Check for uneven wear on brake pads; one side may be significantly thinner than the other.
3
Test the brake pedal feel; it should be firm and responsive.
4
Drive the vehicle and assess for pulling to one side during braking.
5
Measure the temperature of each wheel after a short drive to identify overheating.
6
Inspect brake fluid levels and condition in the master cylinder reservoir.

Solution

Solution

1. Preparation

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

2. Raise the Vehicle

Use a jack to lift the front of the vehicle and secure it with jack stands.
Remove the front wheels using a lug wrench.

3. Inspect the Brake Calipers

Remove the caliper mounting bolts using a socket set.
Carefully slide the caliper off the brake rotor.
Inspect the caliper slides and pistons for signs of sticking or rust.
Clean any corrosion with brake cleaner and a wire brush if necessary.

4. Lubricate Caliper Slides

Apply a high-temperature brake grease to the caliper slide pins.
Reassemble the caliper onto the rotor, ensuring it moves freely.
Torque the caliper mounting bolts to the manufacturer’s specifications.

5. Replace Parts if Necessary

If calipers are damaged or seized, replace them with new calipers.
Use new brake pads if they are worn unevenly.

6. Reassemble and Test

Reinstall the wheels and lower the vehicle.
Pump the brake pedal to ensure proper caliper function.
Test drive the vehicle to assess brake operation.
