90 Beretta GT - Multiple issues - brake,signal,clutch,power steering

I've owned my Beretta for over a year now, and have always had little troubles here and there. And now with summer around, i'd like to try and fix everything. if possible.
Here is a list of things that don't work, or have troubles

Brake Lights
Signal Lights
Revs up while idling
Leaking Power Steering
Leaking Brake Fluid
Clutch is shot (Most likely from the leaking fluid)

the list could go on and on.

-but my main concern is really the brake lights and the signal lights, I removed the brake switch, since I found out that if i tap my turn signal in a bit without the switch in, that's an alternative way to get my brake lights to work. Also works for my signal lights, but i have to pull it ion all the way, turning on my bright and down or up, to get my signal light to work... I'm assuming it's my turn signal switch, but i don't know for sure... wondering about that....

-The rev'ing up while idling, i'm assuming is a head gasket leak...

-Power steering leak, i'm not sure, since i haven't found where it's leaking from..

-The brake fluid leak i've noticed a few times on my passenger side, but i was never sure where it was leaking from, since my master cylinder was on the driver side, so i was clueless, then i've been readin up and i'm thinking it could be my slave cylinder, since just yesterday on my drive home from work, i started to find it almost impossible to switch gears, since no matter how hard i pressed down on the clutch, it didn't do anything at all.... so i'm told to bleed to air from the slave cylinder.... but my problem is i don't know where exactly to find it.

-oh ya and another thing, someone told me i need to replace the hub on my front right wheel. i'm not sure why, and i have no idea how to...

I know i have a long rant here. but the thing is, this is a good car, it's been good to me, well, sorta, but i wanna fix as much as i can as soon as i can,
so if anyone is able to help me with anything on the list i will be very greatful.

Thank You

I would say that your turn signal switch is shot for sure cuz I got the exact same problem with mine (needing to pull on it to get the signals to flash). My dad and I have had it apart a few times and it was remedied for awhile but the symptom always comes back due to the contacts getting wore out. Best bet is to replace it with a new one.

The problem with your clutch is probably the slave cylinder has let go. This happened to me about a month or 2 ago and it results in the clutch disc not being able to be released from the flywheel. I replaced mine but it took a bit to find the right part for my car (89 Beretta GT but needed an 87 or 88 slave cylinder). It wasn't real hard to replace but yes you do need to bleed it and it is best to have another person help you with that part. You can look on autozone.com for the repair procedures.

Do you hear a hum at highway speeds? That is the only reason I can think of that someone would tell you to replace a front (or rear for that matter) hub. The wheel bearing is part of the hub and the hum means that it is shot or getting to be shot and it is best to replace it. I believe that there are 3 (maybe 4) bolts that hold the hub on and the axle nut. once you got those off then take a lead hammer or something of soft material and tap on the axle to free it. It should just slide out of the splines and the hub should come off.
