Important safety information - read before proceeding

•Always disconnect the battery before working on the braking system that includes electronic components.
•Ensure the vehicle is securely supported before working underneath it.

Symptoms

•Grinding noise when applying brakes
•Vibration felt in the brake pedal
•Reduced braking efficiency
•Brake warning light illuminated on the dashboard
•Possible squeaking noises when brakes are not applied

Diagnostic Steps

1
Inspect brake pads for wear and thickness using a visual inspection.
2
Check brake rotors for scoring or warping by measuring rotor thickness and runout.
3
Examine brake calipers for proper operation and signs of sticking or damage.
4
Inspect brake lines for leaks or damage.
5
Scan for any error codes related to the braking system using an OBD-II scanner.

Solution

Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, socket set, torque wrench, brake cleaner, and safety glasses.
Place the vehicle on a level surface and engage the parking brake.
Loosen the lug nuts on the front wheels slightly with the lug wrench.

2. Lift Vehicle

Raise the vehicle with a jack and secure it on jack stands.
Remove the front wheels using the lug wrench.

3. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper bolts using the socket set.
2. Carefully slide the caliper off the rotor, supporting it to avoid tension on the brake line.
3. Remove the old brake pads from the caliper bracket.
4. Inspect the brake pad backing for wear indicators. Replace pads if they are worn down to below 3mm.
5. Apply brake grease to the backing of the new pads and install them.
6. Reattach the caliper over the new pads and tighten the caliper bolts to the manufacturer’s specified torque.

4. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
1. Check the rotors for grooves or scoring.
2. If damaged beyond the acceptable thickness (typically below 24mm), remove the rotor by unscrewing the retaining screws, if present, or pulling it off the hub.
3. Install the new rotor and secure it properly.
4. Clean the new rotor surface with brake cleaner before reinstalling the caliper.

5. Reassemble and Lower Vehicle

Replace the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and tighten lug nuts fully to the manufacturer’s torque specifications.
