Affected Component

Brakes

Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Always disconnect the battery before working on electrical components.
•Allow brakes to cool before handling any components to avoid burns.

Symptoms

•Vibrations felt in the steering wheel when braking
•Pulsating brake pedal
•Increased stopping distance
•Uneven wear on brake pads or rotors
•Possible noise (squeaking or grinding) during braking

Diagnostic Steps

1
Inspect brake rotors for warping or uneven wear using a runout gauge.
2
Check brake pads for wear; measure thickness and look for uneven wear patterns.
3
Examine suspension components (e.g., control arms, tie rods) for damage or wear.
4
Verify that wheel lug nut torque is correct and that wheels are properly mounted.
5
Test drive the vehicle to replicate the vibration and assess if it occurs at specific speeds.

Solution

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety goggles and gloves.

2. Lift Vehicle

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

3. Inspect and Replace Brake Components

Inspect Rotors

Use a runout gauge to check for rotor warping.
If warped beyond manufacturer specifications (usually 0.002 inches), proceed to replace.

Replace Brake Rotors

Remove caliper mounting bolts using a socket set.
Carefully hang the caliper using a bungee cord (do not let it hang by the brake line).
Remove the brake rotor by unscrewing any retaining screws and sliding it off the hub.
Install the new rotor and secure it with retaining screws.

Replace Brake Pads

Compress the caliper piston using a brake caliper tool.
Remove the old brake pads from the caliper bracket.
Place new brake pads in the bracket, ensuring they are seated properly.
Reattach the caliper over the new pads and tighten caliper mounting bolts to manufacturer specifications (typically 25-35 ft-lbs).

4. Reassemble

Reinstall the front wheels and torque lug nuts to manufacturer specifications (typically 90-100 ft-lbs).
Lower the vehicle from the jack stands.
