Problems:
Brake fluid leaks
Hydraulic brake systems are prone to brake fluid leaks, which can lead to reduced braking efficiency and potentially brake failure.
Brake pad wear
Over time, brake pads wear down and need to be replaced to ensure proper braking performance.
Master cylinder failure
The master cylinder can fail or develop issues, leading to a loss of hydraulic pressure and ineffective braking.
Brake line corrosion
Brake lines can corrode over time, especially in areas with harsh weather conditions, leading to leaks and braking issues.
Brake caliper problems
Brake calipers can seize or fail, causing uneven braking and reduced performance.
Brake rotor warping
Excessive heat and wear can cause brake rotors to warp, leading to vibrations and reduced braking efficiency.
Abs sensor failure
The Anti-lock Braking System (ABS) sensors can fail, leading to ABS malfunctions and potentially unsafe driving conditions.
Vibration during braking
Warped rotors or uneven brake pads can cause vibrations when the brakes are applied.
Soft brake pedal
Air in the brake lines or a failing master cylinder can cause a soft or spongy brake pedal feel.
Brake warning light
The brake warning light on the dashboard can indicate various issues within the brake system, including low brake fluid, worn pads, or ABS problems.

Problems:
Brake fluid leaks
Hydraulic brake systems can suffer from leaks in the brake lines, master cylinder, or calipers, leading to reduced braking efficiency.
Brake fade
Prolonged usage, especially in hilly or mountainous terrain, can lead to brake fade due to overheating of the brake components.
Warped brake rotors
Continuous heavy braking can cause the rotors to warp, resulting in vibrations or pulsations when braking.
Worn brake pads
Over time, the brake pads wear out and need to be replaced to maintain effective braking performance.
Engine misfire
The V-shaped, 6-cylinder configuration can experience misfires due to issues with spark plugs, ignition coils, or fuel injectors.
Coolant leaks
The engine's 90-degree V-configuration can sometimes lead to coolant leaks from the intake manifold gaskets.
Oil consumption
The WRN LU3 engine may consume more oil than expected, necessitating frequent checks and top-ups.
Timing chain issues
Over time, the timing chain can stretch or wear out, leading to issues with engine timing and performance.
Intake manifold gasket failure
The intake manifold gasket on this engine can fail, leading to coolant leaks and potential engine overheating.
Fuel pump failure
The fuel pump may fail, causing issues with fuel delivery to the engine and resulting in poor performance or stalling.
Transmission problems
The 2004 Chevrolet Blazer is known to have issues with the automatic transmission, including slipping gears and hard shifts.
Electrical issues
Problems with the vehicle's electrical system can lead to malfunctioning gauges, lights, and other electronic components.
Rust and corrosion
Older models like the 2004 Blazer can suffer from rust and corrosion, particularly in the brake lines and undercarriage.
