Diagnostic Steps

1
Inspect brake pads for wear and damage.
2
Check brake rotors for scoring or warping.

Examine the brake calipers for sticking or malfunction.
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 the ignition is off.
Tools Required: Jack and jack stands, lug wrench, socket set, brake cleaner, torque wrench.

2. Raise the Vehicle

Use the jack to lift the vehicle and secure it on jack stands.
Remove the wheel using a lug wrench to access the brake components.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket set.
Carefully slide the caliper off the rotor and suspend it using a bungee cord (do not let it hang by the brake line).
Inspect the brake pads for wear; if the friction material is less than 3mm thick, replace them.
Sub-steps:
- Remove the old brake pads from the caliper bracket.
- Clean the caliper bracket and apply brake grease to the contact points.
- Install new brake pads, ensuring they are seated properly.

4. Inspect and Replace Brake Rotors (if necessary)

Check the brake rotor for any scoring or damage.
If the rotor is below the minimum thickness or has significant damage, replace it.
Sub-steps:
- Remove the rotor by unscrewing any retaining screws and sliding it off the hub.
- Install the new rotor, ensuring it is properly aligned and seated.

5. Reassemble Braking Components

Reinstall the caliper over the new pads and rotor.
Torque the caliper bolts to the manufacturer's specifications (usually around 25-35 Nm).
Reattach the wheel and torque the lug nuts to the specified value (typically 100-120 Nm).

6. Lower the Vehicle and Test

Remove the jack stands and lower the vehicle.
Pump the brake pedal several times to ensure proper pad seating.
Check the brake fluid level; top off if necessary.
