Diagnostic Steps

1
Inspect brake pads visually for wear; compare thickness to new pads.
2
Check for any abnormal noises when applying brakes (squeaking or grinding).
3
Test brake pedal feel; note any sponginess or excessive travel.
4
Examine brake rotors for scoring, warping, or discoloration.
5
Check brake fluid level and condition in the master cylinder reservoir.
6
Inspect for leaks around brake lines and calipers.

Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Place wheel chocks behind the rear tires for safety.

2. Remove the Wheel

Use a lug wrench to loosen the lug nuts while the vehicle is on the ground.
Lift the vehicle using a jack and secure it on jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket set.
Carefully slide the caliper off the rotor; secure it with a bungee cord to prevent stress on the brake line.
Measure the thickness of the brake pads; replace them if they are less than 3mm thick.
If replacing, remove the old pads and install new pads, ensuring they are properly seated.

4. Inspect and Replace Brake Rotors (if necessary)

If rotors are scored or warped, remove them by unscrewing the rotor retaining screws.
Install new rotors or resurface the existing ones if they meet thickness specifications.
Reattach the caliper over the new pads and torque the caliper bolts to manufacturer specifications (typically around 25-30 ft-lbs).

5. Reinstall Wheel and Lower Vehicle

Place the wheel back on the hub and hand-tighten the lug nuts.
Lower the vehicle to the ground and use a torque wrench to tighten lug nuts to the manufacturer’s specification (usually 76-80 ft-lbs).

6. Test Brakes

Pump the brake pedal to ensure proper pad seating.
Test drive the vehicle at low speed to check for any abnormal noises or issues.
