how do i do this on the 4 disc brake system.

These cars utilize a front/rear split system... so just be sure to bleed both rear brakes before you do the fronts.

well how do i go about it?

Start with the rear passenger side and work your way closer to the Master cylinder. DO in this order and you will be cool.

If you knew anything about brakes you would know that does not hold true for all cars.

Do that on anything that is diagonally split and let me know when all the air is out of the system.

Bleed both rears first, the the fronts.

As far as the bleeding procedure get a Haynes manual or search, because it is a really basic process. You pretty much put a hose on the bleeding nut and submerge it in a clear bottle of new brake fluid, loosen the nut, then have a friend pump the brakes until bubbles stop coming out, then once they stop you tighten the nut and move onto the next wheel.

Edit: forgot to add do NOT let the master cylinder's fluid level ever get lower than half because if it gets too low you are just adding air again.

i would only assume that the previous poster that you are correcting would be talking specifically about an f-body since the original poster asked about how to bleed the brakes on his car.

Crap I didn't mean to come off like that... yes it holds true for front/split systems and on our cars, but I think it's worth mentioning the TRUE reason as to why you should bleed the rears first then the front.

Thank You! He asked how to bleed HIS brakes, so I told him.

Interesting.... no one mentioned the two bleeders on the ABS unit.

Moving from "LT1/LT4 Engine Tech" to "Suspension, Chassis and Brakes".....

most cars require a RR,LR,RF,LF sequence. there are some cars that require you to do both backs first and then fronts. you shouldn't have to touch the abs circuits unless pressure bleeding. when pressure bleeding, the abs will try and compensate for the pressure and it will resist you. this will often require a scan tool to tap into the abs system and tell it to back off (newer dodges are famous for this).

i found it easy to use the mightyvac when bleeding my lines. just crawled under the car and did the rr, lr, rf, lf (start with the bleeder [on our cars] that is farthest from the abs system) in that order to get all the air out. i dont know how many people recommend using it, but it worked well for me. it comes with all the proper attachments for connecting to the bleeders without letting air back through the line. it was a one man operation. no pumping the brakes. just make sure that the fluid stays full or you'll hate yourself later.
