⚠️ Safety Warnings

Important safety information - read before proceeding

•Always use jack stands when working under a vehicle.
•Allow the vehicle to cool before working on the brake system if it has been driven recently.

Symptoms

•Squeaking or squealing noise during braking
•Vehicle pulls to one side when braking
•Vibration or pulsation in the brake pedal
•Decreased braking efficiency
•Uneven wear patterns visible on the brake pads

Diagnostic Steps

1
Visually inspect the brake pads through the wheel spokes for any noticeable uneven wear.
2
Remove the wheel to gain better access to the brake assembly for a thorough inspection.
3
Measure the thickness of the brake pads using a caliper to compare left and right sides.
4
Check the brake rotor surface for signs of scoring or uneven wear.
5
Inspect the brake caliper for proper operation, including checking for sticking or binding.

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the battery if working on electrical components.

2. Remove Wheel

Use a jack to lift the front or rear of the vehicle (depending on which brakes are being serviced).
Secure with jack stands for safety.
Use a lug wrench to remove the wheel nuts and take off the wheel.

3. Inspect Brake Pads and Rotors

Check both brake pads on the caliper for wear; compare thickness between inner and outer pads.
Use a caliper to measure the pads; replace if any pad is below the manufacturer's minimum thickness (usually around 3 mm).
Inspect the brake rotor for uneven wear or deep grooves; consider resurfacing or replacing if necessary.

4. Replace Brake Pads (if uneven wear is found)

Remove the caliper bolts using a socket wrench and lift the caliper off the rotor.
Support the caliper with a bungee cord or rope to avoid straining the brake line.
Remove the old brake pads from the caliper bracket.
Install new brake pads, ensuring they are seated correctly.

5. Reassemble Components

Reinstall the brake caliper over the new pads and torque the caliper bolts to the manufacturer's specifications (typically 20-30 ft-lbs).
Replace the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer's specifications (typically 100-150 ft-lbs).

6. Test Brake Function

Reconnect the battery if it was disconnected.
Pump the brake pedal several times to ensure the pads seat properly against the rotor.
Test drive the vehicle at low speeds to ensure proper brake function.
