Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the negative battery terminal for safety.

2. Inspect and Replace Brake Pads

Tools Required: Jack and jack stands, socket set, torque wrench.
Remove the wheel to access the brake assembly.
Inspect the brake pads for thickness; replace if worn below 3mm.
Remove the caliper using a socket wrench and hang it securely without stressing the brake line.
Replace pads with new ones, ensuring they are seated properly.
Reattach the caliper and torque to manufacturer specifications.

3. Inspect and Resurface/Replace Brake Rotors

Tools Required: Brake rotor tool (if resurfacing), socket set, torque wrench.
Check rotors for warping using a runout gauge or by feel.
If warped, either resurface the rotors or replace them with new ones.
If resurfacing, follow manufacturer’s specifications for minimum thickness.
Reinstall rotors and torque to specifications.

4. Check Brake Calipers

Inspect calipers for any signs of sticking or malfunction.
If calipers are sticking, they may need to be rebuilt or replaced.
Ensure the brake caliper slides move freely; apply brake grease as needed.

5. Brake Fluid Check and Replacement

Tools Required: Brake fluid tester, brake bleeder kit.
Check brake fluid level in the reservoir; top off with the manufacturer-approved fluid if low.
Test fluid for moisture content. Replace if contaminated.
Bleed the brake lines to remove any air pockets using a brake bleeder kit.
