I've heard two conflicting reports of what order you bleed the brakes in. One, the "traditional way," supposedly is to bleed in order of the farthest brake from the master cylinder, so right rear, left rear, right front, left front.

I've also heard, though, left rear, right front, right rear, left front.

Does anyone know for sure which is better?

Oh, and another quick question, how exactly do you bleed the master cylinder?

Thanks!

 

in order starting furthest from master cylinder RR, LR, RF, LF

 

If i remember correctly it only matters when u are bleeding the master cylinder. If you are bleeding the master cylinder and the brakes, u bleed the master cylinder first then in order of the farthest brake to the closest brake to the master cylinder.

If you aren't bleeding the master cylinder you can bleed from front to back or back to front it really doesn't matter to tell the truth.

Bleeding the master cylinder is somewhat the same as the brakes. Just have someone push the brake pedal to the floor then open up the lines a little bit by each. Then close all. Continue until u get a even flow from all. If one is bleeding more than others close off that line and do the rest.

Good Luck!

 

WHAT?

maybe i'm not reading it right...but what you wrote doesn't make sense to me. bleeding the master cylinder? help me out here...are you referring to bench bleeding?

 

Hm, I'm not sure what it's called. Another quick question though, do I need to bleed the master cylinder if I'm rebuilding a rear caliper? Or do I just need to bleed the brakes?

 

According to the FSM:

LR, RF, RR, LF

 

I probably didn't say it as clearly as i should have. Now to how to bleed the master cylinder. There really isn't much difference between the bleeding the brakes and bleeding the master cylinder. You just fell it with brake fluid then have someone push the pedal to the floor while cracking the lines. Tighten the lines then tell the person to let it up then push the pedal back to the floor. Then crack the lines again. Continue the process until good pressure is seen from the lines (the person pressing the brake pedal for u should feel the difference by the time u are finish).

I was saying that the only time u really have to worry about order of bleeding the brakes is when u are bleeding the entire system (master cyclinder included). When u are bleeding the entire system, you have to bleed the master cylinder first (like i just explain in the previous paragraph). Then you go from the farthest brake to the closest.

If u aren't bleeding the entire system and just the brakes themselves, you can do the rear first of the front first really doesn't matter you just want to get the air out.

 

Once fluid is still in the master cylinder u only have to bleed that caliper...however if it feel rite u might need to bleed all the brakes.

 

the first paragraph above describes a 2 person standard brake bleeding procedure. what is master cylinder bleeding? without any vacuum or pressure tools how else do you bleed the brakes? how do you bleed the brakes w/o bleeding the master cylinder as you described it? you open the bleeder screw have someone step on the pedal and it forces the fluid out. Before the pedal hits bottom you close the screw. technically you should bleed all the brakes...but if the fluid is fresh and clean then just bleed where you just worked on but still if you're w/o pressure/vaccum tools someone still needs to go in the car and pump the pedal as described above.

 

people...stop talking about "bleeding the master cylinder" unless you're talking about bench bleeding a reman/new unit. there's no bleeder screw on the master cylinder.

as long as you're master cylinder is not drained dry when you unhook the hose...you can reconnect the hose to the new caliper and bleed that wheel only.
