Most common problems:

Brake fluid leaks

Hydraulic brake systems rely on fluid to operate. Leaks can cause reduced braking efficiency or complete brake failure.

Brake pad wear

Over time, brake pads wear down and need to be replaced to maintain effective braking.

Master cylinder failure

The master cylinder is a critical component in a hydraulic brake system. Failure can lead to loss of braking power.

Warped brake rotors

High heat and heavy usage can warp rotors, causing vibrations and reduced braking efficiency.

Abs sensor issues

Faulty ABS sensors can lead to improper functioning of the anti-lock braking system.

Oil consumption

The LM7 V8 engine is known to sometimes consume more oil than expected, necessitating frequent oil checks and top-offs.

Intake manifold gasket leaks

The iron block can lead to gasket leaks, causing rough idling or coolant loss.

Fuel injector problems

Clogged or malfunctioning fuel injectors can lead to poor engine performance or misfires.

Knock sensor failure

The knock sensors on the LM7 can fail, leading to engine knocking and potential damage.

Timing chain wear

Over time, the timing chain can stretch and wear, leading to timing issues and poor engine performance.
