Need to know the location. Under bonnet/hood or back of the car or on brakes themselves? Check all the pipeline, there might be minimal hole where fluid spreads out like an oil. Could be reservoir leak or some gasket broken on brakes. Or some bleeding screw is loose or pipe connection screw.

It could possibly be a leaking wheel cyl in one of the rear drums. With all of the dust soaking up the fluid it is sometimes hard to notice the leak.

My boyfriends Toyota Tundra is leaking brake fluid. Sometimes a horrible white smoke billows out of the exhaust pipe just after starting up the truck. It quits after a few minutes. Where do you think the...

The white smoke has nothing to do with the brake fluid loss. Look around the brake master cylinder, brake lines and joiners and brakes for signs of moisture. They should all be clean and dry any build up of dirt could be a hydraulic leak. The white smoke is more likely from warn valve guides.

How to fix intermittent brake pressure loss

If you intermittently have your brake pedal go to the floor, you need to give this immediate attention, as this is a safety concern. First, check the fluid level in your brake master cylinder. If it is full, you most likely that you have a failed brake master cylinder, if there are no obvious leaks or fluid loss

No brake fluid in resivoue no leak visable

As the brake pads/shoes wear. Fluid level will decrease in the master cylinder resovoir. If the master cylinder ran empty you will need to refill with appropriate brake fluid (should say DOT 3 on cap) and bleed air from the system.

E Brake light is on

based on the very limited amount of information given, in general when the brake light comes on it could be for a variety of reasons but it is always best to start simple. Open the hood and somewhere towards the back you should see a plastic container that houses the brake fluid. It should have a warning on top about using only DOT approved brake fluid or some similar warning. Check the level as indicated on the outside of the brake fluid tank. If it is low add to the proper level. The fluid level will be low because you either have (A) a leak or (B) your brakes are going to need to be changed soon. Adding fluid (should) make the light go off but you should have the brakes inspected ASAP and most places do it for free.

Brake Light On (in dash)

look inside all wheels and under car for break fluid, you may have a wheel cyl.leaking or a busted break line, or the resavor may have got low enought to trigger the light. if no visable signs of fluid leaks, take it to a local auto parts store and have them hook there scanner up and turn your break light off for you (unless you can disconnect battery to erase the break light i don't know). you may have just triggered the switch for (to low fluid.)
