⚠️ Safety Warnings

Important safety information - read before proceeding

•Always disconnect the battery before working on electrical components.
•Allow the brakes to cool before inspecting or working on them.

Symptoms

•Grinding noise when applying brakes
•Decreased braking efficiency
•Vibration or pulsation in the brake pedal
•Squeaking or squealing prior to grinding
•Warning light illuminated (if equipped with a brake wear sensor)

Diagnostic Steps

1
Inspect brake pads for wear and thickness using a visual inspection.
2
Check brake rotors for scoring, warping, or excessive wear.
3
Examine the brake calipers for proper operation and any signs of sticking.
4
Inspect brake hardware components (shims, clips, etc.) for corrosion or damage.
5
Check brake fluid level and condition in the master cylinder reservoir.

Diagnostic Steps

1
Inspect brake pads for wear and thickness using a visual inspection.
2
Check brake rotors for scoring, warping, or excessive wear.

Examine the brake calipers for proper operation and any signs of sticking.
4
Inspect brake hardware components (shims, clips, etc.) for corrosion or damage.

Solution

1. Preparation

Gather tools: jack, jack stands, lug wrench, socket set, torque wrench, brake cleaner, and safety glasses.
Park the vehicle on a level surface and engage the parking brake.

2. Raise the Vehicle

Loosen the lug nuts slightly while the vehicle is still on the ground.
Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Remove the brake caliper by loosening the bolts with a socket wrench.
- Tools Required: Socket set
Slide the caliper off the rotor and support it with a wire hanger (do not let it hang by the brake line).
Inspect brake pads for wear; if they are below 3mm thickness, replace them.
Remove the old pads from the caliper bracket and install new pads.
Apply brake grease to the back of the pads to reduce noise.

4. Inspect and Replace Brake Rotors (if necessary)

Check the rotor surface for grooves and scoring; if damaged, replace the rotors.
Remove rotor by unscrewing any retaining screws and sliding it off the hub.
Install new rotors, ensuring they are clean and free of grease.
Torque the rotor retaining screws to manufacturer specifications.

5. Reassemble and Test

Reattach the caliper over the new pads and rotor, tightening the bolts to the specified torque.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and fully tighten the lug nuts in a crisscross pattern to the manufacturer's torque specification.
