    i can lock up my tires now, just my bf doesnt think my brakes will work very good when i do the v8 swap. but if there truly is no difference in the stopping power between the two set ups then i wont bother. ill just work on fixing my system up better. and figure out why my brake pads are still brand new when i do plenty of braking. ill probably have to replace all the lines and re-bleed the lines.

    You'd be amazed how flex lines swell over time. We cut the ones on a friends Challenger over the weekend, and the inside diameter was less than an 1/16 of an inch, there's no way you could push enough fluid through them to fill the piston on the caliper to stop any car.

    I think your disc brakes are probably just fine. If you are comparing them to today's cars....there is no comparison. Today's cars have multi-pistons, bigger rotors, 4-wheel disc brakes, ABS, etc.

    Dave made a good point. Also make sure your back brakes are adjusted properly. If they aren't right your pedal will go down too far and the fronts will handle more than their fair share. When it comes to brakes, it has been my experience that the only way to know they are done right is to do them yourself.. If you don't have much experience, just use a repair manual and get learning!

    Post a picture of your leg and we can tell you if it is too skinny.

    lol my leg isnt skinny, trust me, im a big girl, i work out and do mixed martial arts.

    i can do brake jobs, i just havent touched my back ones in a while, so yes you may be right, Fish out of water. do to my negligence of the back brakes its causing the fronts to handle everything and my pedal a lil spongey.

    i dont own a new car, nor do i drive them. so i cant compare it to anything. this car is my first car, i learned to drive in it, and i learn about cars thru it. its my baby.

    Oh, you are a girl?:hmmm: Post a picture of yourself we can tell if you are a big girl.

    But seriously if you are going to have a look at the back brakes...
    Always treat the dust like its asbestos. I hose it clean before I start. Keep it wet. Get yourself a few brake tools to make it easier. Spring nut tool, adjuster spoon, spring pliers. Use a manual and still, only do one side at a time so you can use the other side for reference. could use a digital camera too. And best if you can get someone with experience to help you and explain stuff. I cant say I don't know any women that do their own brakes! Good luck getting it straightened out.

    the rubber flex lines from steel line to cylinder are a massive difference when they start to wear, he is right on that. also make sure their well bled because even a little bubble can make them mushy. at least you dont have to worry about the power assist assembly starting to go bad

    I'm gonna come at this from a different direction. I disagree. Power assist brakes do make it easier to stop because the vacuum booster assists you in pressing down the pedal so you get the maximum pressure in the system with less effort. No, power brakes won't make up for a system that's unsound mechanically, just like power steering won't fix a car that has worn steering components.

    Another thing to think about is the master cylinder that's on the car. Power/non-power master cylinders generally have a different piston size, and if you put a power M/C in a car that doesn't have power brakes you would get increased pedal effort.

    I actually added power brakes to my '72 and then upgraded to a hydroboost system that uses power steering fluid instead of vacuum when I converted to rear discs because the vacuum booster didn't provide enough boost for a comfortable brake pedal feel.

    And no, I'm 6 feet tall, around 225 pounds so my leg isn't particularly skinny. :)

    Just my take on it, I like my power brakes and I think the conversion is worth it.

    lol ok, well im gonna have to see whats up with my system before i do anything anyways.
    i havent touched my rear brakes in a few yrs, so maybe its time i pay attentio to them. I was gonna see about changing the back to discs too but didnt know where to go pr which car i could pull a rear end from that that will fit my car properly.

    i wish there was a simple maverick part interchange encyclopedia, just look up a part and see what other cars you can cannible that part from. that would be awesome!!
