Changing Brake Fluid
 
Hey all this is my first post and I am a noob so donít be to mean :lol:. I had my 05 Grand Cherokee limited with the hemi in the dealership today and they said I needed to change the brake fluid but instead of paying $140 I figured Id try it myself first. Iíve never done this before and Iíve tried to do some research so I just want to make sure these are the right steps.

First thing is to drain the master cylinder of the old fluid and fill it with new fluid. Then remove all the tires and starting with the tire farthest away from the master cylinder, attach a plastic tube to the bleeder and this part im confusedŗ do I have my helper pump the brakes and hold the brake down and then open the bleeder or do I open the bleeder and then they pump the brakes? After all the fluid is clear and the air is out I close the bleeder and move on to the next one.

Is this all correct? Like I said I am new and never have done this before so any helpful advice would be great. I tried finding a how to on the forum but I didnít have any luck so if anyone could point me to one that would be great.

Thanks for the help :D

you are right on..... use a turkey baster type tool to remove as much fluid as possible from the resevoir and full it to the top with fresh fluid. then starting with the rear passenger side, have someone pump the brakes until the fluid comes out clear and bubble free. then continue on the other calipers.

Planning on doing this myself, how much brake fluid should I buy?

The tech at the dealership said they usually use 2 bottles when they do it so thats how many I bought

Right on, let us know how it turns out! I read somewhere that the person pumping the brake should leave the pedal depressed until the fluid stops coming out to avoid air getting in the system...if this is wrong, someone speak up!

Hope Im not too late. One BIG thing to remember is that BEFORE you open any of the bleeders, make sure you have enough new fluid in MC (about half way). ALSO Id suggest you push the brake to the floor as far as it goes and put a piece of wood or something there that fits snug so it WILL NOT go any farther or just know the limits of the epdal and do not push beyond that. If you go to the floor, youve gone too far, you want to keep normal pressure like when driving as you open the bleeder valve.

If you DO NOT do this step, you risk ruining your master cylinder because when you open the lines and push the fluid out, the pedal can go beyond its normal travel and will push the piston in the MC farther than it normally goes and will potentially ruin the seals rendering your MC useless as well as your brakes pretty much. They are not expensive to replace but its a PITA job you do need to because you didnt know or were careless.

Other than this you are spot on with the procedure. Also a helper is to use diff color fluid, if you use something like ATE super blue it will be easy to tell when you got all old out fluid out as the blue will start to come through ;)
