Brake problem

Hey guys, I have a problem with my ex that has me concerned. Yesterday I was hauling a car trailer with a small-medium size car on it. Hauled it about 30-40 minutes away on roads that average speed was 50. Well, I started slowing down for a turn, and the pedal went to the floor, pumped again, still nothing, third pump I started feeling some resistance, but still no where near what it should be.

My game plan now is new rotors and pads all the way around, and fresh brake fluid. Going to suck all the old fluid out with a power bleeder on all 4 corners. Anything else I should do, or look at? I'm about to leave for a road trip, so I want all my concerns addressed before I leave.

The part that has me concerned, is that I looked at the pads, and I have bare minimum 40% of the pad left all the way around, and my brake fluid is about half full.

My thoughts is that it's old OEM fluid, and is overdue for a change. With lower viscosity due to age, I may have boiled the fluid in a caliper or two. Would you guys agree? If so, am I taking the right action? Anything else you'd look into? Is it a sign that the master is going bad? Or something else?

Need a little more info.

Is the brake warning light on? Do you have a "hard" pedal, that is the vehicle will stop but fees like no power brakes? Do you hear a ticking noise from the left front of the engine?

All of the above are symptons of the vaccuum pump going bad.

I had to replaced my vaccuum pump about every 150,000 miles and every time it had one of the above symptoms.

Well, now that you mention that, I also have a problem with my heater controls not changing the outlets from the windshield to the other setting, this also may have something to do with the vacuum pump.

No brake warning light. No hard pedal, she just went soft to the floor. Ever since, brakes have been fine. No ticking noise. If your asking if I can hear the vac pump when I start it, yes I can.

Well for one this truck uses a hydro booster. So replacing a vacuum pump would do nothing for his brakes.

How is your powersteering, does it work good. Is it low in fluid. Do you see any leaks of brake fluid or powersteering fluid. With the pedal going to the floor and needing to be pumped up. That tells me you are loosing pressure in your brake system. So I would be looking for leaking brake fluid.

Being your pads are worn equally I don't think it is at your brake caliper.

I would look at your master cylinder as well.

Yeah. Happened in another car I drove when I was a teen at the MOST inopportune time. Needless to say that was the last day that car was on the road.

Had flashbacks of that night when it happened in the ex, and I'm doing everything I can on Tuesday to correct it. No way in hell is that going to happen again.

Powersteering semms ok. Sometimes have a buzzing sound when turning the wheel though. She's not leaving any marks at all when she's parked. I'll check the power steering fluid first thing in the morning.
