Loss of Brake Assist

One of the primary issues owners face with the LOVOL brake booster is the loss of brake assist. This problem results in a significantly harder brake pedal. When the brake booster isn't functioning properly, it won't provide the necessary assistance to amplify the driver's braking force. The main cause of this issue could be a vacuum leak, which occurs when there’s a break in the sealed system.

To resolve this, inspect the vacuum lines connected to the brake booster for any cracks or disconnections. If you find damage, replace the vacuum line. Additionally, check the booster itself for any leaks or failure of internal components. If the booster is faulty, replacing the brake booster may be necessary to restore full braking function.

Brake Pedal Pulsation

If you experience pulsation in the brake pedal when you press down, it could indicate a problem with the LOVOL brake booster. This usually occurs due to contamination or wear affecting the brake fluid or the booster’s internal parts. If the brake pedal pulses under heavy braking, it may also be a sign of warped brake rotors.

A thorough inspection of the brake system is needed. Check the brake fluid for any signs of dirt or moisture and replace it if necessary. If you suspect damaged rotors, have them resurfaced or replaced according to the manufacturer's specifications. Ensuring your brakes are correctly maintained plays a crucial role in avoiding this issue.

Hissing Sound When Braking

A hissing sound when applying the brakes is another common issue with the LOVOL brake booster. This sound usually indicates that there's a vacuum leak somewhere within the brake booster system. A compromised seal or a crack in a vacuum line can lead to this issue. Over time, as the leak worsens, drivers may find that their brake pedal feels unresponsive.

You will get efficient and thoughtful service from Yuchung Power.

To fix this issue, start by listening for hissing sounds near the brake booster and vacuum lines. Inspect all connections for leaks and replace any damaged parts. If the hissing persists, it is advisable to consult a professional mechanic who can perform a more comprehensive diagnosis and repairs.

Braking Delay

A delay in braking response can be both frustrating and dangerous. This issue may stem from a malfunctioning LOVOL brake booster, which can fail to create enough vacuum pressure to assist in braking. The delay often increases the stopping distance, which could lead to accidents.

To address this problem, first, check for any visible damage to the booster and vacuum lines. If everything appears intact, a test of the brake booster’s operation may be required. This often involves measuring vacuum pressure. If the booster is not producing the required pressure, it should be replaced.

Check Engine Light Activation

Many vehicles equipped with a LOVOL brake booster may experience check engine lights illuminating due to issues with the braking system. This can be triggered by a failed brake booster sensor or other related systems not functioning correctly. Ignoring this warning could lead to more severe problems down the line.

To remedy this, use an OBD-II scanner to check for active trouble codes. If a code related to the brake booster appears, it’s essential to address it promptly by either resetting the system or replacing faulty components. Regular maintenance checks can help keep the braking system in optimal working condition and minimize these alerts.

If you are experiencing any of these issues with your LOVOL brake booster, it’s vital to seek professional assistance. Regular inspections can prevent major problems in the long run. Additionally, if you need further guidance or repairs, don't hesitate to contact us.
