Diagnostic Steps

1
Inspect the rear brake pads for wear; measure thickness with a caliper.
2
Check the brake rotors for scoring, warping, or surface rust.
3
Examine the brake calipers for proper operation and signs of sticking.
4
Inspect the brake hardware (shims, clips) for damage or corrosion.
5
Assess for dirt, moisture, or debris between the brake pad and rotor surfaces.

Solution

Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, brake cleaner, torque wrench, socket set, C-clamp, and possibly a brake pad spreader.
Safety Warnings: Ensure the vehicle is parked on a flat surface, and engage the parking brake before lifting the vehicle.

2. Remove the Wheel

Loosen the lug nuts slightly while the vehicle is on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the rear wheel.

3. Remove the Brake Caliper

Locate the caliper mounting bolts and remove them using a socket.
Carefully slide the caliper off the rotor. Support it with a bungee cord or a suitable method to avoid straining the brake line.

4. Inspect and Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Check the thickness of the pads; if they are worn below 3mm, replace them.
If replacing, install new brake pads, ensuring the noise-dampening shims are in place.

5. Inspect and Clean the Brake Rotor

Check the rotor surface for any scoring or warping. If damaged, consider resurfacing or replacing the rotor.
Clean the rotor surface with brake cleaner to remove dust and debris.
If necessary, apply a thin layer of anti-squeal brake grease to the back of the brake pads.

6. Reassemble the Brake Components

Reinstall the caliper over the new brake pads.
Torque the caliper bolts to manufacturer specifications (typically around 30 lb-ft).
Reattach the wheel and hand-tighten the lug nuts.

7. Lower the Vehicle and Tighten Lug Nuts

Lower the vehicle from the jack stands using the jack.
Fully tighten the lug nuts in a crisscross pattern to the manufacturer’s recommended torque (usually around 76 lb-ft).
