Leaks can occur anywhere in a brake system from the master cylinder in the engine compartment, to any of the lines and connector fittings along the lines, to the "slave" cylinders at each of the wheels.
The question of "what piece to replace" is the piece [or pieces] that are leaking or damaged.
Brake fluid is a special compound designed to hydraulically transfer force through tubing to be applied at a slave cylinder.
Leaking brake fluid, like most other liquids, will "wet" the area around, and due to gravity, the area below the leak. Therefore, to find a leak, examine the brake system starting at the master cylinder in the engine compartment following the hydraulic lines from the master cylinder all the way to the ends of the lines at the wheel brake slave cylinders.
When you find a "wet" area of the brake system, there is probably a leak there. This will be at a fitting, or a crack in a brake line [either the solid metal, or the rubber covered flexible line sections. Also, the pistons in the wheel slave cylinders can deteriorate, and allow leaking at the cylinders which are usually located on inner side of the brake assemblies, or occasionally actually inside of the brake drum [requires removal of the wheel and brake drum to observe].
When you have found the leak, then you must analyze the part(s) involved, and replace the broken or worn one. Good luck.

How do you replace brake pads on Proton Gen 2 I can't fit the the new pads there is not enough space.?
You need to use a Caliper compresser to force the Caliper piston back to home. All it is is a piece of 10mm flat plate with a nut welded to it and a long bolt. When doing this keep a eye on your brake fluid level and empty it a bit if needed, otherwise you will get brake fluid on the paint in the engine bay.
How do you replace a clutch brake on a peterbilt?
To replace the clutch brake on a peterbilt you have to remove the inspection cover on the bottom of the bell housing. You then have to determine whether you have a two piece or a one piece clutch brake. If it is original it is probably a one piece. A one piece will have to be cut off usually with a torch. Be careful because very hot grease can fall in your face. A two piece clutch brake has a hinged side and a push lock on the other. the side with the push lock can usually be released with a screw driver. If the transmission is not removed a two piece clutch brake will have to installed on the input shaft.
What is the clear liquid not water leaking from the bottom of your 2001 Chevy Suburban's Engine?
You engine contains coolant, oil, transmission fluid, P/S fluid, brake fluid, gasoline, & windshield washer fluid. Smell of the fluid, and if it has no smell it is not gasoline. If it is not slick to the touch it is not oil, transmission fluid, or P/S fluid. So that leaves brake fluid, or windshield washer fluid. Brake fluid does have a slight smell, and may be slightly slick, if you pay close attention. Look at the area it is coming from and this is a clue to what is leaking. Try laying a piece of white paper under the vehicle and see what it looks like on paper. Color is a clue.You engine contains coolant, oil, transmission fluid, P/S fluid, brake fluid, gasoline, & windshield washer fluid. Smell of the fluid, and if it has no smell it is not gasoline.

Is it safe to drive a car with a rear cylinder leak?
No. Get it fixed as soon as possible. When you have brake fluid leaking out of your rear cylinder, you are putting lubricant on your rear brake. That is keeping that brake from working. It is also letting brake fluid drain out of the car. Your car needs brake fluid to stop the car. If you lose a lot of brake fluid, you will put your foot on the brake pedal and it will go all the way to the floor and nothing will happen. It can be dangerous when you drive down the highway at a high rate of speed and put your foot on the brake pedal and nothing happens. When you crash your car and turn it into a piece of scrap metal, you could get hurt.
Why would the master brake cylinder make a thrushing noise and no brakes on a 95 Pontiac sunbird and?
There may be air in the brake system. Bleed the brakes and see if this helps. Bleeding the brakes requires two people, a quantity of new brake fluid, and wrench the correct size to open bleed valves on brake plates. The brake plate is the flat plate that the brake mechanisim is mounted on, and has a hose coming to it from the body of the car. The hose carries the pressure from the master cylinder to the individual wheel cylinders, and where it connects to the brake plate there is usually a bleed valve, which is a hexagonal piece of metal with a hole in it. When the bleed valve is loosened, it allows brake fluid to drain from the system. If no one is in the car with their foot pushing the brake pedal to the floor, air will enter the brake system through the bleed valve. So, have someone in the car who can push the brake pedal down, open the hood, and remove the cover from the brake fluid reservoir on top of the master cylinder. Have the brake pedal pushed down slowly (to keep the brake fluid from splashing all over the place. Be careful, brake fluid is highly corrosive!) as the bleed valve is opened, and held down until the bleed valve is closed. Repeat this procedeure three times, and then check the fluid level in the reservoir. Add fluid if necessary and go to the next wheel, which should be the left rear, as you want to start with the right rear, seeing as it is the furthest from the master cylinder. Work the right front after the left rear, and the left front last.

Where do you pour new brake fluid in a 1996 Chevrolet Silverado?
It's been awhile but if I remember correctly, the reservoir should be on the right side when standing towards the vehicle. It will have a black cap that will have 2 little prongs on each side, it will just come off. It will have a blck piece underneath that protects for contaminates. Take it out and por the brake fluid in. It will show a full level at the side. Make sure you use "Dot 3" brake fluid.

You add brake fluid to master cylinder reservoir. This is located on the driver's side of the car mounted on the firewall. On late model BMW 5 series, you cannot see this without first removing the large piece of plastic that covers that area of the engine compartment.
