Funny noise/feeling from Brakes?

Hi Guys,

Don't know if anybody else has similar experience, but sometimes when pressing on the brake pedal of the FJ, it makes a funny noise (like the sound of a CD changing) and makes a quick vibration from the pedal. Doesn't affect braking at all. Anybody else have this issue?

This is not an issue that requires attention, it's a normal effect of the type of braking system on the FJ.

The braking system is highly pressurized, to allow the system's ATRAC and the other traction enhancement systems to work properly. There is an electric pump mounted next to the brake master cylinder that pressurizes the unit when you first start it or sometimes after/during a brake application. It will activate whenever the pressure in the reservoir drops below a certain level.

Pump you brakes a few times with the engine idling and you will hear it activating to re-pressurize after a couple presses of your brake pedal.

Thanks again Rover, I hadn't thought twice about it, but my fiance asked (she has an 08 Camry) and said she had never felt/heard anything like that before. Glad to have the answer!

Well thanks for the information. I never noticed any of the small noises, but now that you pointed them out I'm sure they'll drive me crazy!
