  1. So im having a little issue with my brakes. I have a 99 Wj (grand cherokee) and my brakes go straight down to the floor and it stops like 2 seconds after it hits the floor. My brake fluid resivior emptys in like 4 days and i keep putting my fluid in. And sometimes it stops perfect after the fluids put in and sometimes it just stays the same. Wether its working good after the fluid or staying the same the resivior emptys around the same anount of time. Any ideas i have looked everywhere and cant get a deffinitive answer..
     
  2. There is a leak in the brake line somewhere, if you park for a day and then look at the ground you should see where about the leak is relative to where the car and the droplets are. I say that because it could be in any of the lines to the 4 wheels. The pedal hits the floor because you have a leak and cannot maintain fluid pressure.
     
  3. Ditto to what roorforcrumble said. Plus if you have let the reservoir get empty/if the leak is big enough you no doubt have air in the line to boot! Dropping that much fluid you must have a spot on the ground or at least dripping on to the back side of a rim or tire if you have a bad wheel cylinder(drum brakes) or caliper(disk brakes). If it was a case of the brake peddle just going to the floor then we could assume a bad master cylinder but the lost fluid is a clear indicator of a leak someplace.


    Order of action to correct is.....


    1) Find leak/where fluid is going
    2) Fix leak
    3) Bleed ALL 4 brake lines
    4) Enjoy your rig again
    We will assume your Jeep is NOT a stick shift. If so you could have a leaking clutch slave cylinder(the brakes and clutch slave all run off the brake master cylinder) but then you would be having shifting issues as well
     
  4. Nope automatic lol how much do brakelines typically cost?
     
  5. My baby the refrigerator lol

  6. Depends on what is leaking and gone bad. If you are just looking at the flexible rubber section from the main hard line to the caliper maybe $30-$50. If it's a main hard line them a good bit more. Find that leak first. Check over the master cylinder and booster real good first.
     
  7. Also Check where the master cylinder bolts up to the vacuum advance on firewall
    If there is fluid leaking behind the back of the master cylinder where the bolts are , It could be a bad master cylinder and need new or rebuilt one.
    By the sounds of it , it is a slow leak down , could be a rust pin hole in the line hard to find.
     
  8. Im taking it to a shop today to get a diagnoses and to get an estimate to fix it. Wish me luck
     
  9. Good Idea
    Brakes are to important to mess with if you have never worked on them before
    Smart Dude
     
  10. Yup brake lines somewhere or master leaking at firewall..id go ahead and replace the master along with it anyway
     
  11. If you keep driving it like this it will eventually let go and you will loose your brakes all of a sudden as you push down hard on them the leak will explode all the fluid and thus no way to stop.
     
  12. Do any young people still work on their own cars
    When I was growing up it was I'm going to the parts store I have to fix my car.
    Now a days everyone is like I need to go to the dealers...............................


    What happened?
     
  13. Shit I'm 22 been working on cars since I was old enough..along with all my friends the car scene is alive and well with young people.
     
  14. Cars aren't as shitty as they used to be...but seem to be considerably harder to diagnose some issues, like ECM codes....
     
  15. You are one of the few, the young people now a days seem to be very lazy and depend on Mommy and Daddy for a lot .
    I have a scan tool and work on all my new cars so it's not that hard and I'm only a backyard mechanic.
    But nuff said
    Dude needs his brakes checked out
     
  16. i had a mitsubishi eclipse before this jeep and i did a lot of my own work. I just dont wanna mess aroundv with the brakes lol
     
  17. Glad to hear
    It can save thousands by being able to fix your own cars
    Dealers will beat you up bad.
    When I grew up it was nothing to rip a engine down and rebuild it and re-install and have the car run.
    Now a days the engine compartments are so tight , it's almost impossible to do so without 50,000 dollars worth of tools
    So I understand.
    Nice to see there are guys out there still getting their hands dirty.
    I Loved working on my cars when I was younger.
    Hope you do to.
     
  18. Well I might not be young anymore(40yrs old) but I can turn a wrench well enough to swap a super nasty 350 Chevy into a 78' Datsun 280z and a tough 406 smallblock Chevy and T56 tranny into a Lexus SC300.
     
  19. My money is on the brake booster/master cylinder. I'm not sure if they are the same thing.


    Having a dealer fix your brake problem is going to be at least $500.
     
  20. Part wussification of society and part increased levels of technology...I can do my own brakes on the cars that didn't have ABS, but the ones that have it are so easy to screw up functions of some other system.


    Granted, as I got older, I have also found it easier to simply go to the shop on some things since I have the funds to do so, but damn I miss the days of a tune up being as simple as checking/adjusting points and putting in the eight or twelve plugs (V12's are a pretty thing). Or brakes being a matter of pull the wheel off, undo a bolt or two and have easy access to the disc pads. Drum brakes were no fun because those springs were a real bitch...


    But yes, it amazes me to see so many guys going to a shop on things dad made sure his little girl knew how to do so many years ago...
