps

1
Inspect the brake pads visually through the wheel spokes for thickness.
2
Listen for any unusual noises during braking, such as squealing or grinding.
3
Check the brake fluid level in the master cylinder reservoir.
4
Test the brake pedal feel; it should not feel spongy or sink to the floor.
5
Evaluate the overall performance during a short test drive, focusing on braking response.
6
Use a brake pad gauge to measure the remaining thickness of the brake pads, if accessible.

Solution

Solution

1. Preparation

Tools Required:
- Jack and jack stands
- Lug wrench
- Brake pad gauge
- Torque wrench
- Ratchet and socket set
Sub-steps:
1. Ensure the vehicle is parked on a level surface and the ignition is off.
2. Engage the parking brake and place wheel chocks behind the rear wheels.
3. Gather all necessary tools and replacement parts.

2. Raise the Vehicle

Sub-steps:
1. Loosen the lug nuts on the front wheels slightly.
2. Use the jack to lift the front of the vehicle and secure it with jack stands.
3. Remove the lug nuts completely and take off the front wheels.

3. Remove Brake Calipers

Sub-steps:
1. Locate the caliper mounting bolts and remove them using a ratchet and socket.
2. Carefully slide the caliper off the brake rotor and support it using a bungee cord or rope to avoid straining the brake line.
- Safety Warning: Do not let the caliper hang by the brake line.

4. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the old brake pads from the caliper bracket.
2. Measure the thickness of the old pads. Replace if below the manufacturer's minimum thickness (usually around 3mm).
3. If replacing, install the new pads in the caliper bracket, ensuring they are seated correctly.
4. Before reassembling, check the condition of the brake rotor; replace if necessary.

5. Reassemble the Brake Assembly

Sub-steps:
1. Carefully reposition the caliper over the new brake pads.
2. Reinstall and torque the caliper mounting bolts to the manufacturer’s specifications (typically around 20-25 ft-lbs).
3. Reinstall the wheels and hand-tighten the lug nuts.

6. Lower the Vehicle and Finalize Installation

Sub-steps:
1. Lower the vehicle from jack stands using the jack.
2. Once on the ground, tighten the lug nuts in a crisscross pattern to the manufacturer’s torque specifications (typically around 75-85 ft-lbs).
3. Pump the brake pedal several times to seat the new pads against the rotor.
