Affected Component

Brakes

Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Always ensure the vehicle is securely lifted and supported before working underneath.
•Allow the vehicle's brakes to cool before starting any work.

Symptoms

•Shaking or vibration felt in the steering wheel during braking
•Pulsating brake pedal
•Uneven wear on brake pads or rotors
•Increased stopping distance
•Noise during braking (squeaking or grinding)

Diagnostic Steps

1
Inspect brake rotors for warping or uneven wear using a dial indicator.
2
Check brake pads for thickness and even wear patterns.
3
Examine suspension components (e.g., control arms, tie rods) for looseness or damage.
4
Verify wheel lug nut torque to ensure proper seating of the wheel.
5
Test drive the vehicle to replicate the shaking and note the conditions (speed, braking force).

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 necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Tools Required: Jack and jack stands, lug wrench, dial indicator, torque wrench, brake cleaner, and safety goggles.

2. Inspect and Replace Brake Rotors

Step 1: Remove the wheel using the lug wrench.
Step 2: Inspect the brake rotor for warping using a dial indicator. If the runout exceeds manufacturer specifications, proceed to replace the rotor.
Step 3: Remove caliper bolts and lift the caliper off the rotor. Secure it with a bungee cord to prevent strain on the brake line.
Step 4: Remove the brake rotor from the hub. Clean the hub surface with brake cleaner.
Step 5: Install the new rotor, ensuring it seats properly on the hub.

3. Check and Replace Brake Pads

Step 1: Inspect the brake pads for wear. If they are below the minimum thickness, replace them.
Step 2: Remove the old pads from the caliper bracket by sliding them out.
Step 3: Install new brake pads, making sure they are correctly positioned in the caliper bracket.

4. Reassemble Components

Step 1: Reattach the caliper over the new rotor and pads.
Step 2: Tighten caliper bolts to the manufacturer’s specified torque.
Step 3: Reinstall the wheel and hand-tighten the lug nuts.
Step 4: Lower the vehicle off the jack stands and torque the lug nuts to the manufacturer’s specifications.

5. Final Checks

Step 1: Pump the brake pedal to seat the pads against the rotor.
Step 2: Test drive the vehicle at low speeds to ensure the shaking is resolved.
