⚠️ Safety Warnings

Important safety information - read before proceeding

•Always disconnect the battery when working on brake components to prevent accidental deployment of electrical systems.
•Ensure the vehicle is securely lifted and supported before working underneath it.

Symptoms

•Pulsating brake pedal when braking
•Vibration in the steering wheel during braking
•Uneven wear patterns on brake pads
•Increased stopping distance
•Noise (e.g., grinding or squeaking) when brakes are applied

Diagnostic Steps

1
Inspect brake rotors visually for warping or uneven surfaces.
2
Check brake pads for wear and proper thickness.
3
Measure rotor thickness with a micrometer to ensure they meet manufacturer specifications.
4
Examine brake calipers for proper operation and potential sticking.
5
Inspect wheel bearings for play or wear that could contribute to vibration.

Solution

Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety glasses and gloves.

2. Remove Wheel

Sub-steps:
1. Loosen lug nuts slightly while the vehicle is still on the ground.
2. Use a jack to lift the vehicle and secure it with jack stands.
3. Remove the lug nuts completely and take off the wheel.

3. Inspect and Remove Brake Components

Sub-steps:
1. Remove the caliper bolts using a socket set.
2. Carefully slide the caliper off the rotor and suspend it using a bungee cord (do not let it hang by the brake line).
3. Remove the brake pads from the caliper bracket.
4. If necessary, remove the caliper bracket by unscrewing its mounting bolts.

4. Measure and Replace Rotors

Sub-steps:
1. Use a micrometer to measure the thickness of the rotor and check for warping.
2. If the rotors are below specification or warped, remove them by unscrewing the rotor retaining screws (if present) and pulling the rotor off the hub.
3. Install new rotors, ensuring they are clean and free of oils or debris.

5. Install New Brake Pads

Sub-steps:
1. Apply brake grease to the back of the new brake pads where they contact the caliper.
2. Install the new brake pads into the caliper bracket.
3. Reattach the caliper over the brake pads and secure it with the caliper bolts, tightening to manufacturer specifications.

6. Reassemble and Test

Sub-steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Lower the vehicle from the jack stands and tighten the lug nuts to proper torque specifications.
3. Pump the brake pedal a few times to seat the brake pads.
