Diagnostic Steps

Inspect brake pads for wear and damage.
2
Check brake rotors for scoring or uneven surfaces.
3
Examine brake calipers for proper function and any signs of sticking.
4
Inspect brake fluid level and condition.
5

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety gloves and goggles.

2. Lift the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheels to access the brake components.

3. Remove Brake Components

Brake Pads:
- Locate the caliper and remove the caliper bolts using a socket set.
- Slide the caliper off the rotor and support it without straining the brake line.
- Remove the old brake pads from the caliper bracket.
Brake Rotors:
- If necessary, remove the rotor by unscrewing any retaining screws and sliding it off the hub.

4. Inspect and Replace

Inspect the brake pads for wear; replace them if they are below the manufacturer's minimum thickness (typically 3mm).
Check the rotors for grooves or warping; replace if damaged.
Clean the caliper bracket and ensure it is free from debris.
Apply brake grease to the contact points of the new pads and caliper.

5. Reassemble

Install the new brake pads into the caliper bracket.
Slide the rotor back onto the hub (if removed).
Reinstall the caliper over the new pads and secure it with bolts to the specified torque (usually around 25-30 ft-lbs).
Repeat for the other side if necessary.

6. Lower the Vehicle

Remove the jack stands and lower the vehicle back to the ground.
