Affected Component

Brakes

Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect the battery before working on electrical systems.
•Allow the brakes to cool before working on them after driving.

Symptoms

•Shaking or vibrating felt in the steering wheel during braking
•Increased pedal pulsation when applying brakes
•Uneven tire wear
•Vehicle pulls to one side when braking
•Potential noise from brakes or suspension components

Diagnostic Steps

1
Inspect brake rotors for warping or uneven wear using a dial indicator.
2
Check brake pads for thickness and even wear across the surface.
3
Examine wheel bearings for play or looseness.
4
Inspect suspension components (control arms, tie rods, bushings) for wear or damage.
5
Check tire balance and alignment to rule out issues unrelated to the braking system.
6
Scan for any related error codes using an OBD-II scanner.

Solution

Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery to avoid electrical shorts while working on the vehicle.

2. Remove the Front Wheels

Loosen lug nuts slightly while the vehicle is still on the ground.
Raise the front of the vehicle using a jack and secure with jack stands.
Remove the front wheels completely.

3. Inspect and Replace Brake Rotors

Sub-steps:
1. Remove the brake caliper by unbolting it from the bracket and hanging it securely with a bungee cord.
2. Remove the brake pads from the caliper bracket.
3. Use a rotor puller if necessary to remove the old rotor.
4. Clean the hub surface and install the new rotor, ensuring it sits flush.
Tools Required: Socket set, torque wrench, bungee cord, rotor puller (if needed).
Safety Warnings: Ensure the brake caliper does not hang by the brake line to avoid damage.

4. Replace Brake Pads

Sub-steps:
1. Check the new brake pads for proper fit and thickness.
2. Apply brake grease to the back of the pads and the caliper slides.
3. Install the new brake pads into the caliper bracket.
4. Reattach the brake caliper over the new pads and torque bolts to manufacturer specifications.
Tools Required: Socket set, torque wrench.

5. Reinstall Wheels and Lower Vehicle

Sub-steps:
1. Place the front wheels back onto the hub and hand-tighten the lug nuts.
2. Lower the vehicle and torque the lug nuts to the manufacturer's specifications.
Tools Required: Torque wrench.

6. Test Drive

After the repair, take the vehicle for a test drive to ensure the shaking has been resolved.
Monitor braking performance and check for any unusual noises.
