Brakes always seem like a simple job.theyre small. theyre simple. but every time, working on my brakes is hell. Last time i replaced my master cylinder because i wasnt getting good pressure, and i took it for a test drive at 8ish (After the auto store closed) and i pushed on the brakes and they held, then lost all power, and i had no brakes except the front. so it really didnt stop the jeep. i pulled it into my garage, and saw both wheels leaking fluid. i said ooooh crap this isnt gonna be good. i pulled off the wheel, pulled of the drum, and the whole brake assembly came apart and fell to the floor. the wheel cylinder was blown open from the higher pressure of the new master cylinder. I pulled off the other wheel and it was the same deal. So, i take my dads car to school the next day, stop by the auto store and pick up a couple cylinders and some brake fluid. I do some homework or something, and start working on my jeep at like 7. of course, the bolts holding the cyinders in have about 4 inchs of corrosion on them, and it takes me forever to take those out. I start putting it all together and im thinking all right so far so good ill be driving it tommorow.. and then, i go to put on the self adjuster fin thing that holds the brake adjuster in place, and it breaks in half. i look at my watch and its exactly 8:00, the closing time of the store. The story does have a happy ending though. my brakes work.
oh and as for advice, if you dont feel confident working on it, by all means take it somewhere... brakes are worth it.
