Most common problems:

Brake fluid leaks

Hydraulic brake systems can develop leaks in the brake lines, master cylinder, or calipers, leading to a loss of braking power.

Brake master cylinder failure

The master cylinder, which generates the hydraulic pressure needed for braking, can wear out or fail, causing a soft or spongy brake pedal.

Brake pad and rotor wear

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

Faulty brake booster

The brake booster can fail, leading to increased pedal effort and reduced braking efficiency.

Abs sensor issues

The Anti-lock Braking System (ABS) sensors can malfunction, causing the ABS warning light to illuminate and potentially affecting braking performance.

Vacuum leaks

In an in-line 6-cylinder engine, vacuum leaks can occur, affecting engine performance and braking if the brake booster is vacuum-operated.

Overheating issues

The 2004 Jeep Wrangler with an in-line 6-cylinder engine can experience overheating problems, often due to a faulty thermostat, water pump, or radiator.

Head gasket failure

This engine configuration may suffer from head gasket issues, which can lead to coolant leaks and engine overheating.

Crankshaft position sensor failure

A common problem with the in-line 6-cylinder engine is crankshaft position sensor failure, leading to engine stalling or failure to start.

Fuel injector problems

Fuel injectors can become clogged or fail, causing rough idling, misfires, and poor fuel economy.

Exhaust manifold cracks

The exhaust manifold on the 2004 Jeep Wrangler's in-line 6-cylinder engine can crack, leading to exhaust leaks and increased engine noise.
