•Allow the vehicle and components to cool before starting to avoid burns.

Symptoms

•Pulsating brake pedal during braking
•Increased stopping distance
•Possible vibration or noise from the brake system
•Brake warning light may illuminate
•Uneven wear on brake pads or rotors

Diagnostic Steps

1
Inspect brake rotors for warping or uneven wear using a dial indicator.
2
Check brake pad thickness and condition; replace if worn beyond specifications.
3
Verify brake fluid level and quality; bleed the brakes if necessary.
4
Examine the wheel bearings for play or damage that may affect braking performance.
5
Scan for any relevant error codes using an OBD-II scanner.

Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the ignition is off.
Gather necessary tools and parts.
Tools Required: Jack and jack stands, lug wrench, dial indicator, torque wrench, brake fluid, brake cleaner, OBD-II scanner.

2. Remove Wheel

Loosen the lug nuts slightly while the vehicle is still 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

Inspect Rotors:
- Use a dial indicator to measure any warping on the rotors. If warping exceeds specifications (typically 0.002 inches), replace the rotors.
Brake Pads:
- Measure the thickness of the brake pads. Replace pads if they are worn down to less than 3mm.
Cleaning:
- Clean the rotors and calipers with brake cleaner to remove dust and debris.

4. Reassemble Brake Components

If rotors or pads were replaced, install the new components, ensuring they are seated properly.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and use a torque wrench to tighten the lug nuts to the manufacturer's specified torque (usually around 80-100 ft-lbs, depending on the model).

5. Brake System Check

If brake fluid was low, check for leaks in the brake lines and bleed the brakes to remove air.
Refill with the manufacturer-recommended brake fluid type.
