Solution

1. Preparation

Gather tools and materials needed for the repair.
Ensure the vehicle is parked on a level surface and secure with wheel chocks.
Disconnect the battery to ensure safety during the repair.

2. Inspect and Replace Brake Pads

Tools Required: Socket set, brake pad spreader, torque wrench.
Remove the wheel using a socket set.
Remove the caliper bolts and carefully slide off the brake caliper.
Use a brake pad spreader to retract the caliper piston.
Remove the old brake pads and inspect the caliper for damage.
Install new brake pads ensuring they are correctly seated.
Reattach the caliper and secure it with bolts; torque to manufacturer specifications.

3. Inspect and Resurface/Replace Brake Rotors

Tools Required: Rotor measuring tool, brake cleaner, torque wrench.
Check rotor thickness and runout; if warped, decide whether to resurface or replace.
If resurfacing, clean the rotor surface with brake cleaner and use a brake lathe according to specifications.
If replacing, remove the old rotor and install the new one, ensuring proper fitment and torque the screws to the manufacturer's specifications.

4. Check Brake Fluid

Tools Required: Brake fluid tester or moisture meter.
Inspect the brake fluid reservoir; if low, top off with the recommended brake fluid type.
Test the brake fluid for moisture content; if high, consider a complete brake fluid flush.
