2
Check brake rotors for scoring or warping.
3
Examine brake calipers for proper operation and any signs of sticking.
4
Inspect brake fluid level and condition.
5

Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Use wheel chocks to prevent rolling.

2. Remove Wheel

Tools Required: Socket set, lug wrench
Loosen lug nuts with the lug wrench while the vehicle is still on the ground.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Inspect the brake pads for wear indicators; if they are worn down to the metal, they need replacement.
Remove the caliper by unscrewing the caliper bolts with a socket wrench.
Carefully slide the caliper off the brake pads and hang it using a bungee cord to avoid damaging the brake line.
Remove the old brake pads from the caliper bracket.
Install new brake pads in the caliper bracket, ensuring they are properly seated.

4. Inspect and Replace Brake Rotors (if necessary)

If rotors are scored or damaged, they will need to be replaced.
Remove the caliper bracket by unscrewing the bracket bolts.
Pull the rotor off the hub. If it’s stuck, gently tap it with a rubber mallet.
Clean the hub surface with a wire brush to remove rust and debris.
Install the new rotor onto the hub, ensuring it is flush against the surface.

5. Reassemble Components

Reattach the caliper bracket over the new rotor.
Secure the caliper back onto the bracket using the caliper bolts, tightening to manufacturer specifications (typically around 25-35 lb-ft).
Replace the wheel, hand-tightening the lug nuts before lowering the vehicle.

6. Final Checks

Lower the vehicle and fully tighten the lug nuts in a crisscross pattern to ensure even pressure.
Pump the brake pedal several times to seat the brake pads properly.
