Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the negative battery terminal to avoid electrical shorts during repairs.

2. Inspect and Replace Brake Pads

Remove the Wheel
- Use a jack to lift the vehicle and secure it on jack stands.
- Remove the wheel using a socket set.
Inspect Brake Pads
- Check the thickness of the brake pads. If less than 3mm, replace them.
- Look for uneven wear patterns.
Replace Brake Pads (if necessary)
- Remove the caliper bolts with a socket wrench.
- Carefully slide the caliper off the rotor.
- Remove the old pads and insert new pads into the caliper bracket.
- Reinstall the caliper and tighten bolts to manufacturer specifications (typically around 25-30 ft-lbs).

3. Inspect and Replace Brake Rotors (if warped)

Remove the Caliper and Rotor
- Follow steps above to remove the caliper.
- Remove any retaining screws and slide the rotor off the hub.
Inspect Rotors
- Use a straightedge to check for warping or uneven surfaces.
- If warped, replace with new rotors.
Install New Rotors
- Clean the new rotor with brake cleaner to remove any protective coating.
- Install the new rotor and secure it with screws.
Reinstall Caliper
- Reattach the caliper and tighten bolts to specification.

4. Bleed Brake System

Reattach Brake Lines
- If calipers were disconnected, ensure all lines are securely fastened.
Bleed Brakes
- Start at the wheel farthest from the master cylinder; use a brake bleeder tool or have an assistant pump the brake pedal while you open and close the bleeder valve.
- Ensure there are no air bubbles in the fluid.
