Brake System Problem Diagnosis

The braking system is a very important system in a vehicle. Damage to your system can cause an accident. However, there are many components in the system, and any damage to these components cause different problems for each other. Here are tips on how to make the initial diagnosis of your vehicle's brake problems on existing symptoms.

Brakes work, but the pedal needs to be pressed far;

Probability:

• Brake fluid level is low
• Water in the brake pipe
• Brake pads are nearly worn out

Brake paddle too hard.

Modern car brake paddle s assisted by brake booster, where it takes the vacuum pressure from the engine. So if you feel your brake paddle becomes hard;

Probability:

• Servo vacuum problem
• Faulty brakes
• Brake line blockage

No pressure on the brakes, the pedal close to the floor when pressed and the brake does not work;

Probability:

• The main pump is damaged / leaking.
• Leak in the brake line
• Leak in rear drum brake pump
• Air bubbles in the brake pipe

Brake feel 'spongy', to be pumped several times then works;

Probability:

• Air bubbles in the brake pipe

Car 'pulled' to a direction (left or right) when braking;

Probability:

• Brake calliper on one of the parts have been damaged or stuck

Brake pedal vibrates when braking;

Probability:

• Brake disc surface is not flat. Should be flattened surface (if still thick) or replaced directly.

Noisy brakes;

Probability:

• Brake pad is worn out or is too old and is already a hard material 
• Using artificial brake pads
