2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect the battery before working on electrical components.
•Always ensure the vehicle is securely supported on jack stands before working underneath it.

Symptoms

•Steering wheel shakes during braking
•Vehicle pulls to one side when braking
•Abnormal noise from brake components (squeaking or grinding)
•Vibration felt in the brake pedal
•Brake warning light may illuminate

Diagnostic Steps

1
Inspect brake pads for uneven wear or damage.
2
Check brake rotors for warping or scoring using a runout gauge.
3
Examine brake calipers for proper operation and signs of sticking.
4
Assess suspension components for wear or damage, particularly control arms and bushings.
5
Inspect wheel alignment and balance to rule out related issues.

Solution

Diagnostic Steps

1
Inspect brake pads for uneven wear or damage.
2
Check brake rotors for warping or scoring using a runout gauge.
3
Examine brake calipers for proper operation and signs of sticking.
4
Assess suspension components for wear or damage, particularly control arms and bushings.
5
Inspect wheel alignment and balance to rule out related issues.

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Disconnect the battery to avoid any electrical issues while working on the brakes.

2. Remove Wheel

Loosen the lug nuts slightly while the vehicle is on the ground.
Raise the vehicle with a jack and secure it with jack stands.
Fully remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Remove the brake caliper bolts using a socket set.
Carefully slide the caliper off the rotor and support it with a bungee cord (do not let it hang by the brake line).
Remove the old brake pads and inspect them for wear.
If necessary, replace the brake pads with new ones, ensuring they are properly aligned and seated.

4. Inspect and Resurface/Replace Brake Rotors

Check the rotors for warping using a runout gauge: if the rotor exceeds manufacturer specifications, it should be resurfaced or replaced.
Clean the rotor surface with brake cleaner to remove any debris or dust before reassembly.

5. Reassemble Components

Reattach the caliper over the new brake pads and torque the caliper bolts to manufacturer specifications (typically around 20-30 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and fully torque the lug nuts to manufacturer specifications (typically around 70-80 ft-lbs).

6. Final Checks

Reconnect the battery and perform a brake function check.
Test brake operation at low speeds to ensure proper function without shaking.
