Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is turned off.
Wear safety glasses and gloves for protection.

2. Inspect and Replace Brake Pads

Tools Required: Socket set, brake pad spreader, torque wrench
Remove the wheel to access the brake assembly.
Remove the caliper bolts using a socket set.
Carefully slide the caliper off the rotor and support it (do not hang it by the brake line).
Use a brake pad spreader to compress the caliper piston.
Remove the old brake pads and inspect the rotors for grooves or warping.
Install new brake pads and reattach the caliper, ensuring bolts are torqued to manufacturer specifications.

3. Bleed Brake Lines

Tools Required: Brake bleeder kit, clear tubing, wrench
Begin with the brake furthest from the master cylinder (usually the right rear).
Attach clear tubing to the bleeder valve and submerge the other end in brake fluid.
Have an assistant pump the brake pedal several times, then hold it down.
Open the bleeder valve to release air and fluid, then close it before the pedal is released.
Repeat until no air bubbles are visible in the tubing.
Move to the next wheel and repeat until all brakes are bled.

4. Check and Replace Brake Fluid

Tools Required: Brake fluid (DOT 3 or DOT 4), funnel
If fluid is low or contaminated, remove the old fluid by siphoning it from the master cylinder.
Clean the reservoir and refill with new brake fluid.
Ensure the fluid level is at the recommended mark.
