It could just be that when you push the brakes the fluid level goes below the proper level. add fluid and see if stops.
WHICH fluid.
check fluid level
On a Ford Ranger , DOT ( 3 ) brake fluid
Regular DOT3 brake fluid
DOT3
Dextron 5
The best way to tell when you need brakes is by squeaking, when the brakes are rubbing against the metal, when your brake pedal goes all the way to the floor and when you are running out of break fluid.
No you can not. If you do it can ruin your quad brakes and possibly your engine. If you do and something goes wrong you could have to spend a lot of money to get it fixed if that.
hydraulic brakes work on hydraulic fluid the system is filled with fluid, all air is bled out of the system so only fluid remains thru valves and other components the fluid is displaced when when the breake pedal is pressed on each wheel at the brakes are some moving parts ,on drum brakes these are brake shoes and cylanders on disk brakes these are brake pads and calipers when the fluid is displaced thru use of the pedal these parts are pushed out by the fluid that ahas no where else forcing the pads or shoes against the brake disk or drum when pedal is released the fluid goes back to reservoir releasing pressure on parts at wheel which releases brakes
ford type f or mercon fluid [you can also use dextronII but I wouldn't recommend it!!
MERCON V It's Ford's transmission fluid.
