Park Brake Light

[cdescher]

On my '04, which I recently purchased, I have an intermittent problem with the park brake warning light coming on. For the first five minutes or so, after starting the engine, the light stays on after the brake is release. Then it will come back on pretty regularly, especially if I turn the truck to the right, but I haven't found anything that will consistently turn it back off. Any ideas?

The service manual says

"1 - Brake fluid level"

"2 - Hydraulic brake booster power supply system (Faulty)"

Actually I am having the worst - (ABS) light, ((!)) light, and a buzzer sound - most likely case #2. Anyone has any idea on how much it will take to fix it?

Thanks....

Add fluid to the reservoir. Even though it appears to have plenty in it, it needs to be full enough to not trigger the sensor. Initially when getting "low" the light will come on while acceleration or when driving on an incline. This happens on all my Toyotas. Once I get the reservoir full - usually a little above the "full" line, the light quits coming on.

For mqz502, I do not recall having the buzzer sound. I would still start with #1, then move to #2.
