Acceleration Noice-1999lexus Es300 Model

[ericsun]

Hello all,

Please tell me something about the short-minor noice problem,when accelerated it slowly:

When the green light was on, I released my brake pad and then started to accelerate SLOWLY. The short-minor noice happened right after I started to slowly accelerate,then short noice disappeared immediately. The noice came from somewhere in the front. I don't know if it's related to acceleration system.

Thanks for your input.

eric, you give no details on what the noise sounded like.

1. was it a vibration, clanking, ringing, pinging, plastic sound, metal sound?

2. does it do it every time you accelerate, does it do it when you accelerate slow or fast or both?

3. was it a constant sound for its short duration, was it high pitchec, low pitched, sound like air, sound like something scraping?

do you follow me?

to ask what a noise only you heard was is kind of hard to answer.

more details and we might be able to help.

Hello Steve,

It is not metal sound,but sounds like plastic scratch.

The noice sounds like the pronounced of ""clock", and it was NOT a constant sound for its short duration. It's a one-time-only and short noice pulse right on accelerator was pressed,then it disappeared.

This happened ONLY while accelerated slowly (not fast accelerated), but not always happened while accelerated slowly.

Two weeks ago, I had my car for brake service (replaced front brake pads,replaced brake fluid,Rotors and drums machined, tire rotation). This noice problem was never happened until I did brake service.

I'm not sure the brake service is related to the problem.

Thanks,

Eric

Hope this help.

When you push for brake, pads comes inner to rotter after you release brake, that spring return brake pads to original location.
