Ford Ranger Problems

I have a 1993 4X4 Ford Ranger 4.0L Automatic Transmission with approximately 187K miles on it. The other day while driving, it lost power and I noticed transmission fluid leaking from what appeared to be the front pump seal area. At the same time I noticed my brakes also seemed to have a different feel at the pedal. The pedal seemed to be stiffer than normal. I have been noticing the strange brake pedal feel for a couple months, usually when the engine is hot.

As for the transmssion leak, I read that a faulty cooling system can cause a transmission leak at the front pump seal area because the radiator is not properly cooling the transmission fluid. Too much heat build up causes expansion thus the leaking. With that in mind I checked my coolant system and I noticed I have a leaky radiator.

The strange thing is that after I noticed the transmission leak the other day, I parked the vehicle and let it sit for a few days. When I went back out to check the coolant system issue that I read about, I discoverd that I had no brakes. The brake pedal goes completely to the floor with very little resistance. Is it possible that I simply have two unrelated problems or do you think the problems are common? By the way, I did start the engine and I noticed the transmission was not leaking. I assume the engine had cooled off and sealed up the leak.
