Re: brake fluid flush (AzSi22)
I thought it was RR LR RF LF, being that it's farthest away from the master cylender going to the closest to the mc.

Re: brake fluid flush (garados)
There are 2 separate parts of the braking system. RR and LF, LR and RF. So you work one system at a time. Thats why you do it in this order.

correct... RR LF are on the same hard line out of the MC.. same goes for LR RF

Re: brake fluid flush (andrew ef)
Im not completely sure if this is true so someone please correct me if im wrong.
From what i can tell, cars with abs are bled diagonally, ending with the front side closest to the abs reservior. When there is no abs the lines farthest away are bled first, and ending with the front side closest to the master cylinder.

Re: brake fluid flush (tilt)
The whole idea of bleeding them in a particular order is to avoid pushing air bubbles into a line that you've already done.
Without ABS, it goes like this.
You bleed all wheels that share the same circuit, starting with the farthest away. Most cars have diagonal circuits, so you start RR then LF, then do the other circuit (LR & RF). Sometimes you start with LR > RF > RR > LF, so it's best to find it in the shop manual for your car. Depends which circuit is primary & secondary in the MC.
Some cars are strange; I had a '74 BMW that had 4-piston calipers in front, and each circuit worked one rear & both front. So each front caliper had 2 hoses & 3 bleed screws.
With ABS, the basic idea is still based on which lines are likely to push air bubbles into which other lines. But the plumbing arrangement is different in different kinds of cars. So the best is to find it in the shop manual for the particular car.
My '95 GS-R goes RR > LF > LR > RF > then ABS which is probably good for any 3rd-gen Integra.
My '98 Accord goes LF > RF > RR > LR and the ABS doesn't have it's own separate bleed valve.
My '01 Saab goes LF > RR > RF > LR and ABS doesn't have a separate bleeder.
If you do it in the wrong order, the only problem is that you might have to go around repeating the entire sequence a couple times before all the air is out.
