Inspect brake pads for uneven wear or damage.
2
Check brake rotors for warping or scoring using a dial indicator.
3
Measure rotor thickness to ensure it meets manufacturer specifications.
4
Examine brake calipers for proper functioning and fluid leaks.
5

Solution

1. Preparation

Gather tools and parts required.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal for safety.

2. Remove Wheel

Use a jack to lift the front or rear of the vehicle, depending on which brakes are being serviced.
Secure with jack stands.
Remove lug nuts using a socket wrench and take off the wheel.

3. Inspect and Replace Brake Pads

Remove the brake caliper by unscrewing the caliper bolts using a socket set.
Slide the caliper off the rotor and support it without stressing the brake line.
Remove the old brake pads from the caliper bracket.
Install new brake pads, ensuring they are properly seated.

4. Inspect and Resurface or Replace Rotors

Remove the rotor by removing the retaining screws if applicable.
Use a dial indicator to check for warping; if warping exceeds manufacturer specifications, resurface or replace the rotor.
If resurfacing, clean the rotor thoroughly and ensure it is within acceptable thickness limits.
Reinstall the rotor onto the hub.

5. Reassemble Components

Reattach the brake caliper over the new pads and rotor.
Tighten the caliper bolts to the manufacturer’s torque specifications.
Reinstall the wheel and lug nuts, tightening them in a crisscross pattern to ensure even pressure.
Lower the vehicle and reconnect the negative battery terminal.
