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 handling components.

Symptoms

•Vibration felt through the steering wheel when braking
•Pulsating brake pedal during braking
•Uneven wear on brake pads or rotors
•Noise coming from brakes, such as grinding or squeaking
•Vehicle pulling to one side when braking

Diagnostic Steps

1
Inspect brake rotors for warping or uneven wear using a dial indicator.
2
Check brake pads for thickness and even wear pattern.
3
Examine wheel bearings for play or damage by shaking the wheel side to side.
4
Verify tire condition and balance; check for flat spots or uneven wear.
5
Inspect suspension components (e.g., control arms, bushings) for wear or damage.

Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Use wheel chocks to prevent the vehicle from rolling.

2. Remove Wheel

Loosen lug nuts using a socket and wrench.
Jack up the vehicle and place it securely on jack stands.
Remove the wheel to access the brake components.

3. Inspect and Replace Brake Rotors

Use a dial indicator to measure rotor runout; if warping is found, replace rotors.
If rotors are within specifications, clean them with brake cleaner to remove contaminants.
Install new rotors, ensuring to torque the bolts to manufacturer specifications (typically around 70-90 ft-lbs).

4. Inspect and Replace Brake Pads

Remove the brake caliper by unbolting it and hanging it securely (do not let it dangle by the brake line).
Inspect the brake pads for wear; replace if they are below the minimum thickness (usually around 3 mm).
Apply a thin layer of brake grease to the back of new pads to prevent noise.
Reinstall the brake caliper and torque bolts to specifications (usually around 25-35 ft-lbs).

5. Reassemble and Test

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and finish tightening the lug nuts in a star pattern to ensure even pressure.
Test the brakes by pumping the brake pedal before driving.
