⚠️ Safety Warnings

Important safety information - read before proceeding

•Always work on a level surface and use jack stands to secure the vehicle.
•Allow brakes to cool before working on them, as they can become very hot during use.

Symptoms

•Loud grinding or squealing noise when braking
•Vibration in the brake pedal
•Decreased braking performance
•Warning light on the dashboard (if applicable)
•Uneven wear on brake pads or rotors

Diagnostic Steps

1
Inspect the brake pads for wear and thickness.
2
Check the brake rotors for scoring or warping.
3
Examine brake hardware (calipers, shims, and clips) for damage or corrosion.
4
Use a multimeter to test brake pad wear sensors (if equipped).
5
Inspect brake fluid level and condition in the master cylinder.
6
Check for debris or foreign objects lodged in the brake assembly.

Solution

Solution

1. Preparation

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

2. Remove Wheel

Use a lug wrench to loosen the wheel lug nuts.
Raise the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket set.
Carefully lift the caliper off the rotor (support it with a bungee cord to avoid strain on the brake line).
Inspect the brake pads for wear; if worn below specifications (usually 3mm), replace them.
Replace with new brake pads, ensuring proper orientation.
Reinstall the caliper and torque bolts to manufacturer specifications (usually 20-30 ft-lbs).

4. Inspect and Replace Brake Rotors (if necessary)

Check the rotor surfaces for scoring or warping.
If damaged, remove the rotor by unscrewing the retaining screws or caliper bracket.
Install new rotors, ensuring they are clean and free of grease.
Torque any retaining screws to manufacturer specifications.

5. Reassemble and Reinstall Wheel

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands.
Torque the lug nuts to the manufacturer’s specifications (usually 80-100 ft-lbs).

6. Test Brakes

Pump the brake pedal to ensure proper seating of the new pads.
Test drive the vehicle at low speed to check for noise and braking effectiveness.
