Brakes

Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Always disconnect the battery before working on electrical components.
•Allow the brakes to cool before handling to prevent burns.

Symptoms

•Grinding noise when applying brakes
•Reduced braking efficiency or responsiveness
•Vibration felt in the brake pedal
•Brake warning light illuminated on the dashboard
•Increased stopping distance

Diagnostic Steps

1
Inspect the brake pads for wear and damage using a visual inspection method.
2
Check brake rotors for warping or scoring by measuring rotor thickness and inspecting surface condition.
3
Examine brake calipers for proper functioning, ensuring they are not sticking or leaking.
4
Inspect brake fluid level and condition; check for contamination.
5
Test drive the vehicle to replicate the grinding noise and assess braking performance.

Solution

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and set the parking brake.
Wear safety goggles and gloves for protection.

2. Remove Wheel

Loosen lug nuts on the wheel using a socket wrench.
Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Remove the caliper by unbolting it from the bracket using a socket wrench.
Carefully slide the caliper off the rotor; support it to avoid straining the brake line.
Remove the old brake pads from the caliper bracket.
Check the backing plate for wear; replace if necessary.
Install new brake pads, ensuring they are properly aligned.

4. Inspect and Replace Brake Rotors (if needed)

Check the rotor thickness with a micrometer; if below specifications, replace the rotor.
Remove the rotor by unbolting it from the hub assembly.
Clean the hub surface to ensure proper contact with the new rotor.
Install the new rotor, securing it with the appropriate bolts.

5. Reassemble and Test

Reattach the caliper over the new brake pads and secure it with bolts.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specification.
Test the brakes by pressing the pedal several times to seat the pads.
