Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Always disconnect the battery before working on the braking system.
•Allow the brakes to cool before working, as they can become very hot during use.

Symptoms

•Brake pedal pulsates during braking
•Uneven braking force felt through the pedal
•Vibration in the steering wheel while braking
•Increased stopping distance
•Noise coming from the brakes when applied

Diagnostic Steps

1
Inspect brake rotors for warping or uneven wear using a dial indicator.
2
Check brake pads for wear and ensure they are not glazed or unevenly worn.
3
Examine brake calipers for proper operation and ensure they are not sticking.
4
Inspect wheel bearings for play or wear that could contribute to braking issues.
5
Check brake fluid level and condition, ensuring it is clean and free of moisture.

Solution

Solution

1. Preparation

Gather tools and parts needed: socket set, torque wrench, brake cleaner, dial indicator, new rotors, new brake pads.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the negative battery terminal for safety.

2. Remove Wheel and Brake Components

Use a socket set to remove the wheel lug nuts and take off the front wheels.
Remove the brake caliper by unscrewing the caliper bolts with a socket wrench.
Support the caliper with a bungee cord or hang it to avoid straining the brake line.

3. Inspect and Replace Brake Rotors

Measure the thickness of the rotors with a caliper. If they are below the minimum thickness specification, replace them.
If warped, remove the old rotors by unscrewing the retaining screws (if applicable) and pulling them off the hub.
Clean the hub surface with brake cleaner to ensure proper seating of the new rotors.
Install new rotors, aligning them properly and securing with screws if required.

4. Inspect and Replace Brake Pads

Remove the old brake pads from the caliper bracket. Note the orientation for reinstallation.
Check the caliper slides for lubrication; apply brake grease if necessary.
Install new brake pads in the caliper bracket, ensuring they are seated correctly.

5. Reassemble Braking Components

Reattach the brake caliper over the new pads and rotor, ensuring it is properly aligned.
Tighten the caliper bolts to the manufacturer's torque specifications (typically around 25-30 Nm).
Reinstall the wheel and lug nuts, tightening them in a star pattern to the specified torque (around 100 Nm).

6. Final Checks

Reconnect the negative battery terminal.
Pump the brake pedal several times to seat the pads against the rotors.
Check brake fluid level and top off if necessary.
