Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect the battery before working on electrical systems.
•Allow the vehicle to cool down before starting work on the brakes.

Symptoms

•Shaking or vibration felt in the steering wheel during braking
•Pulsation in the brake pedal
•Uneven brake pad wear
•Possible squeaking or grinding noises when braking
•Vehicle may pull to one side while braking

Diagnostic Steps

1
Inspect brake pads and rotors for wear and thickness using a visual inspection.
2
Check for any signs of brake rotor warping with a dial indicator for runout.
3
Examine suspension components (e.g., control arms, bushings) for wear or damage.
4
Inspect wheel alignment and balance for any discrepancies.
5
Scan vehicle for any error codes related to the braking system.

Solution

Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the 12V battery to avoid any electrical issues during repair.

2. Remove Wheel

Tools Required: Socket set, jack, jack stands
Loosen the lug nuts slightly while the vehicle is on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Completely remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Components

Check brake pads for wear; if less than 3mm thick, replace.
Inspect the brake rotors for warping; if they exceed 0.002 inches of runout, replace or resurface.
If replacing rotors, remove the caliper using the appropriate socket.
Remove the rotor by unscrewing any retaining screws and sliding it off the hub.
Install new rotors by reversing the removal process, ensuring all screws are torqued to manufacturer specifications.

4. Install New Brake Pads

Tools Required: Torque wrench
Remove old brake pads from the caliper bracket.
Compress the caliper piston using a brake caliper tool to allow space for new pads.
Install new brake pads in the caliper bracket.
Reattach the caliper over the new pads, ensuring it’s secured to the manufacturer’s torque specifications.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and tighten lug nuts to the manufacturer’s torque specifications.
Reconnect the 12V battery.
Perform a test drive to ensure the repair is successful and check for any remaining issues.
