Affected Component

Brakes

Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Always allow the vehicle to cool before working on the brakes.
•Ensure the parking brake is engaged and the vehicle is securely supported before working underneath it.

Symptoms

•Vibrations felt through the steering wheel or brake pedal during braking
•Uneven wear on brake pads
•Potential grinding or squeaking noise when braking
•Increased stopping distance
•Vehicle pulling to one side during braking

Diagnostic Steps

1
Inspect brake pads for wear and thickness using a caliper.
2
Check brake rotors for warping by measuring runout with a dial indicator.
3
Examine brake calipers for proper operation and any signs of sticking or leakage.
4
Verify wheel alignment and suspension components for wear or damage.
5
Inspect wheel bearings for play or roughness during rotation.
6
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

Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.

2. Lift the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on where the vibrations are felt.
Secure the vehicle with jack stands.

3. Remove Wheels

Use a lug wrench to remove the wheel nuts and take off the wheels for access to the braking system.

4. Inspect and Replace Brake Pads

Inspect:
- Examine the brake pads for thickness; replace if below manufacturer specifications (usually 3mm).
Replace:
- Remove the caliper bolts with a socket wrench.
- Slide the caliper off the rotor and support it using a bungee cord.
- Remove the old brake pads and install new ones.
- Reattach the caliper and torque bolts to manufacturer specifications.

5. Inspect and Resurface/Replace Rotors

Inspect:
- Measure rotor thickness and check for warping using a dial indicator.
Resurface/Replace:
- If warped beyond spec, remove the rotors.
- For resurfacing, use a brake lathe or, if replacing, install new rotors ensuring they are clean of any oil.
- Torque rotor bolts to manufacturer specifications.

6. Reassemble and Lower Vehicle

Reattach the wheels and torque lug nuts to specification.
Lower the vehicle from the jack stands and remove the jack.

7. Test the Braking System

Pump the brake pedal a few times to ensure the pads seat properly.
Test drive the vehicle at low speeds to check for vibrations during braking.

Tools Required:

Jack and jack stands
