⚠️ Safety Warnings

Important safety information - read before proceeding

•Ensure the vehicle is on a flat surface, engage the parking brake, and wear safety glasses and gloves.
•Disconnect the battery before working on electronic brake systems if applicable.
•Allow the brakes to cool before working on them.

Symptoms

•Noticeable vibrations or pulsations during braking
•Increased brake noise (squeaking or grinding)
•Uneven thickness of brake pads (visibly different wear)
•Pulling to one side during braking
•Warning light for brake system on the dashboard (if equipped)

Diagnostic Steps

1
Inspect brake pads for uneven wear visually and measure thickness with calipers.
2
Check brake calipers for proper operation; ensure they are not sticking or seizing.
3
Examine brake rotors for warping or uneven wear.
4
Inspect suspension components for wear or misalignment, including control arms and bushings.
5
Test brake fluid for contamination or air bubbles that may affect braking performance.

Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, torque wrench, brake cleaner, caliper tool, multimeter (for electronic components), measuring calipers.
Safety Warnings: Ensure the vehicle is on a flat surface, engage the parking brake, and wear safety glasses and gloves.

2. Remove Wheel

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

3. Inspect and Replace Brake Components

Inspect Brake Pads:
- Remove the caliper bolts using a socket set.
- Carefully lift the caliper off the rotor and secure it with a wire or bungee cord to avoid stress on the brake line.
- Remove the old brake pads and inspect their surfaces.
Check Brake Rotor:
- Measure rotor thickness with calipers to ensure it’s within specifications.
- Look for signs of warping or scoring; replace if necessary.
Replace Brake Pads if Necessary:
- Clean the caliper bracket and apply brake grease to the backing of the new pads.
- Install new brake pads, ensuring they are seated properly.
Check and Service Brake Calipers:
- Inspect caliper slides for smooth operation; lubricate if necessary.
- If the caliper is sticking, consider rebuilding or replacing it.

4. Reassemble and Torque

Reinstall the caliper and torque bolts to manufacturer specifications (typically around 20-30 ft-lbs).
Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and fully tighten lug nuts in a star pattern to the manufacturer’s torque specification (usually 76-85 ft-lbs).
