Affected Component

Brakes

Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Ensure the vehicle is on a flat surface and securely lifted before starting work.
•Always disconnect the battery before working on the braking system to prevent any electrical issues.

Symptoms

•Uneven brake pad thickness on one or more wheels
•Squeaking or grinding noise during braking
•Vehicle pulling to one side while braking
•Increased stopping distance
•Brake warning light illuminated on the dashboard

Diagnostic Steps

1
Inspect Brake Pads: Remove the wheel and visually inspect the brake pads for uneven wear patterns.
2
Check Caliper Functionality: Verify that the brake calipers are moving freely and not seizing.
3
Examine Brake Rotors: Inspect the brake rotors for warping, scoring, or uneven surfaces that may affect pad wear.
4
Brake Line Inspection: Check brake lines for leaks or blockages that could affect brake fluid flow to the calipers.
5
Assess Suspension Components: Inspect suspension parts (e.g., control arms, bushings) for wear that could affect alignment and brake function.
6
Check Alignment: Perform a wheel alignment to determine if misalignment is contributing to uneven brake wear.

Solution

Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, brake cleaner, torque wrench.
Safety Warnings: Ensure the vehicle is on a flat surface and securely lifted before starting work.

2. Remove Wheel

Loosen the lug nuts slightly before raising the vehicle.
Use the jack to lift the vehicle and place it on jack stands.
Completely remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket wrench and slide the caliper off the rotor.
Remove the old brake pads from the caliper bracket.
Clean the caliper bracket and rotor with brake cleaner.
Install new brake pads ensuring they are the correct size and type for the vehicle.
Reattach the caliper over the new pads and torque the caliper bolts to manufacturer specifications.

4. Inspect and Replace Calipers (if necessary)

If calipers are found to be seized or malfunctioning during inspection, remove the caliper from the bracket.
Disconnect the brake line from the old caliper using a flare wrench.
Install the new caliper and reconnect the brake line, ensuring it is secure and leak-free.
Bleed the brake lines to remove any air from the system.

5. Brake Rotor Inspection and Replacement (if necessary)

If rotors are warped or scored, remove the rotor from the hub.
Replace with new rotors as required, ensuring they are installed correctly and torqued to specifications.

6. Reassemble and Test

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the specified torque settings.
Test the brakes to ensure proper function before returning to normal driving.
