⚠️ Safety Warnings

Important safety information - read before proceeding

•Always disconnect the battery before working on electrical components.
•Allow the vehicle to cool before working on brake components to avoid burns.

Symptoms

•Vibration or shaking felt in the steering wheel during braking
•Pulsating brake pedal when applying brakes
•Uneven wear on brake pads or rotors
•Noise coming from the brakes (squeaking or grinding)
•Vehicle pulling to one side during braking

Diagnostic Steps

1
Inspect the brake rotors for warping or scoring using a run-out gauge.
2
Check brake pad thickness and condition to ensure they are not worn unevenly.
3
Examine wheel alignment and balance to rule out related issues.
4
Inspect suspension components (e.g., control arms, tie rods) for play or wear.
5
Scan for any error codes related to the braking system using an OBD-II scanner.

Solution

💡 Expert Tip

For complex repairs like this, consider taking photos at each step. This helps if you need to reverse a step or consult with a mechanic. Also, keep all removed parts organized - you may need to reference them during reassembly.

Verification

After completing the repair, verify that the issue has been resolved:

✓Test the affected component to ensure it functions correctly
✓Check for any error codes or warning lights
✓Monitor the vehicle for a few days to ensure the issue does not recur

Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and raise it using a jack.
Secure the vehicle with jack stands and remove the wheels.

2. Inspect and Replace Brake Rotors

Sub-steps:
1. Remove caliper bolts using a socket set and carefully detach the caliper from the rotor.
2. Secure the caliper to the suspension using a bungee cord or similar to prevent strain on the brake line.
3. Remove the brake rotor by unscrewing any retaining screws or clips and sliding it off the hub.
4. Inspect the rotor for warping using a run-out gauge; replace if warped beyond specifications (usually more than 0.002 inches).
5. Install new rotors, ensuring they are clean and free from grease.

3. Replace Brake Pads

Sub-steps:
1. Remove the old brake pads from the caliper bracket.
2. Apply brake grease to the backing of the new pads to prevent squeaking.
3. Install the new pads into the caliper bracket.

4. Reassemble and Test

Sub-steps:
1. Reattach the caliper over the new pads and torque the caliper bolts to manufacturer specifications (usually around 20-25 ft-lbs).
2. Reinstall the wheels and lower the vehicle.
3. Pump the brakes a few times to seat the pads against the rotors before driving.
