•Always ensure the vehicle is securely lifted and supported before working underneath.
•Allow brake components to cool if previously used to prevent burns.

Symptoms

•Steering wheel shakes during braking
•Vehicle pulls to one side when braking
•Brake pedal feels pulsating or spongy
•Increased stopping distance
•Unusual noise (grinding or squeaking) when brakes are applied

Diagnostic Steps

1
Inspect brake pads for wear and thickness using a caliper gauge.
2
Check brake rotors for warping by measuring runout with a dial indicator.
3
Examine brake calipers for proper operation and signs of sticking.
4
Inspect suspension components (such as control arms and bushings) for wear or damage.
5
Verify tire balance and condition, checking for uneven wear or damage.
6
Perform a road test to replicate the shaking and note the speed and conditions.

Solution

1. Preparation

Gather tools and parts needed for the repair.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety.

2. Remove Wheel Assembly

Using a socket set, loosen the lug nuts and lift the vehicle with a jack.
Remove the wheel to access the braking components.
Tools Required: Jack, jack stands, lug wrench.

3. Inspect and Replace Brake Pads

Remove the caliper by unbolting it from the bracket.
Slide out the old brake pads and inspect for wear.
If worn, install new brake pads, ensuring they are seated properly.
Tools Required: Socket set, brake pad spreader.

4. Inspect and Resurface or Replace Rotors

Remove the rotor from the hub assembly.
Check for warping using a dial indicator; if warped beyond specifications, resurface or replace the rotor.
Install the rotor back onto the hub.
Tools Required: Dial indicator, rotor puller (if needed).

5. Reassemble Components

Reattach the brake caliper over the new pads.
Tighten caliper bolts to the manufacturer’s torque specifications (typically around 25-35 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

6. Final Checks

Lower the vehicle and torque the lug nuts to the manufacturer's specifications (typically around 76-83 ft-lbs).
Reconnect the battery terminal.
Test the brake system by pressing the pedal several times before driving.
