Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Always use jack stands when working underneath a vehicle.
•Allow the brakes to cool before working on them to avoid burns.

Symptoms

•Grinding noise during braking
•Vibration in the brake pedal
•Increased stopping distance
•Brake warning light illuminated
•Reduced braking performance

Diagnostic Steps

1
Inspect brake pads for wear and thickness using a brake pad gauge.
2
Check brake rotors for scoring or warping by visually inspecting and measuring with a micrometer.
3
Examine the brake calipers for proper operation and any signs of sticking or leakage.
4
Look for debris or foreign objects lodged in the brake assembly.
5
Test brake fluid level and condition, ensuring it is at the proper level and not contaminated.
6
Scan for any error codes related to the braking system using an OBD-II scanner.

Solution

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and set the parking brake.
Disconnect the negative battery terminal for electrical safety.

2. Remove Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts using a socket set and take off the wheel.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket wrench.
Carefully lift the caliper and support it with a bungee cord to avoid stress on the brake line.
Inspect the brake pads for wear; if they are below the minimum thickness, remove and replace them.
- Tools Required: Torque wrench, socket set, brake pad spreader.
Install new brake pads, ensuring they are positioned correctly in the caliper.

4. Inspect and Resurface or Replace Rotors

Remove the rotor by taking off the retaining screws if applicable.
Inspect rotor surfaces for scoring, warping, or excessive wear.
If damaged, either resurface or replace the rotors.
- Tools Required: Brake rotor tool, micrometer.
Install the rotor back onto the hub.

5. Reassemble Braking System

Reattach the brake caliper over the new pads and rotor.
Tighten caliper bolts to the manufacturer’s specified torque.
Reinstall the wheel and lug nuts, tightening them in a star pattern.

6. Final Checks

Reconnect the negative battery terminal.
Lower the vehicle and pump the brake pedal to ensure proper engagement before test driving.
