Brakes

Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Always disconnect the battery before performing work on electrical components.
•Allow the brakes to cool before inspection to avoid burns.

Symptoms

•Strong vibration felt through the steering wheel when braking
•Pulsation in the brake pedal
•Increased stopping distance
•Noise during braking (e.g., grinding or squeaking)
•Uneven tire wear

Diagnostic Steps

1
Inspect brake rotors for warping or scoring using a micrometer or caliper.
2
Check brake pads for uneven wear or thickness.
3
Examine suspension components (e.g., control arms, ball joints) for wear or damage.
4
Inspect wheel bearings for play or damage by shaking the wheel.
5
Check the lug nut torque on the wheels to ensure they are properly tightened.

Diagnostic Steps

1
Inspect brake rotors for warping or scoring using a micrometer or caliper.
2
Check brake pads for uneven wear or thickness.
3
Examine suspension components (e.g., control arms, ball joints) for wear or damage.
4
Inspect wheel bearings for play or damage by shaking the wheel.
5
Check the lug nut torque on the wheels to ensure they are properly tightened.

Solution

1. Preparation

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

2. Remove Wheel

Loosen the lug nuts slightly while the vehicle is on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Completely remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Components

Brake Rotors

Inspect: Check the rotor surface for warping or scoring using a micrometer.
Replace: If warped beyond specification (usually more than 0.002 inches), replace with new rotors.
- Tools: Rotor puller, torque wrench
- Torque Value: Typically 90-100 ft-lbs for lug nuts when reinstalling.

Brake Pads

Inspect: Measure the thickness of brake pads. Replace if below 3mm or unevenly worn.
Replace: Remove old pads and install new ones.
- Tools: C-clamp (to compress caliper), socket set

4. Reassemble

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the specified value.
Repeat for the other side if necessary.
