⚠️ Safety Warnings

Important safety information - read before proceeding

•Always ensure the vehicle is securely elevated and supported on jack stands before working underneath.
•Allow the brake components to cool before handling to avoid burns.

Symptoms

•Shaking or vibrating of the steering wheel during braking
•Pulsation in the brake pedal
•Uneven wear on brake pads or rotors
•Possible noise (squeaking or grinding) when braking
•Vehicle pulling to one side when braking

Diagnostic Steps

1
Inspect brake pads and rotors for wear or damage.
2
Check for rotor warping using a dial indicator or runout gauge.
3
Examine suspension components, including control arms and bushings, for wear or damage.
4
Inspect wheel lug nut torque for proper tightness.
5
Test drive the vehicle to assess the condition of the brakes and observe the shaking.

Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to ensure safety while working on the vehicle.

2. Inspect and Replace Brake Pads and Rotors

Tools Required: Jack and jack stands, lug wrench, socket set, torque wrench, brake cleaner, and replacement brake pads and rotors.
Remove the wheel using the lug wrench.
Inspect the brake pads for thickness; if they are worn down to the wear indicators, replace them.
Check the rotors for scoring or grooves. If the rotor is warped (more than 0.002 inches), it should be replaced.
Remove the caliper by unbolting it and hanging it safely to avoid stressing the brake line.
Remove the old rotors by unscrewing any retaining screws and sliding them off the hub.
Clean the new rotor with brake cleaner before installation to remove any protective oil.
Install the new rotor and reattach the caliper with the correct torque specifications (usually around 70-80 ft-lbs).
Replace brake pads and ensure they are seated correctly in the caliper bracket.

3. Inspect Suspension Components

Tools Required: Socket set, torque wrench, and possibly a pry bar.
Visually inspect control arms, ball joints, and bushings for wear or damage.
Use a pry bar to check for excessive play in suspension components.
Replace any worn or damaged parts before proceeding with further testing.

4. Reassemble and Reinstall

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specification (usually around 76-80 ft-lbs).
Reconnect the battery.
