⚠️ Safety Warnings

Important safety information - read before proceeding

•Always ensure the vehicle is securely supported on jack stands before working underneath it.
•Allow the brake components to cool before touching them, as they can become very hot during use.

Symptoms

•Grinding noise when applying brakes
•Reduced braking performance
•Vibration felt through the brake pedal
•Warning light on the dashboard (if equipped)
•Increased stopping distance

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 brake calipers for proper function and any signs of sticking.
4
Inspect brake lines for leaks or damage.
5
Check brake fluid level and condition in the master cylinder reservoir.
6
Use an OBD-II scanner to check for any ABS-related error codes.

Solution

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the parking brake engaged.
Use wheel chocks to prevent movement.
Disconnect the negative battery terminal for safety.

2. Remove Wheel

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

3. Inspect and Replace Brake Pads

Inspection: Check the brake pads for wear indicators. If they are less than 1/8 inch thick, they should be replaced.
Removal:
- Remove the caliper bolts using a socket wrench.
- Slide the caliper off the rotor and support it with a bungee cord or rope to avoid straining the brake line.
- Remove the old brake pads from the caliper bracket.
Installation:
- Place new brake pads into the caliper bracket.
- Reinstall the caliper over the new pads and secure it with the caliper bolts. Torque to manufacturer specifications (typically around 25-30 ft-lbs).

4. Inspect and Replace Rotors (if needed)

Inspection: Check rotors for grooves or warping. If damaged, replace them.
Removal:
- If necessary, remove the caliper bracket by unscrewing the bracket bolts.
- Slide the rotor off the hub.
Installation:
- Install the new rotor onto the hub.
- Reinstall the caliper bracket and torque the bolts to manufacturer specifications.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and use a torque wrench to tighten the lug nuts to the specified torque (typically 100-150 ft-lbs).
Reconnect the negative battery terminal.
