Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Always disconnect the battery before working on electronic components.
•Allow the brake system to cool down before working on it to avoid burns.

Symptoms

•Vehicle shakes or vibrates when brakes are applied
•Steering wheel may also vibrate during braking
•Increased stopping distance or brake pedal pulsation
•Uneven tire wear may be observed
•Possible noise from the brake system (squeaking or grinding)

Diagnostic Steps

1
Inspect brake pads for wear and thickness using a visual check.
2
Check brake rotors for warping or uneven surfaces by measuring with a dial gauge or straight edge.
3
Examine brake calipers for proper operation and signs of sticking or seizing.
4
Inspect wheel lug nuts for proper torque and ensure they are not loose.
5
Perform a visual inspection of the suspension components for wear or damage.
6
Check tire balance and alignment to rule out issues unrelated to the braking system.

Solution

Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety gloves and goggles.

2. Remove Wheel

Tools Required: Jack, jack stands, lug wrench.
Sub-steps:
1. Loosen the lug nuts slightly while the wheel is still on the ground.
2. Lift the vehicle using a jack and secure it with jack stands.
3. Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Tools Required: Socket set, torque wrench, brake cleaner.
Sub-steps:
1. Remove the caliper by unbolting it from the bracket.
2. Slide the caliper off and suspend it without straining the brake line.
3. Remove old brake pads from the caliper bracket.
4. Clean the caliper bracket and install new brake pads.
5. Reinstall the caliper and torque the bolts to manufacturer specifications.

4. Inspect and Replace Brake Rotors (if necessary)

Tools Required: Rotor puller, socket set, torque wrench.
Sub-steps:
1. Remove the caliper bracket to access the rotor.
2. Check rotor thickness and surface for warping using a micrometer.
3. If warped, remove the old rotor and replace with a new one.
4. Torque the new rotor to manufacturer specifications.

5. Reassemble and Test

Tools Required: Same as above.
Sub-steps:
1. Reattach the caliper bracket and caliper, ensuring all bolts are torqued correctly.
2. Reinstall the wheel and hand-tighten the lug nuts.
3. Lower the vehicle and tighten the lug nuts to manufacturer specifications.
