Default 93 Accord won't stop! MAYDAY! MAYDAY!?

First off, thanks for taking the time to look at this post. OK, here's the problem: Just replaced lower, rear heater hose on the car (after it overheated, for less than 2 min-shut it off rite away). Temp and everything is fine now, but upon driving it for the first time today, noticed it was braking VERY sluggishly (from 55-25-0, i even noticed a slite increase in rpms). Had to put it into park and apply the parking brake coming up my driveway (upon which it revved up to about 5500 RPM's). So the shifter got stuck in park, but got it to unlock with the release key. Brake light switch i know is bad (only the driver side brake light comes on, been that while for awhile, just haven't fixed it yet). NEVER have had this prob B4. All the rite lights come on on the dashboard and everything (including fluid levels), seems to look good under the hood (btw, the horn honks). What could be causing the sudden brake failure? Thx for any help!

Well to start,

You most likely ruptured the Booster in the master cylinder.

Now by trying to stop the car by putting it into park, you've messed up the trans as well.

Good job all around!

If I am understanding right the engine revved very high (approx 5500 rpm) when you put the transmission in park, presumably without your foot on the gas.

If that is the case, look at the pulley wheel on the throttle body to ensure the cables are still on that correctly and not askew or trying to come off the edge. There are only a few potential sources of enough air to make the engine rev that high, including the throttle not closing or the intake manifold gasket shattering. The IMG is a fragile paper thing and can cause some serious intake leaks but I'm thinking the throttle pulley is above the heater hoses and could have been deranged.

If the engine is not running wild (or even if it is), check the large hose from the brake booster to the intake manifold. If that has come off it would certainly cause high revving in park and loss of brake effectiveness.

One more thing that has to be covered. You had the coolant out and refilled, so be sure to bleed the bubble out of it. There is a bleed nipple on the top of the thermostat housing behind the engine. With the engine cold, open that 1/2 turn with a 12 mm socket and close it when a steady stream of coolant comes out. The idle will hunt between 500 and 1700 rpm if you don't bleed the coolant.
