Solution

1. Preparation

Gather all tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety gloves and goggles.

2. Replace Brake Pads

Tools Required:

Jack and jack stands
Lug wrench
Ratchet and socket set
Brake pad spreader tool
Torque wrench

Steps:

Lift the Vehicle:
- Use a jack to elevate the vehicle and secure it with jack stands.
Remove Wheel:
- Use the lug wrench to remove the wheel where brake pads will be replaced.
Remove Caliper:
- Use the ratchet and socket to remove the caliper mounting bolts. Carefully slide the caliper off the rotor and suspend it using a bungee cord to avoid straining the brake line.
Remove Old Brake Pads:
- Slide the old brake pads out of the caliper bracket.
Install New Brake Pads:
- Insert the new brake pads into the caliper bracket, ensuring they are properly seated.
Reinstall Caliper:
- Slide the caliper back over the new pads and secure it by tightening the mounting bolts to the manufacturer’s specified torque.
Reinstall Wheel:
- Place the wheel back on and hand-tighten the lug nuts.

3. Replace Brake Rotors (if necessary)

Tools Required:

Same as above, plus a rotor puller if rotors are stuck.

Steps:

Remove Caliper and Pads:
- Follow the same steps as for replacing the brake pads.
Remove Caliper Bracket:
- Remove the caliper bracket by unscrewing the bolts.
Remove Old Rotor:
- If applicable, gently tap the rotor with a hammer or use a rotor puller if it’s stuck.
Install New Rotor:
- Position the new rotor onto the hub, ensuring it fits snugly.
Reinstall Caliper Bracket and Caliper:
- Follow the steps to secure the caliper bracket and caliper as described above.

4. Bleed Brake System

After replacing components, bleed the brake system to remove air bubbles:

Locate Bleeder Valve:
- Find the bleeder valve on the brake caliper.
Attach Hose to Bleeder Valve:
- Place a clear hose over the bleeder valve and submerge the other end in a container with brake fluid.
Pump Brake Pedal:
- Have an assistant pump the brake pedal several times and hold it down.
Open Bleeder Valve:
- Open the bleeder valve to release air and fluid, then close it before the pedal is released.
Repeat Until No Air Bubbles:
- Continue this process until no air bubbles appear in the fluid.
