Important safety information - read before proceeding

•Always use jack stands when working under a vehicle.
•Allow the vehicle to cool before working on the braking system.

Symptoms

•Steering wheel shakes during braking
•Vibration felt in the brake pedal
•Uneven brake pad wear
•Increased stopping distance
•Possible noise (grinding or squeaking) when braking

Diagnostic Steps

1
Inspect front brake rotors for warping by measuring thickness with a micrometer.
2
Check brake pads for wear and ensure they are within manufacturer's specifications.
3
Examine suspension components including control arms and bushings for wear or damage.
4
Inspect wheel lug nut torque to ensure they are properly tightened.
5
Perform a visual inspection of the brake calipers for proper operation and any leakage.
6
Check tire balance and alignment to rule out other causes of shaking.

Solution

1. Preparation

Gather necessary tools: jack, jack stands, lug wrench, micrometer, socket set, and torque wrench.
Park the vehicle on a level surface, engage the parking brake, and allow the engine to cool.

2. Raise the Vehicle

Use the jack to lift the front of the vehicle and secure it with jack stands.
Remove the front wheels using a lug wrench.

3. Inspect and Replace Brake Rotors

Inspect Rotors:
- Use a micrometer to measure rotor thickness; replace if below specifications.
Replace Rotors:
- Remove the caliper bolts and slide the caliper off the rotor.
- Remove the rotor retaining screws, if applicable, and slide the rotor off the hub.
- Install the new rotor, ensuring it is properly aligned and secured.
- Reinstall the caliper over the new rotor and tighten caliper bolts to manufacturer specifications.

4. Inspect and Replace Brake Pads

Remove the caliper from the rotor as described above.
Remove the old brake pads from the caliper bracket.
Install new brake pads, ensuring they are correctly positioned and secured.
Use a C-clamp to compress the caliper piston if necessary to fit over the new pads.

5. Reassemble and Lower Vehicle

Reinstall the front wheels and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and torque the lug nuts to the manufacturer’s specifications.
If suspension components were inspected and found faulty, replace them as needed following the respective service manual.

6. Test the Brakes

Start the vehicle and pump the brake pedal to ensure the calipers are properly seated.
Conduct a test drive at low speeds to check for any remaining vibrations.
