I have a 280 Diesel Turbo Double Cab with a alternator problem. Problem is brake fluid leaking from the rear bottom side of the alternator, only during braking. I'm not sure how this is possible? How do I fix?

Re: Alternater Leaking Brake Fluid
I'm not sure if it is brake fluid or engine oil but i used to rebuilt alternators and the izusus have the engine oil pump integrated with the alternator, so all what you have to do is get another alternator from auto parts or find a place and have them rebuilt your alternator, im sure you will find a good place in the yelllow pages. they have a o-ring inside that when it gets damage it will start leaking engine oil, or brake fluid like you say, but definitive there is a pump behind the altenator and the seal must to be replaced

-Double check. No leaking....? -If not leaking. When you bleed it. you might need some one to help you pump the brake. -Make sure Pump the brake (Hole down still)/Now open or release the fluid and Closed BEFORE release the brake pedal. Repeat this until no bubble. And make sure the fluid reservoir never empty to Bottom. You should be good to go.
If you have no evidence of leaking outside the drum, most likely your brake piston is leaking or the drive shaft seal is leaking. Pull off the drum and look for the piston which spreads the two brake pads normally situated at the top. Inspect for leaks. If the fluid is thin, it is most likely brake fluid. If it is heavier like oil and really stinks, it is gear oil from a leaking seal.
well if you are losing fluid you definatly have a leak as brake fluid is not a "topping off fluid". you could have a leaking master cylinder either externaly which can be seen on brake booster or it can be leaking into the brake booster filling it with fluid. other than that you also may be leaking from your brake hoses(one hose at each wheel), calipers(front wheels and rear if all wheel disc brakes), wheel cylinders (if you have rear drum brakes), or metal brake lines due to rust and corrosoin (run from master cylinder to each brake hose). please rate 4 thumbs if helpful.
The leaking could be from your brake line, can you tell what color the fluid is and the texture? is is slippery or feels more like water? If it is brake fluid leaking that means you have a broke or busted line or a caliper/brake cylinder leaking which needs to be fixed quickly.
From your discription, if it is square in shape and has 3 brake lines attached to it, it is the rear brake junction block. Double check and make sure it isn't a brake line that is attached to it. If the leak is above the rear axle on back of the wheel, that's the rear wheel brake cylinder.
It appears the rear axle shaft seal is leaking. You will need to pull the axle and replace the seal. Then check the rear end for adequate gear oil. The iron filings I am not to sure about. It sounds as if something came loose from the brakes or brake hardware and got chewed up in the drum. You will need to replace the brake shoes and maybe the brake hardware kit. Always change the shoes or pads on both sides when working on brakes, rear or front. If the inside of the drum is not perfectly smooth it will need to be turned or replaced. If this were brake fluid leaking from the wheel cylinder the master cylinder would be low on fluid and your brake pedal would go down much further than normal.
if your car has rear drum then the wheel cylinders could be leaking and in need of replacement. If it has rear disc brakes then it could be leaking fluid where the brake hose goes into the caliper or the brake hose my be worn or have a hole in it. Or it could be a a brake line. You should have it checked because you don't want air getting into the braking system.
