Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Use wheel chocks to secure the vehicle.
Wear safety goggles and gloves.

2. Check Brake Fluid Level

Open the hood and locate the brake master cylinder.
Inspect the fluid level; if low, top up with the recommended brake fluid (DOT 3 or DOT 4 as specified in the owner’s manual).

3. Bleed the Brake System

Tools Required: Brake bleeder kit or clear tube, container for old fluid.
Start with the wheel furthest from the master cylinder (right rear).
1. Attach the clear tube to the bleeder valve on the brake caliper.
2. Have an assistant pump the brake pedal several times and hold it down.
3. Open the bleeder valve to release fluid and air; close it before the assistant releases the pedal.
4. Repeat until fluid flows without bubbles, then tighten the bleeder valve.
5. Move to the next wheel (left rear, right front, left front) and repeat the process.
Monitor brake fluid level in the master cylinder during bleeding and top up as necessary.

4. Inspect Brake Pads and Calipers

Remove the wheel to access the brake assembly.
Check brake pads for proper installation and ensure they are not excessively worn.
Inspect caliper function by ensuring they slide freely and are not seized.
If calipers are damaged, replace them as necessary.
