Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect battery before working on electrical systems.
•Allow engine to cool before opening any components.
•Use jack stands to support the vehicle securely.
•Ensure engine support before removing mounts.

Symptoms

•Vibrations felt through the steering wheel and seat
•Pulsating brake pedal when braking
•Increased noise from the engine bay
•Engine stalling or rough idling when at a stop
•Brake system warning light illuminated (if applicable)

Diagnostic Steps

1
Scan for error codes using an OBD-II scanner to check for any recorded trouble codes related to engine or brake systems.
2
Inspect brake components visually, including rotors, pads, and calipers, for wear or damage.
3
Check for warped brake rotors by measuring rotor thickness with a micrometer.
4
Test engine mounts for wear by visually inspecting for cracks or using the engine rocking method.
5
Examine the vacuum lines for leaks that could affect engine performance when idling.
6
Perform a road test to replicate the issue and note any changes in behavior during braking.

Solution
