⚠️ Safety Warnings

Important safety information - read before proceeding

•Always ensure the vehicle is securely lifted and supported before working under it.
•Allow the brakes to cool before touching any components if the vehicle has been driven recently.

Symptoms

•Grinding noise when applying brakes
•Reduced braking efficiency
•Vibration in the brake pedal
•Warning light illuminated on the dashboard
•Brake dust accumulation on the wheels

Diagnostic Steps

1
Inspect brake pads for wear and thickness using a visual inspection.
2
Check brake rotors for scoring or damage by measuring rotor thickness and surface condition.
3
Examine brake calipers for proper operation and signs of sticking or seizing.
4
Verify brake fluid level and condition in the master cylinder reservoir.
5
Inspect brake lines for leaks or damage.

Solution

Diagnostic Steps

1
Inspect brake pads for wear and thickness using a visual inspection.
2
Check brake rotors for scoring or damage by measuring rotor thickness and surface condition.
3
Examine brake calipers for proper operation and signs of sticking or seizing.
4
Verify brake fluid level and condition in the master cylinder reservoir.
5

Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety gloves and goggles.

2. Remove Wheel

Loosen the lug nuts on the wheel associated with the grinding noise.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Sub-step 1: Remove the caliper bolts using a socket set (typically 14mm or 15mm).
Sub-step 2: Carefully slide the caliper off the rotor and suspend it with a bungee cord to avoid stressing the brake line.
Sub-step 3: Remove the old brake pads from the caliper bracket.
Sub-step 4: Inspect the brake pad backing for signs of wear or damage.
Sub-step 5: Install new brake pads into the caliper bracket, ensuring they are properly seated.

4. Inspect and Replace Brake Rotors (if necessary)

Sub-step 1: Measure the rotor thickness with a micrometer; if below the minimum specification, replace the rotors.
Sub-step 2: Remove the caliper bracket bolts and detach the bracket.
Sub-step 3: Slide the rotor off the wheel hub. If stuck, gently tap with a rubber mallet.
Sub-step 4: Install new rotors, ensuring they are clean from any protective oil.

5. Reassemble Brake Components

Sub-step 1: Reattach the caliper bracket and torque the bolts to the manufacturer specifications (typically around 25-30 ft-lbs).
Sub-step 2: Reinstall the caliper over the new brake pads and torque caliper bolts to specifications.
Sub-step 3: Reinstall the wheel and hand-tighten the lug nuts.
Sub-step 4: Lower the vehicle and then torque the lug nuts to the specified value (usually 100-110 ft-lbs).

6. Final Checks

Pump the brake pedal several times to ensure proper pad seating and brake operation.
Check brake fluid level again and top off as necessary.
