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 the vehicle to cool before working on the braking system.

Symptoms

•Vibration or pulsation felt through the brake pedal
•Steering wheel shaking during braking
•Reduced braking effectiveness
•Uneven wear on brake pads
•Noise (grinding or squeaking) when brakes are applied

Diagnostic Steps

1
Inspect brake rotors visually for signs of warping or uneven wear.
2
Check brake pads for uneven wear and thickness.
3
Measure rotor thickness with a micrometer to ensure they are within service limits.
4
Verify that wheel lug nuts are properly torqued.
5
Test drive the vehicle to confirm pulsation occurs during braking.

Solution

Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, brake cleaner, micrometer, torque wrench, and impact wrench.
Safely elevate the vehicle and remove the wheel using a lug wrench.
Ensure the vehicle is on a level surface and secured before beginning work.

2. Remove Brake Components

Sub-steps:
1. Remove the caliper bolts using a socket set.
2. Carefully slide the caliper off the rotor and support it with a bungee cord or rope to avoid straining the brake line.
3. Remove the brake pads from the caliper bracket.

3. Inspect and Replace Rotors

Sub-steps:
1. Measure the rotor thickness with a micrometer; if below the minimum thickness specification, replace the rotor.
2. If the rotor is above the minimum thickness but warped, consider having it resurfaced by a professional or replace it.
3. Clean the hub surface with brake cleaner to remove any rust or debris before installing new or resurfaced rotors.
4. Install the new or resurfaced rotor onto the hub, ensuring it is seated properly.

4. Reassemble Brake Components

Sub-steps:
1. Reinstall the brake pads into the caliper bracket.
2. Slide the caliper back over the brake pads and rotor.
3. Reinstall the caliper bolts and torque them to the manufacturer's specifications.
4. Reinstall the wheel and lower the vehicle, then torque the lug nuts to the specified torque.

5. Final Checks

Sub-steps:
1. Pump the brake pedal several times to ensure proper brake pad seating against the rotor.
2. Check brake fluid levels and top off if necessary.
