2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Always disconnect the battery before working on electrical systems related to ABS.
•Allow the vehicle to cool down before working on brake components to prevent burns.

Symptoms

•Pulsating sensation through the brake pedal when braking
•Uneven brake wear
•Vibration in the steering wheel during braking
•Increased stopping distance
•Possible noise during braking, such as grinding or squeaking

Diagnostic Steps

1
Inspect brake rotors for warping or uneven wear.
2
Check brake pads for thickness and even wear patterns.
3
Measure rotor thickness using a micrometer to ensure they are within specifications.
4
Examine brake calipers for sticking or malfunctioning.
5
Inspect wheel bearings for play or wear that could contribute to pulsation.

2
Check brake pads for thickness and even wear patterns.
3
Measure rotor thickness using a micrometer to ensure they are within specifications.
4
Examine brake calipers for sticking or malfunctioning.
5

Solution

1. Preparation

Gather tools and parts required.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety glasses and gloves.

2. Remove Wheel

Loosen lug nuts with a socket wrench.
Jack up the vehicle and secure it on jack stands.
Remove the wheel to access the brake components.

3. Inspect and Replace Brake Rotors

Sub-steps:
- Use a caliper tool to measure the rotor thickness.
- If rotors are warped or below minimum thickness, remove the caliper bolts and detach the caliper.
- Remove the rotor by unscrewing any retaining screws or pulling it off the hub.
- Install new rotors, ensuring they are properly seated.
Tools Required: Socket set, torque wrench, caliper tool.

4. Inspect and Replace Brake Pads

Sub-steps:
- Remove the brake pads from the caliper bracket.
- Check for uneven wear; replace pads if necessary.
- Apply brake grease to the back of the new pads and install them into the caliper bracket.
Tools Required: Piston tool, brake grease.

5. Reassemble Components

Reattach the brake caliper over the new pads and rotor.
Tighten caliper bolts to the manufacturer’s specified torque.
Reinstall the wheel and tighten lug nuts in a star pattern.

6. Lower Vehicle

Remove jack stands and lower the vehicle.
Tighten lug nuts to the specified torque while the vehicle is on the ground.
