Brake fluid leaking no visable signs - Cars & Trucks

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.

you might need a new master cylinder

If there are no visible leaks check your master cylinders behind the tires might be why there's no brake pressure or are we talkin about the emergency brake pedal?

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.

Hi:
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

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.

check all brake lines , and connections, may have to pull master forward to make sure its not leaking into booster from the back .good luck.

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.

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.)

hi get it prussure tested if you are correct in saying there is no sign of a leak or signs of water in the exhaust then you will have a leak and what is happening is it is evaporating as it leaks hence on sign of leak usually theseleaks are found where hose are near something hot example exhaust manifold the pressure tester will make the leak visable yates210456
