⚠️ Safety Warnings

Important safety information - read before proceeding

•Ensure the vehicle is securely lifted and supported on jack stands before working under it.
•Allow the brakes to cool before handling components to avoid burns.

Symptoms

•Steering wheel vibrations during braking
•Pulsation felt in the brake pedal
•Uneven wear on brake pads or rotors
•Vehicle pulls to one side when braking
•Noisy brakes, such as squeaking or grinding

Diagnostic Steps

1
Inspect brake rotors for warping or uneven wear using a dial indicator.
2
Check brake pads for even thickness and signs of damage.
3
Examine suspension components, such as tie rods and control arms, for wear or damage.
4
Verify tire condition and balance; check for uneven wear or low pressure.
5
Perform a brake fluid test for contamination or moisture content.

Solution

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the parking brake engaged.
Disconnect the battery if working on electrical components.

2. Inspect and Replace Brake Rotors

Tools Required: Socket set, torque wrench, brake cleaner, dial indicator.
Remove the wheel to access the brake assembly.
Use a dial indicator to measure rotor runout; if it exceeds manufacturer specifications, proceed to replace the rotors.
Remove caliper bolts and hang the caliper using a bungee cord to avoid straining the brake line.
Remove the brake rotor by unscrewing the retaining screws (if equipped) and sliding it off the hub.
Clean the hub surface with brake cleaner before installing new rotors.
Install new rotors, ensuring they are torqued to the manufacturer's specifications.

3. Inspect and Replace Brake Pads

Remove old brake pads from the caliper bracket.
Measure pad thickness; if below the minimum thickness, replace with new pads.
Apply brake grease to the back of the new pads to prevent noise.
Reinstall the caliper and tighten bolts to the specified torque.

4. Inspect Suspension Components

Visually check all suspension components for cracks, rust, or play.
Replace any worn or damaged components such as tie rods or control arms to ensure stability during braking.

5. Verify Tire Condition and Alignment

Check tire pressure and inflate to the recommended levels.
Inspect tires for uneven wear; replace tires if necessary.
If wear patterns exist, consider performing a wheel alignment.
