⚠️ Safety Warnings

Important safety information - read before proceeding

•Always allow the vehicle to cool before working on the brakes.
•Disconnect the battery before working on any electrical components.

Symptoms

•Shaking or vibration felt in the steering wheel or brake pedal when braking
•Increased stopping distance
•Pulsating brakes during application
•Uneven tire wear
•Potential noise such as grinding or squeaking during braking

Diagnostic Steps

1
Inspect brake rotors for warping or uneven wear using a run-out gauge.
2
Check brake pads for thickness and even wear patterns.
3
Examine suspension components (e.g., control arms, bushings) for play or damage.
4
Verify wheel alignment and balance.
5
Inspect tires for uneven wear or damage.
6
Scan for any error codes related to the braking system using an OBD-II scanner.

Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the negative battery terminal for safety.

2. Remove Wheel

Use a jack to lift the front or rear of the vehicle.
Secure with jack stands for safety.
Remove the wheel bolts using a socket set and take off the wheel.

3. Inspect and Replace Brake Rotors

Inspection:
- Measure rotor thickness and run-out with a micrometer and run-out gauge.
- Look for signs of scoring or glazing on the rotor surface.
Replacement:
- If rotors are warped or below thickness specifications, remove the caliper mounting bolts and slide off the caliper.
- Remove the rotor by unscrewing any retaining screws if present.
- Install the new rotor, ensuring it is clean from any contaminants.
- Reattach the caliper and torque the bolts to the manufacturer’s specifications (typically around 20-25 lb-ft).

4. Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Inspect the caliper for any signs of leaks or damage.
Install new brake pads into the caliper bracket, ensuring they are seated properly.
Apply brake grease on the back of the pads to reduce noise.

5. Reassemble and Test

Reattach the wheel and hand-tighten the bolts.
Lower the vehicle back to the ground and torque the wheel bolts to the manufacturer’s specifications (typically around 80-100 lb-ft).
Reconnect the negative battery terminal.
