Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, brake cleaner, OBD-II scanner, torque wrench, socket set.
Ensure the vehicle is on a flat surface and engage the parking brake.
Disconnect the battery for safety.

2. Replace Brake Pads (if worn)

Lift the Vehicle: Use a jack to lift the front or rear of the vehicle (depending on which brakes are being serviced) and secure with jack stands.
Remove Wheel: Use a lug wrench to remove the lug nuts and take off the wheel.
Remove Caliper: Unbolt the caliper using the appropriate socket size. If necessary, support the caliper with a bungee cord or similar to avoid stress on the brake line.
Replace Brake Pads: Remove the old brake pads and replace them with new ones. Ensure they are properly seated in the caliper bracket.
Reinstall Caliper: Reattach the caliper over the new brake pads and torque the bolts to the manufacturer’s specifications (check service manual for exact torque values).
Reinstall Wheel: Put the wheel back on and hand-tighten the lug nuts.

3. Bleed Brake System (if spongy pedal)

Prepare Bleeding Kit: Assemble a brake bleeding kit or use a clear tube and container to catch old fluid.
Locate Bleeder Valve: Find the bleeder screw on the brake caliper.
Bleed Procedure: With an assistant, have them pump the brake pedal several times and hold it down. Open the bleeder valve to release air and fluid, then close it before they release the pedal. Repeat until the fluid runs clear.
Check Fluid Level: Continuously monitor and refill the brake fluid reservoir during bleeding to avoid introducing air into the system.
