⚠️ Safety Warnings

Important safety information - read before proceeding

•Ensure the vehicle is securely supported before working underneath.
•Allow brake components to cool before handling, as they can become extremely hot during operation.

Symptoms

•Steering wheel vibrates when braking
•Pulsation felt in the brake pedal
•Vehicle pulls to one side during braking

•Increased stopping distance

Diagnostic Steps

1
Inspect brake rotors visually for warping or uneven wear.
2
Check wheel alignment and tire condition for imbalance or uneven wear.
3
Measure rotor thickness with a micrometer to ensure they are within manufacturer specifications.
4
Scan for any error codes related to the braking system using an OBD-II scanner.
5
Inspect brake pads for wear and ensure they are not glazed or damaged.
6
Verify the condition of the suspension components, including control arms and bushings.

Solution

Solution

1. Preparation

Gather tools and materials.
Ensure vehicle is on a flat surface and engage the parking brake.
Disconnect the battery if necessary for electrical safety.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Rotors

Remove brake caliper by unbolting it from the bracket (use a socket set).
Support the caliper with a bungee cord or similar device to avoid strain on the brake line.
Remove brake pads from the caliper bracket.
Use a micrometer to measure rotor thickness; if below specifications or warped, proceed to replace.
Remove the rotor by unscrewing any retaining screws and pulling it off the hub.
Install new rotor (ensure it is clean and free of contaminants).

4. Replace Brake Pads

Install new brake pads into the caliper bracket.
Reattach the brake caliper over the pads, ensuring it is properly aligned and bolts are torqued to manufacturer's specifications.
Replace the wheel and hand-tighten the lug nuts.

5. Reassemble and Lower Vehicle

Lower the vehicle back to the ground.
Torque the lug nuts to the manufacturer’s specifications.
Reconnect the battery if it was disconnected.
