Diagnostic Steps

1
Inspect brake pads for wear and tear using a visual inspection.
2
Check brake rotors for scoring or warping.
3
Examine brake calipers for proper operation and signs of sticking.
4
Inspect brake fluid level and condition in the master cylinder.

Solution

1. Preparation

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

2. Remove Wheel

Use a lug wrench to loosen the lug nuts but do not completely remove them.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Inspect Brake Pads: Check the thickness of the brake pads. If they are worn down to less than 3mm, they need to be replaced.
Remove Brake Caliper:
- Use a socket set to remove the caliper mounting bolts.
- Carefully slide the caliper off the brake rotor and secure it with a bungee cord to avoid stress on the brake line.
Replace Brake Pads:
- Remove old brake pads from the caliper bracket.
- Install new brake pads, ensuring they are properly seated.

4. Inspect and Replace Brake Rotors (if needed)

Check Rotors: Measure the thickness of the rotors. If they are below the minimum thickness specification or show excessive scoring, replace them.
Remove Old Rotors:
- If rotors need replacing, remove the rotor retaining screws (if applicable).
- Slide the rotor off the wheel hub.
Install New Rotors:
- Clean the new rotor's surface with brake cleaner to remove any protective coating.
- Install the new rotor onto the hub and secure it.

5. Reassemble Braking System

Reattach the caliper over the new brake pads and rotor.
Tighten the caliper mounting bolts to manufacturer specifications (typically 20-30 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Test

Carefully lower the vehicle and remove the jack stands.
Tighten the lug nuts in a crisscross pattern to the manufacturer’s torque specs (usually 80-100 ft-lbs).
Test drive the vehicle at low speeds to ensure proper brake function.
