Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery for safety.

2. Brake Fluid Inspection

Tools Required: Brake fluid tester, clean rag.
Check the brake fluid level in the master cylinder reservoir.
If low, top off with manufacturer-recommended brake fluid (DOT 3 or DOT 4).
Inspect the fluid for contamination (discoloration or particles).

3. Brake Pad Replacement

Tools Required: Socket set, torque wrench, brake caliper tool, c-clamp.
Remove the wheel to access the brake caliper.
Use a socket to remove caliper bolts, and carefully slide the caliper off the rotor.
Remove the old brake pads from the caliper bracket.
Compress the caliper piston using a brake caliper tool or c-clamp to allow for new pads.
Install new brake pads, ensuring proper orientation and alignment.
Reinstall the caliper and torque bolts to manufacturer specifications (usually around 25-30 ft-lbs).

4. Brake Rotor Inspection/Replacement

Tools Required: Rotor puller (if necessary), torque wrench.
Check rotors for warping or excessive wear.
If replacement is needed, remove the rotor by loosening the retaining screws and sliding it off the hub.
Install new rotors, ensuring they are free of grease and debris.
Torque any retaining screws to the specified value (typically 10-15 ft-lbs).

5. Brake Line Inspection/Repair

Tools Required: Wrench set, brake line flare tool.
Inspect brake lines for corrosion or damage.
Replace any damaged lines using the appropriate flare and fittings.
Ensure all connections are tight and free of leaks.
