1Gen-TundraGeneral discussion forum for the 2000 to 2006 Toyota Tundra.
This is a discussion thread titled "Brake Light Coming On?! Help?!", within the 1Gen-Tundra forum, part of the Truck Forums category.
Okay, here is the deal....whenever I have to brake with moderate force the brake light on the dashboard comes on!?! This is the one that indicates that your parking brake is on. The parking brake is released and does not have any slop in it to make the light come on..
Any ideas would be helpful...thanks.

Check brake fluid - the light also comes on when fluid is low.

Yes, your brake fluid is low. As your pads and shoes wear down more fluid is required in each slave cylinder thus resulting in a low brake fluid resivoir. Also when you push on the brakes hard you are forcing more fluid to the slaves and away from the resivoir and low level switch.
Okay, this may sound stupid....but....can I just add more fluid, or should I just take it to a shop? I have done a lot of mechanic work on trucks over the years, but I have never mess with the brake system.
PS. Krodad - It looks like we have a football game between our two schools this weekend! KSU vs. ISU...

Hello HockeyFreak,
Yes, you can add fluid, make sure that you add the proper fluid type.
However, there is no such thing as a "Brake Fluid Monster" , if you need to add a lot of fluid or add fluid frequently, chances are you have a leak somewhere in your brake system .
Good luck
Edited for clarification.

Buy a small bottle at any auto parts store. Add a few ounces to the reservoir. The reservoir has the full level marked.

HF,
Yes you can just add more fliud. But this may be an indicator that your pads are getting a little worn. Do a visual check of them, too.

As brake material wears from the pads and shoes the caliper pistons and wheel cylinder seals move outward and additional brake fluid is used to fill the expanded volume behind them.

If a combo of all these whizz bangs met their claims you'd have to syphon gas out of your tank every second day and sell the excess horsepower on the third????

HockeyFreak...two pretty closely matched teams if you look at the stats...almost identical rushing, passing, points, etc. We just kicked the crap out of A&M and we're on a roll and we're home. Good luck to the 'Cats but I gotta hope the Clones can keep it going...my wife promised me that If the Clones go to a bowl, I can go to.

Well, I may just take it in to my mechanic and have them check the brake system over just to make sure everything is fine.
After four years, it is past time to complete flush and renew the brake fluid. Brake fluid absorbs moisture from the atmosphere. The water in the brake fluid lowers the boiling point of the fluid. Very heavy braking can generate enough heat to cause the brake fluid to flash to vapor. Your brake pedal goes to the floor and you have no braking. I've know this to happen to a friend, and read about it happening in a nearby hilly state park...a death resulted. http://www.raceshopper.com/brake_fluid_faq.shtml
I'd suggest that you have the shop do a brake fluid flush and replacement even if the brakes are good. My choice for front brakes would be Wagner Thermoquiet if you don't go to a high performance pad like Hawk or Performance Friction. http://www.federal-mogul.com/cda/con...6_7293,00.html

What he said! I highly doubt the system is leaking, cause you would have noticed drips on your nice, new concrete garage floor. If you take it to the mechanic, I'll bet good money that he tells you it's almost time for new brakes all the way around. Dumping in more brake fluid will keep the light from coming on, but when you do eventually add the new pads & shoes your going to have to siphon some of the brake fluid out of the resevoir so you don't have a major mess when you push the pistons back.
