Affected Component

Brakes

Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Always disconnect the battery before working on electrical systems.
•Allow the vehicle to cool before working on brake components.

Symptoms

•Noticeable squeaking or grinding noise during braking
•Vibration or pulsation in the brake pedal
•Pulling to one side when braking
•Uneven thickness of brake pads upon inspection
•Increased stopping distance

Diagnostic Steps

1
Visual Inspection of Brake Pads: Remove the wheel and visually inspect the brake pads for uneven wear patterns.
2
Measure Brake Pad Thickness: Use a caliper to measure the thickness of each brake pad on both front and rear axles.
3
Check Brake Caliper Functionality: Inspect the brake calipers for proper movement and ensure they aren't sticking or seizing.
4
Examine Brake Rotors: Check the rotors for warping or uneven surfaces that may contribute to uneven pad wear.
5
Assess Suspension Components: Inspect the suspension components for wear or damage that could affect brake alignment.
6
Test Drive the Vehicle: Conduct a test drive to feel for pulling or vibrations when applying the brakes.

Solution

Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, caliper gauge, brake cleaner, protective gloves, safety goggles.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Remove Wheel

Loosen the lug nuts with a lug wrench.
Lift the vehicle using a jack and secure with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Inspect Brake Pads: Check for uneven wear patterns and measure the thickness.
Remove Caliper: Unbolt the caliper from its bracket using a socket set. Support the caliper with a hangar to avoid stress on the brake line.
Remove Old Brake Pads: Slide the brake pads out of the caliper bracket.
Install New Brake Pads: Insert new brake pads, ensuring they are compatible with the vehicle specifications.
Reassemble Caliper: Reattach the caliper over the new pads and torque the bolts to manufacturer specifications (usually around 20-25 ft-lbs).

4. Replace or Resurface Rotors (if necessary)

Inspect Rotors: Check for warping or scoring.
If uneven, either replace the rotors or have them resurfaced to ensure a flat surface.
Install the rotors back onto the hub and secure them.

5. Reinstall Wheel

Place the wheel back onto the hub.
Hand-tighten the lug nuts and then lower the vehicle.
After lowering, use the torque wrench to tighten the lug nuts to the manufacturer’s recommended torque (usually around 100-120 ft-lbs).

6. Test and Clean

Test Drive: Conduct a short test drive to ensure brakes function correctly without pulling or noise.
Clean Up: Ensure all tools are removed from the work area and dispose of old brake pads and materials responsibly.
