how long will it take to fix and how much to fix

My breaks just stopped working. The emergency break still works. I had the master cylinder changed and it's still not working. My mechanic can't get the breaks to bleed. ???????

If I drive the car more than 5 miles or 15 minutes, the temp goes way up. Fluid levels are good. Any ideas?

I pressed the gas quickly, it got stuck at 100mph. I stopped the car two feet on brake. Pulled gas pedal to try to release it and it broke into a few pieces. Hanging by a cable. Do I need to buy two parts sensor and pedal? My engine revs up high on its own when I start my car HELP PLEASE ??

My car started running really slow a few weeks ago so i took it to the dealer i bought it from and they told me that it was just a oil leak and that they had fixed it. I payed $250.00 dollars just for that. Now the car stoped running while i was driving to work. I turns on just fine but it doesnt move at all. What could hace caused this?? Someone please explain it to me and how muchos $$ are se talking about?

I have had both replaced car in shop now for 2 months and they are now getting some kind of water reading while testing??

Trans., very slow & kind of dragging before going into the 2nd. gear on Drive ? Once it goes in the 2nd. gear seems to smooth out.
