How to check brake fliud

Just google out and download the user's manual
Check the fuses.
Also check the spray pipe under the hood!!

check the brake fluid level. the brake fluid can be low and comes on when stopping or going around curves. the brake fliud level sensor uses the same brake light as the parking brake. if the fliud is low check the pads and /or shoes for wear.

Open the engine hood.

There will be several fluid reservoirs under the bonnet. If the car / truck has power steering, one of them will hold about 150-300ml of fluid that should be a red color. If you put some on your hand it is very slippery.

The other reservoirs will hold water for the windscreen washer, and one connected to the radiator to hold coolant.

Check that the reservoir you intend to put the power steering fliud in is not connected to the radiator and does not contain water.

Take the cap off to check.

If you can't see in to the bottom, roll up some kitchen paper towel and feed that in until you get some fluid on it - red, you hope!

There will be marks (horizontal lines) on the side of the reservoir showing "Min" (minimum) and "Max" (maximum or full). Slowly pour in replavcement fliud until the tiop of the fluid is between the marks.. Put the cap back on, close the engine hood, drive for a short distance (2 km?) and check the levels again.

Top up the reservoir to just under "Max". Replace the cap.

Check the level after a short period of normal driving - a couple of weeks, If it is still going down a mechanic needs to check the power steering seals.

good luck.

As you didn't explain which fluid is low, here's a general explaination. There's always a cause for any fliud being low, the only fliuds that can fall below minimun levels are brake fliud [ as the brake pads or shoes wear it takes more fluid to push the surfaces together ] if not checked on a routine service, such as oil changes. The other is windshield washer fliud, which is lost with use.
Any other fliud loss isn't normal, and should be addressed.

That sounds like you may have broken a brake line except for the noise under the hood. Unless it is brake fluid squirting up, hitting the hood. Check the inside of all four tires and under the hood on the driver's side below the wind shield. My guess is you are going to find a big oily spot where all of your brake fluid has gone.

Normally when the brake pedal goes almos to the floor it is an indication of low brake fluid. Low brake fluid is an indication that front and/or rear brakes are wearing. As the brake pads wear down more brake fluid will be required in the wheel cylinders or calipers. Hint, the front brakes usually wear much faster than the rear due to the fact that the fronts due a much greater braking function that the rear. Check the front pads. Don't let them get down to the metal scraping metal stage before you change them out. This causes unnessary damage to the rotors. Look at your master cylinder on the firewall under the hood in front of the steering wheel. If the fluid level is belowhte "max" mark add fluid. Low fliud should also show as a red "brake" light on your dash, but not always.

Have you checked the clutch fluid level? I am referring to the clutch master cylinder which is usually mounted on the firewall near the master brake cylinder. If fluid level is low, clutch won't work. Hope it's that simple. Let me know.

Is the fliud a lite clear brown/tan (brake fliud) or is it a dark black colour (gear oil)? It sounds like you have a brake fluid leak. Check your steel line on the rear axle and then remove the wheel and drum and check the wheel cylinder. Top up your Master cylinder and bleed the brakes. You might find the light scrubbing noise gone.

if you can see a good amount of wet brake fluid between the brake master cylinder and the brake booster. and you have been adding fliud often,you could have a bad master cylinder. it has to be replaced not rebuilt. you however may have a far more common problem, a rusted through brake line.have someone pump the brake pedal, than look under the car for a brake fluid leak ,repair as needed. than bleed the brakes for a good hard brake pedal
good luck chris
