done a search but don't have clear ideas...
is it just like bleeding process, but longer until you see new fluid comes out from the bleeder?
anyone???

 

You can either bleed them normally, one wheel at a time, until new fluid comes out like you said or you can do it the lazy way. Open all four bleeders and take your new bottle of brake fluid and you can either flip it upside down and put it in the reservoir, like a water cooler, or just keep topping it off. Let it run out until you get new fluid from the bleeders, can take some time.

 

If your doing it with all bleeders open at the same time, be sure not to touch the brake pedal with them open and DONT let the reservoir run dry or you will get a lot of air in the system.

 

I usually do one at a time, and go until I get clean fluid. I bleed each wheel once until I get clean fluid and go around again just to make sure nothing backwashed. I bought 2 liters and it was more than enough 1.5L would probably do fine.

 

A vacuum pump will work wonders for this. Just pull it through each corner making sure the reservoir stays full. Much quicker than having two people one pumping and one manning the caliper.

Also, some shops will do this for you for less than $40. They presurize the master with a bleeder system and bleed each wheel til clean fluid comes out. Takes them about 20 minutes start to finish and you dont have to worry about pumping at the wrong time or making a mess all over your garage.

 

Mighty Vac bleeding kit works, can be done by yourself that way.

Do not over bleed and drain the master cylinder.

Suck out the old fluid at the master, refill with new and start bleeding until you get clean fluid, starting at the right rear. Repeat at each wheel. Check master often so you don't drain all of the new fluid from it and introduce air from the top.

Never use old fluid, sealed fresh container is the best. Stuff absorbs water when opened.

By the way it is "BRAKE FLUID" not "break fluid" different word.

Mighty vac sucks I'll sell you one! Forget what everyone is telling you by far the best and easyest way is to use speed bleeders, do a search. I have them on my stock brembos, my EVO clutch line, wifes scion tc brakes and my cbr 1000rr brakes/clutch. You can bleed the whole system in under an hour with no hassle at all! and that includes jacking up each side and tire removal. You can get napa bleeders if they are local. I think its www.speedbleeder.com

 

I like using the Motive power bleeder. It keeps the master cylinder full for you and makes the job very very easy

One of the issues with speedbleeders is the potential for leaking air into the system after the thread coating wears off.

 

I've never seen that before, but it looks perfect!

I just do it the old-fashioned way. And it works, but for $60 I might give that Motive gimmick a try.

 

grab a friend or neighbor.... and ask them to help you step on the pedal.

 

That would work perfect, pretty much the same thing that a shop uses except a little smaller.

I would definitely consider buying one of these also. Seems to fit the bill.
