can anyone tell me the correct sequence to bleed the brakes? it says bleed from the farthest from the brakes. is it really the furthest first from the ABS unit or the brake master cylinder? I have read right rear, left rear, left front, right front. this doesnt makes sense to me, should it be right rear, left rear, right front, left front for the brake master cylinder?

Also, how do you bleed the ABS unit?

thanks

 

The instructions you listed never made any logical sense to me.
I have been using closest to farthest for 40 years without any problems.

With ABS it makes even less sense to do it that way since there are now 3 or 4 different lines in the system.

Look at the fluid flow paths and from that you should be able to determine what gets bleed.

 

If you download the factory service manual, the majority of questions like what is this or how do you take off this will be answered as well as how do i bleed my brakes.

 

i have both the hard copy and dl version of th fsm and it just says bleed from the farthest the the closest but im not 100%sure which one is the farthest.

 

from the manual:
AIR BLEEDING
The brakes should be bled whenever a brake line is disconnected.
If a hydraulic line is disconnected at the master cylinder,
start at the slave cylinder farthest from the brake
master cylinder, and move to the next closest slave cylinder
until all four cylinders have been bled. If the disconnection
point is anywhere except the master cylinder, start at the
point closest to the disconnection, and move to the next farthest
slave cylinder until all four cylinders have been bled.

with that said there is a diagram next to the text which shows the order as:
passenger rear
driver rear
driver front
passenger front

 

It's always:

furthest run
second furthest run
third furthest run
fourth furthest run.

passenger rear
drivers rear
passenger front
drivers front.

 

If you have air in the master cyclinder or ABS unit, you start close and work back. That includes loosening actual line connectors at the ABS to remove air first, then move along each line.

In the FD as in latter cars, the master cyclinder has two lines lines; 1 for the front brakes and 1 for the rear brakes.

Both go to the ABS unit. Our ABS has 3 output lines; left front, right front, and rear. All 3 are independant.

So forget that old crap and just do it.

 

how do you loosen the actual line connectors at the ABS to remove air first without having all the fluid drip out of the abs unit all over the place? I cant see putting a pan under it. Also, which lines do I loosen, the input lines or output lines on the abs unit?

 

You shouldn't need to do anything with the ABS. I've completely removed the ABS unit and didn't need to do anything special to bleed the brakes. As far as the master cylinder, if that ran dry, you should bench bleed it. You can do that without removing it by routing some lines back into the reservoir:

Other than that, it's just the normal bleeding procedure. You don't need to turn the car on or off or any of that other nonsense on the forum.

 

One member/friend in CA had some shop totally mess up his system so that normal bleeding did not work as the ABS had trapped air in it. He had to do line by line bleeding through the ABS to bleed out all air. I admit that is an extreme but it can happen.

 

thank you so much for the link/picture of bleeding the master cylinder. see, this is why this forum kicks so much ***, members go out of their way to moron proof how to do things for people like me!
