94 honda accord with no break pressure?

Car had no break pressure. No brake fluid leaks. Bled the breaks thinking that would solve the problem it didn't. Replaced master cylinder (not remaned) brand new. Re-beld breaks now the pedal has tons of pressure and acts normal with out the engine running but while the engine is running the pedal goes right to the floor with minimal breaking. I don't know what to do.

What car deal is better for me?

I'm 20 years old and I don't really have any credit besides me paying my credit card bills. I belong to a credit union and since I don't have credit they let me qualify for a high school graduates program where I'm able to get a car for 12,000 and under. I found a car. It's 10,000. It's a 2008 honda accord with 100,000 miles. The credit union said I can get it with 600 down and 280 for 48 months. They also said they fix the car if some goes wrong with it. My second option is save 1000 for a down payment and go get me a newer car with a warranty. The payments may be higher but it depend on the car. Which deal is better?

Had a mechanic come out and doc my hoses and do my valve cover gasket, I know zero about cars he fixed my oil leak but not my coolant leak and I think it's worse than before he fixed it, it's coming from the middle of the car the upper and lower radiator hoses have both been replaced andy radiator I was told was good and I don't think its the water pump, but like I said i don't know anything about cars. It's a 91 Honda accord ex Automatic
