Important safety information - read before proceeding

•Always disconnect the battery before working on the braking system.
•Ensure the vehicle is securely supported on jack stands before working underneath.

Symptoms

•Steering wheel vibration when braking
•Pulsation felt in the brake pedal
•Uneven wear on brake pads or rotors
•Vehicle pulling to one side during braking
•Noises such as grinding or squeaking from the brakes

Diagnostic Steps

1
Inspect the brake rotors for warping or uneven wear using a runout gauge.
2
Check the brake pads for wear and ensure they are properly installed.
3
Examine the brake calipers for proper functioning and alignment.
4
Inspect suspension components, including control arms and tie rods, for wear or damage.
5
Check tire condition and pressure for any abnormalities.
6
Perform a road test to replicate the shaking and observe under different conditions.

Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, runout gauge, torque wrench, brake cleaner
Lift the vehicle using a jack and secure it with jack stands. Remove the wheels using a lug wrench.

2. Inspect and Replace Brake Rotors

Sub-steps:
1. Remove the brake caliper by unbolting it from the bracket and hang it using a wire to avoid stress on the brake line.
2. Take off the brake pads from the caliper bracket.
3. Use a runout gauge to measure the thickness of the rotors at multiple points. If the runout exceeds manufacturer specifications, replace the rotors.
4. Clean the hub surface where the rotor mounts using brake cleaner to ensure proper seating.
5. Install new rotors, torquing them to the manufacturer's specified torque value.

3. Install New Brake Pads

Sub-steps:
1. Apply brake grease to the back of the new brake pads to reduce noise and ensure smooth operation.
2. Install the brake pads into the caliper bracket.
3. Reattach the brake caliper over the new pads and torque the bolts to the specified torque value.

4. Inspect Suspension Components

Sub-steps:
1. Check all suspension components for play or damage, particularly control arms and tie rods.
2. Replace any worn or damaged components as necessary.

5. Reassemble and Lower Vehicle

Sub-steps:
1. Reinstall the wheels and hand-tighten the lug nuts.
2. Lower the vehicle from the jack stands.
3. Torque the lug nuts to the manufacturer’s specifications.
