Diagnostic Steps

1
Inspect the brake pads for wear and thickness using a caliper gauge.
2
Check for any debris or dirt between the brake pad and rotor.
3
Examine the brake rotors for scoring or warping.
4
Verify brake fluid level and condition in the master cylinder reservoir.

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and engage the parking brake.
Lift the rear of the vehicle using a jack and secure it with jack stands.

2. Remove Wheel

Using a lug wrench, loosen and remove the lug nuts.
Remove the wheel to access the brake assembly.

3. Inspect and Replace Brake Pads

Inspection: Check the thickness of the brake pads. If they are below 3mm, they need to be replaced.
Remove Brake Caliper:
- Using a socket set, remove the caliper bolts.
- Carefully slide the caliper off the rotor and suspend it using a bungee cord to avoid straining the brake line.
Remove Old Brake Pads: Slide out the old pads from the caliper bracket.
Install New Brake Pads:
- Apply brake grease to the backing of the new pads.
- Slide the new pads into the caliper bracket.

4. Inspect and Replace Rotors (if needed)

If rotors are scored or worn, remove them by unbolting the caliper bracket.
Clean the hub surface before installing new rotors.
Install new rotors by aligning them with the hub and securing them with bolts.

5. Reassemble Brake Components

Reattach the brake caliper over the new pads and rotor.
Tighten the caliper bolts to the manufacturer's torque specification (typically 25-30 Nm).
Replace the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Test Brakes

Lower the vehicle to the ground and remove jack stands.
Fully tighten lug nuts in a criss-cross pattern to the specified torque (typically 100 Nm).
Pump the brake pedal several times to seat the new pads.
